Landraces Under Bineng, La Trinidad, Benguet Condition. Benguet State University, La
Trinidad, Benguet.
Adviser: Janet P. Pablo, M. Sc
ABSTRACT
Nine different landraces of non-glutinous rice were evaluated to identify the best
landrace/s with the highest yield and resistance to stem borer and neck rot and to
determine the profitability of growing the non-glutinous rice landraces under Bineng, La
Trinidad, Benguet condition.
The different landraces of rice that were evaluated were Balisanga, FK, Bayag,
Maltiha, Sapaw, Ba-ay, Makaneneng, Gulitan and Kayamsing.
The nine progenies were sown in a seedbed under the greenhouse and
transplanted in the field. Differences among the landraces were noted in the seedling
height and number of tillers produced. All of the landraces were observed to be normal
and vigorous at seedling stage.
Rice landraces Sapaw and Ba-ay had the highest number of filled grains, weight
of 1000 grains, total yield, computed yield, and realized a positive ROCE.
All of the rice landraces showed resistance to neckrot and blast but most were
infested by rats except for Ba-ay and Sapaw.

INTRODUCTION
Rice has been considered as the staple food for Filipinos. This is supported by the
continuous growth of rice production in our country. The role of rice in our society has
been considered as being the gift of life (Zaffaralla, 2004).
Rice
(
Oryza sativa L.), belonging to the Graminae family is cultivated in warm
and cool climate, and is a semi – aquatic plant. PhilRice (2001) stated that most of Asia’s
population is highly dependent on rice, it is the main part of their meals especially
Filipinos. Zaffaralla (2004) added that rice serves us so well in life and art and is a truly
life giving grain.
The Central Cordillera Agricultural Program (CECAP and PhilRice, 2000)
defines traditional rices as the varieties that have not undergone improvement in formal
breeding and research institutions. At present, traditional rice varieties are grown in the
higher elevation while the high yielding varieties are grown in the lower elevations. In
the highland areas, rice grows in 6 -7 months, has low tillering, awned grains and tall
stalk.
Traditional rice are mostly tall (160 -200cm ) with droopy leaves, photoperiodic,
low yielding, late maturing and less responsive to nitrogen fertilizer. These varieties have
been bred through time to gain dependable yields under low management levels. These
varieties are good sources of resistance and grain quality traits. These varieties also
endure adverse environments such as submerged regions and in areas with low soil
fertility (PhilRice, 2001).
At present, some municipalities of Benguet produce modern rice varieties which
replaced the traditional varieties. These modern varieties are continuously produced and

currently adapted in our locality. However, traditional rice is still preferred by tribal folks
in the Cordillera Region as reflected by the continuous production of these varieties up to
the present time. These varieties are not only produced for food but it is an important part
of the culture of the Cordilleran.
In order to preserve these varieties, production of traditional rice must be done to
increase the yield and widen adaptation. The results of the study can be used to determine
the adaptability of rice landraces in La Trinidad and to restore the traditional rice varieties
as one of the grandeur of the Cordillera Region. Findings can also serve as reference for
future research.
The study was conducted to:
1. evaluate the nine rice landraces based on their growth and yield in Bineng, La
Trinidad Benguet condition;
2. identify the best traditional rice landraces with the highest yield and resistance
to stem borer and neck rot; and
3. determine the profitability of growing the non-glutinous rice landraces under
Bineng, La Trinidad, Benguet condition.
The study was conducted at Bineng, La Trinidad, Benguet from August 2009 to
March 2010.

REVIEW OF LITERATURE
Varietal Evaluation
Varietal evaluation is the process in plant breeding that has comparison to
promising lines developed by breeders. It involves selection where plant breeder’s choose
the best performing variety among the developed lines in terms of yield, stress
adaptability and resistance to pest and diseases (Sunil, 1990). In addition, Kang (2002)
stated that the importance of conducting varietal evaluation of different crops is to
determine and select a desirable variety that performs well and thus be recommended to
farmers.
According to Hay and Porter (2006) plant breeders have sought to improve further
the yield, reliable and quality of crops by improving adaptability to different climatic
environments and to ensure that the life cycle of particular genotypes fit the constraints of
the local environment.
Reiley and Shry (1991) reported that the variety must be adapted to the area in
which it is grown. Different varieties which were grown under the same method of
culture have a great variation in the yielding ability. A variety that yields well in one
region is not a guarantee that it has the same performance in another region.
The variety to be selected should be high yielding, pest and diseases resistant, and
early maturing so that the production would entail less expense, and ensure more profit.
Selecting the right variety will minimize problems associated with water and fertilizer
management activities (Bautista and Mabesa, 1997).
In addition, Lorenz and Maynard (1988), stated that selection of the variety to
plant is one of the most important decisions the commercial vegetable grower must make

