BOLON, GLORY ANN A. APRIL 2010. Adaptability of AVRDC Soybean
Accessions Under Guinaoang, Mankayan, Benguet. Benguet State University, La
Trinidad, Benguet.
Adviser: Belinda A. Tad-awan, Ph.D.
ABSTRACT

Adaptability trial of ten AVRDC soybean accessions was conducted at
Guinaoang, Mankayan, Benguet to identify the best accession/s based on yield and
resistance to insects and diseases.

The AVRDC accessions had early emergence, flowering, pod setting and maturity
as compared with the local check, ‘Ifugao’. AGS 435 produced the tallest plants at 30
days after planting.
The local check, ‘Ifugao’, produced the highest number and heaviest weight of
marketable pods, and one- two- and three-seeded pods, however, it produced the
narrowest and shortest pods.

Among the AVRDC accessions, AGS 436 produced the highest marketable, total
and computed fresh pod yield.

High resistance to soybean pod borer and soybean rust was noted in all the
accessions.


As to sensory evaluation of green pods, all the accessions were slightly aromatic
except for AGS 440 which was moderately aromatic. All accessions are acceptable by the
farmers except for ‘Ifugao’ which was disliked moderately.

INTRODUCTION


Soybean (Glycine max) is an annual warm season crop and short-day plant. It can
withstand brief periods of drought and flooding. Soybean can be grown as an upland crop
where most production occurs in areas where normal rainfall provides the entire moisture
supply for the crop. Soybeans introduced from geographical zones of high latitudes have
been observed to produce a good plant type during wet season (Lantican and Garaza,
1977).
Soybean is grown in the Philippines even it is not a native crop. Excellent
soybeans in experiment plots and in farmers’ field were observed and yield reported by
farmers are in line with yield obtained in soybean production on areas over the world
(Smith, 1971).
Soybean is highly nutritious food for both children and adults. It is cholesterol
free, has high protein content and has been found to contain substances such as
isoflavones and gnistein that helps prevent cancer (PCCARD, 2002).
With the importance of soybean, it is therefore necessary to expand its cultivation
in other areas like the Philippine highlands. However, to expand production, adaptation
trials of different accessions should be conducted.
The study aimed to evaluate the adaptability of different soybean accessions
acquired from AVRDC and to identify the best soybean accession/s based on yield and
resistance to insect and diseases under Guinaoang, Mankayan, Benguet condition.
The study was conducted at Guinaoang, Mankayan, Benguet from November
2008 to March 2009.

REVIEW OF LITERATURE


Adaptation of Soybean


The environmental adaptation of soybean is similar to that of corn. The crop is
grown from latitudes of 0 to 55oC. However, management practices and cultivar selection
and the concentration of commercial production vary considerably across those latitudes.
In tropical latitudes, soybean is grown from below sea level to 2,000 m altitudes. The
variation in environmental conditions for this latitude and altitude range illustrates the
adaptability of soybean to different environmental conditions. The major commercial
production of soybean is between 25o to 45o latitude at altitudes of less than 1,000 m
(Bishop, 1983).
Soybean can be grown as an upland crop in 7 to 8 months of natural rainfall in
the Philippines. In the potential areas of soybean production, the first crop maybe planted
at the onset of the southwest monsoon starting in June. During this season, rainfall is
usually high, day length goes beyond 12 hours and light quality is much affected by
persistent cloud cover. This period is commonly referred to as the “wet” season. The
second crop maybe planted on October. Precipitation is less intense, temperature is lower
and day length is less than 12 hours: the dry season (Lantican and Garaza, 1977).
During the dry season, the trend of adaptation between the tropical and introduced
groups of soybeans is usually reversed. The tropical types tend to be more adaptive and
high yielding whereas the counterparts from high latitudes do not attain sufficient
vegetative development to ensure high yield (Lantican and Garaza, 1977).