each season. The variety should have the potential to produce crops at least equivalent to
those already grown. The most economical and effective means of pest is through the use
of varieties with genetic resistance to disease.
Furthermore, varietal evaluation is important in order to observe performance
characters such as yield, earliness vigor, maturity and quality because varieties has a wide
range of differences that affects the yield performance of the plant (Work and Carew,
1995).
Evaluation Trials
Roxas (1996) revealed that the evaluation for the yielding ability of the Ifugao
rice varieties, both
Pinidua and
Tinawon types showed high yield potential.
Pinidua of
the Indica group were moderately susceptible to cold blast while the
Tinawon of the
Japonica group are highly tolerant. On rice blast reaction, both ecotypes possed moderate
degrees of susceptibility, the
Tinawon rice varieties, showed, moderate resistance to cold
blast and to lodging and has a shorter growth duration. For grain quality, Ifugao rices has
a brown caryopsis and high milling recovery.
CHARM (2002) reported that the PSB RC96 or
Ibulao, the NSIC RC104 or
Balili
and the PR27137 CR153 were preferred by the farmer cooperators to be adapted and
reproduced in Bakun Benguet.
Cultural Requirement and Management
Martin and Leonard (1970) stated that the best soil for rice is slightly acid to
neutral, but it is best grown on soils that have a pH range of 4.5 – 7.5.

PhilRice (2001) emphasized that rice should be planted at two seedlings per hill at
a distance of 20 cm x 20 cm. Empty hills must be replanted not later than 3-5 days after
transplanting to avoid uneven maturity of the crop. Close space density results in mutual
shading, less tillers, smaller panicles, and lanky and weak seedlings.
IRRI (1993) mentioned that irrigation should be done at a depth of 2-3 cm for wet
and one cm for dapog method. At vegetative stage, water should increase from 1 to 10 cm
while during the reproductive stage, the depth of 5 to 10 cm is maintained. The most
critical water deficit is the period from 10 days before flowering, which caused high
percentage of sterility, thereby reducing grain yield.
PhilRice (2001) stated that it is best to harvest rice when 80% of the grains are
matured. This is indicated by a yellow panicle or straw. Delay of harvesting may lead to
grain shattering. While too early harvesting may produce immature, chalky grains that
break easily during milling.

MATERIALS AND METHODS
Seedbed and Land Preparation
Nine seedbeds were prepared for the nine landraces of non-glutinous rice under
greenhouse condition. One variety was sown in one seedbed to avoid mixture of the
different non-glutinous rice varieties and necessary labels were placed in each seedbed
for easy identification. Before transplanting in the field an experimental area of 150 sq.m
was prepared for the nine landraces which were replicated three times. Each plot
measured 1m x 5 m.
Lay – out and Transplanting
After
land
preparation,
the experiment was laid out following the Randomized
Complete Block Design (RCBD) and was replicated three times. The thirty-day old
seedlings were transplanted at once. One vigorous seedling per hill was transplanted at a
distance of 20 cm x 20 cm between hills and rows as shown in Figure 1 and 2.
Hand weeding was done 20 days after transplanting for the plot to be kept weed
free. Rats were observed during the conduct of the study. Thus, because of this, a net and
screen was placed in the rice field to control the pest and birds. No fertilizers were
applied to the rice plants.

RESULTS AND DISCUSSION
Meteorological Data
The monthly temperature, relative humidity, amount of rainfall, and light
throughout the conduct of the study are shown in Table 1. It was observed that 24.7oC
was the maximum temperature during the month of September, while the minimum
temperature observed in December was 10.9oC. The relative humidity increased in the
months of August to October then decreased during the month of November to January.
The monthly rainfall ranged from 1.0 to 72.2 mm. Highest rainfall amount was gathered
in October. The highest amount of sunlight was observed during the month of December
which is 425.8 min. and the lowest amount of sunshine duration was obtained from
November.
Vergara (1992) reported that the temperature favorable for cool and warm rice
production ranges from 16-25oC and 25-35oC, respectively. De Datta (1983) added that
low temperature causes low rice yield. Injury due to low temperature is a major constraint
to rice production in hilly areas in the tropics and subtropics. Rice production is affected
by not only soil fertility and water but also the temperature of the place of production
(Yoshida, 1981).
Soil Chemical Properties
Soil pH. The soil pH of the soil before and after transplanting was 6.15 which
favors the growth of rice since the pH range for rice is 4.5-7.5 (Martin and Leonard,
1970).