Germplasm Collection and Varietal Evaluation
Soybean improvement programs in the USA, Canada, Brazil, Japan, Taiwan, and
Africa now have resources of hybridization and selection larger than has been possible
hitherto. These programs emphasize the importance of collecting, exchanging,
introducing and maintaining germplasm to provide a wide range of genetic diversity for
plant breeders to exploit (Shunmugasudaram, 1979).
Several authors have discussed the merits of using photoperiod and sensitive
cultivars, particularly in areas of the tropic and subtropic were more than one soybean
can be grown per year (Hinson, 1974, Shunmugasudaram, 1981). Such genotypes are
now available and could presumably incorporated in varietal improvement programs
(Summerfields, 1981).
Morphological characterization and evaluation done by Doco (2009) at La
Trinidad, Benguet revealed that AGS 437 and AGS 439 produced the highest fresh pod
yield among the AVRDC accessions. Moderate to mild resistance to pod borer, cutworm,
and leaf miner and high resistance to leaf blight were also noted in the same study.
The study of Menzi (2009) on adaptability and acceptability conducted at Pacso,
Kabayan showed that AVRDC soybean accessions specifically AGS 439 and AGS 433
produced the widest, longest and heaviest pods among the AVRDC accessions. Mild to
moderate resistance to soybean rust and leaf miner were observed.
Adaptability and acceptability trial conducted at Gambang, Bakun (Wa-ilen,
2009) showed AGS 438 was the best performer among the AVRDC soybean accessions
producing the highest number, widest, longest and heaviest of one-two and three- seeded
pods. Green pods of all the accessions were found to be acceptable by the farmers.

Cultural Management Practices

Mushroom compost was applied at the rate of 5 kg per 5 m2 two weeks before
planting. Vermicompost was applied at the rate of 15 kg per 160 m2 during the vegetative
stage.
Cultural management practices like weeding and irrigation were uniformly
employed.

Data Gathered:
1. Agro Climatic data. Air temperature (oC), relative humidity (percentage), and
rainfall (mm) were recorded during the conduct of study.
2. Maturity
2.1. Number of days from sowing to emergence. This was recorded by
subtracting the date of sowing from the date of emergence when at least 50% of the
plants have fully emerged.
2.2. Number of days from emergence to flowering. This was recorded by
counting the number of days from emergence to the day when 50% of the plants have
flowered.
2.3. Number of days from emergence to pod setting. This was recorded by
counting the number of days from emergence until the days when the pods are developed.
2.4. Number of days from emergence to first harvest. This was recorded by
counting the number of days from emergence until the days when pods are ready to
harvest.
2.5. Number of days from emergence to last harvest. This was recorded by
counting the number of days from emergence until the day last harvest was done.

3. Stem characters
3.1. Initial plant height (cm). This was measured from the base of the plant at
ground level to the tip of the youngest shoot, using a meter stick from five sample plants
per plot at 30 days after planting.
3.2. Final plant height (cm). This was measured from the base of the plant at
ground level to the tip of the youngest shoot, using a meter stick from five sample plants
per plot.
3.3. Number of nodes per plant. This was recorded by counting the number of
nodes of five sample plants on the main stem.
4. Pod Characters
4.1. Pod color. This was observed during harvesting using the following pod
color rate:
Scale Description
1 Dark
green
2 Green
3 Yellow
green
4 Yellow

4.2. Number of one-seeded and two-seeded pods per five plants. This was
taken by counting the one-seeded pods using the same five plants where the pods were
stripped.
4.3. Weight of one-seeded and two-seeded pods per five plants (kg). This was
taken by weighing the one- seeded and two-seeded pods after counting.

4.4. Length of one-seeded and two-seeded pods (cm). This was taken by
randomly selecting filled pods from the stripped pods of the sample plants and measured
from end to end using a foot rule.
4.5. Width of one-seeded and two-seeded pods (cm). This was measured by
measuring the width of the same pods which was measured for pod length using a foot
rule.
5. Yield and Yield Components
5.1. Weight of marketable fresh pod per plot (kg). This was recorded by
weighing the marketable fresh pods per plot of each treatment. Marketable pods are free
from disease and insect damage and not deformed.
5.2. Weight of non-marketable fresh pod per plot (kg). This was obtained by
weighing the non-marketable pods per plot of each treatment. Non-marketable pods were
observed as diseased, damaged and deformed.
5.3. Total pod yield per harvest plot (kg). This was recorded by getting the total
weight of marketable and non-marketable fresh pods per plot of each treatment
throughout the harvesting period.
5.4. Computed fresh pod yield (t/ha). Total yield per hectare in tons was
computed using the following formula
Yield (t/ha) = total yield per plot x 2

Where 2 is the factor to be used to convert yield in kg/5m2 ton per hectare
assuming it is one hectare effective area.

RESULTS AND DISCUSSION


Meteorological Data During
the Conduct of the Study

Table 1 shows the temperature, relative humidity and amount of rainfall during
the conduct of the study. Temperature ranged from 14oC to 26oC. Mean relative humidity
was 73.5 %. Rainfall amount recorded was 80.25ml, which occurred only in November.
Soybean grows best in areas with 10oC to 40oC although it can be grown in most
agro-climatic regions but preferred areas are dry zone (Bishop, 1983).