Soil organic matter (%). Table 2 shows that the percent soil organic matter
before planting was 3.50 %. It was observed that the amount of organic matter in the soil
before planting and after harvesting is the same because of the presence of azolla. Alam
(2004) stated that azolla can be a potential source of green manure for tropical rice
production due to the N that it can contribute to the rice crop. Thus, instead of utilizing
the residual nutrients, the rice plants might have used the Nitrogen released by the azolla
plant.
Nitrogen (%). No change in the amount of nitrogen content of the soil was
observed. Although, nitrogen is crucial for several physiological and biochemical
reactions during vegetative and reproductive phase of the plant (Krisma, 2002), the lack
of change in soil Nitrogen implies that nitrogen from azolla is enough for the growing
rice.

Phosphorus (ppm). Phosphorus content of the soil decreased after harvest from
140 to 73 ppm. The decreased P could be attributed to the none application of fertilizer
and the plant utilized the residual P in the soil.
Potassium (ppm). As shown in Table 3, there was an increase in the potassium
content of the soil at harvest. The initial and final potassium content of the soil was 72
and 92 ppm, respectively. This may be because K was not utilized by most of the plant
during the grain development as it was eaten by the rats.
Plant Vigor
The plant vigor is shown in Table 3. Result showed that the plant vigor at seedling
stage of the nine traditional non-glutinous rice were normal to vigorous, where majority
of the seedlings have 4 to 5 leaves and some have 1 to 2 tillers.
Seedling Height
Significant differences on the seedling height of the nine traditional landraces of
rice before transplanting is shown in Table 3. It was observed that
Sapaw was
significantly taller (33.65 cm) as compared to the other rice landraces. The significant
differences among treatments could be attributed to their varietal characteristics or
adaptability to the environment

Transplanting to Tillering
The number of days from transplanting to tillering is shown in Table 4 where no
significant differences among the landraces is observed.
Kayamsing produced tillers
earlier than the rest of the landraces at 64 days after transplanting followed by
FK and
Gulitan (68). The latest to produce tillers at 79 days was
Maltiha.
The vegetative stage is characterized by active tillering, gradual increase in plant
height and leaf emergence at regular intervals. Active tillering refers to a stage when
tillering rate – the increase in tiller number per unit time- is high (Yoshida, 1981).

Number of Days from
Transplanting to Booting
The number of days from transplanting to booting is shown in Table 4. It was
observed that among the landraces evaluated,
FK booted earlier at 78 days as compared
to the other Landraces that booted two to twelve days later.
Sapaw was the last to boot
with a mean of 90 days. This maybe attributed to their genetic make-up, varietal
characteristics and adaptability in Bineng, La Trinidad, Benguet.

Number of Days from
Heading to Ripening
Number of days from heading to ripening of the nine landraces is shown in Table
4. Observations showed that
Balisanga, FK, Bayag, Gulitan, Kayamsing ripened earlier
at 30 days followed by
Sapaw and
Makaneneng at 31 and 32 days, respectively.
Maltiha
and
Ba-ay was the latest to ripen at 34 days from heading to ripening.
Number of Tillers
Results revealed significant differences on the number of tillers as shown in Table
5.
Ba-ay significantly produced the highest number of tillers with a mean of 33 followed
by
Maltiha (25) while the rest of the landraces produced 10 to 14 tillers.
Vergara (1992) mentioned that plants produced more tillers during the wet season
compared to the number of tillers produced at dry season. Rice plants also grow faster at
warm temperature than in cool temperature. Thus, the high number of tillers of
Ba-ay
may be due to the wet season from August to October and to varietal characteristics.
Number of Productive
Tiller per Hill
The number of productive tillers per hill showed significant differences among
the landraces (Table 5). Most of the landraces have comparable number of productive
tillers with means ranging from 6 to 10. Rice landrace
FK produced the least number of
productive tillers (3).
According to UPLB (1983), not all tillers produce heads, some tillers die while
others remain at the vegetative stage since there is competition among the tillers for

nutrient and light. Thus, the production of tillers alone may not be a good gauge of the
yield potential of rice.

Panicle Exertion
Table 5 also shows the panicle exertion of the nine rice landraces. Results showed
that
FK and
Ba-ay had a well exerted panicle (scale 5). This means that the panicle base
appears well above the colar of the flag leaf blade. On the other hand,
Makaneneng was
the only landrace which was moderately well exerted wherein the panicle base is above
the collar of the flag leaf blade. Other landraces were just exerted (3) which means the
panicle base coincides with the collar of the flag leaf blade.
The well exerted panicle of
FK and
Ba-ay implies that those landraces have
longer panicles.
Height at 165 DAT
The height of rice the plants was measured from the base of the plant to the
panicle tip excluding the awn at harvest. Table 6 shows the height of the nine rice
landraces at maturity. Statistically, there were no significant differences noted among the
rice landraces, though numerically,
Sapaw was the tallest among the other landraces
(119.48 cm). The shortest among the landraces evaluated was
FK with a mean height of
88.39. These differences could be attributed to their varietal variability.
PhilRice (2001) stated that traditional rice are mostly tall with droopy leaves and
are late maturing.

Stem Borer, Blast (neck rot) and Rat
Damage Evaluation
Evaluation of white heads was done accordingly based on the rate of infestation.
For the white heads and blast, all entries were found to be resistant. All the entries were
also resistant to stem borer damage as shown in Table 7.
Most of the landraces evaluated were infested by the rats because of their
aromatic characteristics.
Sapaw and
Ba-ay are the only landraces which were not infested
by rats. It was observed that as the rice matured, rats cut the tillers and eat portions of the
developing head. As the rice heads mature, rats feed on the individual grains.

De Datta (1981) reported that rodents, particularly rats, cause serious damage to
the rice crop in all growth stages. They eat seeds (in-direct seeded rice) and seedlings,
they grow off tillers, damage plants, and seed rice grains at various stages, they also
destroy attached, stored, threshed and hulled rice.
Number of Filled Grains and Unfilled Grains
Statistically, results showed that no significant differences were observed on the
number of filled and unfilled grains. Among the different rice landraces evaluated,
Sapaw
had the highest number of filled grains with a mean of 65 while
Gulitan had the lowest
filled grains (5).

On the number of unfilled grains per panicle,
Makaneneng had the highest
number of unfilled grains per panicle with a mean of 65 followed by
Sapaw (63) while
Kayamsing had the lowest number of unfilled grains per panicle with a mean of 16. This
is due to the damage of rats in most sample plants.
Weight of 1000
Filled Grains
Statistically, results showed no significant varietal differences on the weight of
1000 filled grains produced (Table 9). The weight of 1000 filled grains of the different
landraces ranged from 8.89 to 25.13 g.
Sapaw obtained the heaviest weight with a mean
Evaluation of Nine Non-glutinous Rice Landraces
Under Bineng, La Trinidad, Benguet Condition / Arlene B. Bautista. 2010
24
of 25.14g while the lowest weight was obtained from
Gulitan with a mean of 8.89g. This
is due to the grain characteristics such as the size of grains and the damage caused by
rats.
Yield per 5m2
The yield per 5m2 is shown in Table 9. It was observed that among the nine
landraces evaluated,
Ba-ay produced the highest total yield with a mean of 1,310 g
followed by
Sapaw weighing 1,181 g. The lowest yield was obtained from
Gulitan with a
mean of 251 g. This is attributed to the differences in the number of grains, weight of
1000 filled grains and rat damage.
Computed Yield per Hectare
The computed yield per hectare showed that
Ba-ay had the highest yield per
hectare with a mean of 2,621 kg which was not significantly different but numerically
higher than
Sapaw with a mean of 2,362 kg per hectare.
Gulitan obtained the lowest yield
per hectare with a mean of 431 kg. Such differences follow the same pattern in the weight
of filled grains and yield per 5m2 except
Sapaw and
Ba-ay landraces.

SUMMARY, CONCLUSION AND RECOMMENDATION
Summary
The study was conducted from September 2009 to March 2010. Nine landraces of
rice were evaluated to identify the best rice landraces with the highest yield and
resistance to pests and to determine the profitability of growing the non-glutinous rice
landraces under Bineng, La Trinidad, Benguet condition.
The performance of the nine rice landraces during the seedling stage showed
normal and vigorous seedlings.
Sapaw had significantly taller seedlings before
transplanting.
Among the landraces evaluated,
Sapaw and
Ba-ay produced the highest number
of filled grains and unfilled grains, heaviest weight of 1000 grains, and total yield per
hectare.
In terms of the vegetative data,
Sapaw was the tallest during seedling and maturity
stages but was the latest to boot from transplanting.
Kayamsing was the earliest to produce tillers and produced the lowest number of
unfilled grains.
In terms of resistance to stem borer and blast, all of the rice landraces were
resistant while most of the landraces were damaged by rats except for
Sapaw and
Ba-ay.
Conclusion
Based on the results,
Ba-ay and
Sapaw are the best performing landraces and
considered to be adapted at Bineng, La Trinidad, Benguet because both produced the
highest yield, positive ROCE and showed resistance to neckrot, blast and rat damage.

Recommendation
Based on the results and observations of the study,
Ba-ay and
Sapaw are the
landraces recommended for rice growers of Bineng, La Trinidad, Benguet.
Makaneneng
and
Bayag yielded slightly lower than
Ba-ay landrace but both maybe considered by
farmers as alternative landraces due to their neckrot and blast resistance.