Maturity

Days from sowing to emergence. Significant differences were observed among
the AVRDC accessions on the number of days from sowing to emergence. AGS 437 and
AGS 434 were the earliest to emerge at eight days while the rest of the accessions
emerged at nine days after sowing (Table 2).
Days from emergence to flowering. Highly significant differences were observed
among the accessions as shown in Table 2. Among the ten accessions tested, AGS 438

was the earliest to flower at 35 days after emergence. ‘Ifugao’ was the last to flower at 47
days after emergence.
The same result was found by Doco and Menzi (2009) that days from emergence
to flowering ranged from 34 to 47 days in La Trinidad and Kabayan, respectively.
Days from flowering to pod setting. Significant differences were noted among the
AVRDC accessions (Table 2) on the number of days from emergence to pod setting.
‘Ifugao’ was the latest to produce pods at ten days after flowering while the accessions
from AVRDC produced pods at eight and nine days after flowering.
Wa-ilen (2009) also observed that pod setting of the same accessions were seven
to eight days after flowering under Bakun, Benguet condition.
Days from emergence to first harvest. No significant differences were observed
among the AVRDC soybean accessions on the number of days from emergence to first
harvest. First harvesting was done on AVRDC accessions at 71 to 72 days after
emergence. This result confirms with the study of Menzi and Wa-ilen (2009) in Kabayan
and Bakun, respectively.
‘Ifugao’ reached the R6 stage (full seed or when pod containing a green seed that
fills the pod cavity at one of the four uppermost nodes on the main stem with a fully
developed leaf) at 79 days after emergence.
Days from emergence to last harvest. As shown on Table 2, highly significant
differences were noted among the AVRDC soybean accessions. AGS 432 and AGS 292
were the earliest to be harvested at 90 days after emergence. Wa-ilen (2009) also noted
that the same accessions were harvested at 91 and 92 days after emergence in Bakun.
Last harvesting was on ‘Ifugao’ at 102 days after emergence.

Plant Height and Growth Pattern

Plant height at 30 and 60 DAP. Table 3 shows the height of the plants at 30 and
60 DAP. AGS 435 was measured to be the tallest (14.61cm) at 30 DAP but comparable
with AGS 433 and AGS 438 at 13.95 cm and 13.54 cm, respectively. Significant
differences on final plant height varying from 15.30 cm to 23 cm were recorded with
AGS 439 as the shortest and ‘Ifugao’ the tallest.

The study of Menzi and Wa-ilen (2009) also showed that ‘Ifugao’ produced the
tallest plants.

The results confirm the findings of Lantican (1987) that introduced varieties
generally lack the necessary height, produce limited amounts of vegetative parts and
flower very early, consequently producing poor yields. Temperate varieties generally
have limited use during dry season especially if seed for planting were imported from
their place of origin.

All the accessions have determinate habit of growth.

Number of Nodes per Plant

Highly significant differences were observed on the number of nodes per plant.
‘Ifugao’, AGS 433, AGS 435 and AGS 436 were recorded to have the highest number of
nodes but comparable with AGS 438, AGS 432, AGS 439 which have the least number
of nodes among the eleven soybean accessions evaluated.

Doco (2009) also observed that ‘Ifugao’ had the highest number of nodes and
AGS 439 had the least number of nodes under La Trinidad, Benguet condition.

Pod Characters
Pod color. All the AVRDC accessions exhibited green pods. ‘Ifugao’ has yellow-
green pods.

Menzi and Wa-ilen (2009) noted the same pod color. However, Doco (2009)
observed dark green pods of ‘Ifugao’.

The result of the various studies on soybean accessions confirm the statement of
Shanmugasundaram (1990) that pod color is highly influenced by the environment.

Number of One-,Two-,and Three-Seeded Pods

Highly significant differences were observed among the number of one-two-and
three-seeded pods (Table 4).
‘Ifugao’ exhibited the highest number of one-two-and three-seeded pods at 553,
775 and 117, respectively. All the AVRDC accessions were not significantly different
from each other.

Numerically, the highest number of one-seeded pod was obtained from AGS 437
and two-seeded pod was obtained from AGS 436.

Doco and Menzi (2009) also reported that ‘Ifugao’ produced the highest number
of pods in La Trinidad and Kabayan, respectively. However, Wa-ilen (2009) found that
AGS 438 produced the highest number of one-, two- and three-seeded pods among the
AVRDC soybean accessions in Bakun.

Length of One-, Two-, and Three- Seeded Pods

‘Ifugao’ had the shortest one-two-and three seeded pods (Table 5). AGS 433 was
noted to have the longest one-seeded pods at 4.24 cm while AGS 438 was recorded to
have the longest two-seeded pods but did not significantly differ from AGS 434, 439 and
440. Accessions AGS 433, AGS 434, AGS 438, AGS 439 and AGS 440 were recorded to
have the longest three-seeded pods.

Width of One-, Two-, and Three- Seeded Pods
‘Ifugao” had the narrowest one-two-and three-seeded pods at 1.38, 1.39, and 1.38
cm, respectively. The widest one-seeded pod was recorded from AGS 435 and AGS 438
both measuring 1.67 cm. The other accessions have comparable pods (Table 6).

AGS 435 was measured to have the widest two-seeded pods but comparable with
the other accessions. AGS 292 has the widest three-seeded pods measuring 1.66 cm but
comparable with the other accessions.

Reaction to Pests and Diseases
Reaction to pod borer. No infestation of pod borer was observed among the
accessions. However, Doco (2009) reported mild to moderate resistance to pod borer of
the AVRDC accessions under La Trinidad, Benguet condition.
In Japan, the genotypes with glabrous or curly pubescent types were reported to
be resistant to soybean pod borer, but were susceptible to potato leaf hopper (Bernard and
Weiss, 1973).

Reaction to soybean rust. No infestation of soybean rust was noted in all of the
accessions. The same case was noted by Wa-ilen (2009) in Bakun, however, Menzi
(2009) noted mild to moderate resistance to soybean rust in Kabayan, Benguet.
As reported by PCCARD (1986) soybean rust favors cool temperature and high
humidity.

Reaction to Lodging

All the accessions were resistant to lodging. This could be accounted to the short
stature of the plants.
Factors such as high plant population, high soil moisture, and high soil fertility
can stimulate vegetative growth and increase plant height, leading to lodging. As plant
populations increase, soybean stems become longer and more slender and plant
standability decreases (Klein and Elmore, 2000).

Sensory Evaluation

Samples of newly harvested pods were blanched and were evaluated by 10
farmers, 10 students and 10 faculty members.

AGS 440 was rated moderately aromatic while the rest of the accessions were
rated slightly aromatic. Based on the acceptability test, all the accessions from AVRDC
were moderately liked while ‘Ifugao’ was disliked moderately. This could be due to the
fact that ‘Ifugao’ is being cultivated for grain and not as vegetable soybean (Table 9).

For sensory evaluation of fresh pod yield, consumers are considering the color
and width of the fresh pods. Apparently, green to dark green and wide fresh pods area
acceptable in addition to their aroma (Pog-ok, 2001).

SUMMARY, CONCLUSIONS AND RECOMMENDATIONS

Summary

This study was conducted at Guinaoang, Mankayan, Benguet to evaluate the
adaptability of different soybean accessions and identify the best soybean accession/s
based on yield and resistance to insect pest and diseases under Guinaoang, Mankayan,
Benguet.

The study showed significant differences among the AVRDC soybean accessions
and ‘Ifugao’ on the number of days from sowing to emergence, emergence to flowering,
flowering to pod setting, emergence to last harvest, plant height, number of nodes,
number, length and width of one-two and three-seeded pods, and pod yield.
Results showed that the accessions from AVRDC exhibited early emergence,
flowering, pod setting and maturity. AGS 435 was noted to have the tallest plants at 30
days after planting while ‘Ifugao’ recorded the tallest plants at 60 days after planting. It
also produced the highest number and heaviest weight of one-, two and three-seeded
pods, marketable, total and computed fresh pod yield.

Among the AVRDC accessions, AGS 436 produced the highest marketable, total
and computed fresh pod yield. As for the sensory evaluation of boiled green pods, all the
accessions from AVRDC were acceptable while ‘Ifugao’ was disliked moderately. All
the accessions were slightly aromatic except for AGS 440 which was moderately
aromatic.
All the accessions showed high resistance to soybean rust, pod borer and lodging.

Conclusions

The best among the AVRDC soybean accessions based on marketable, total and
computed fresh pod yield is AGS 436. All the accessions are resistant to pod borer and
soybean rust.

Although ‘Ifugao’ produced the highest pod yield, it is not intended for vegetable
soybean production but for grain production.

Recommendations

AGS 436 can be recommended as vegetable soybean in Guinaoang, Mankayan,
Benguet.

Due to low yield obtained during the conduct of the study it is recommended that
further studies should be conducted under different planting dates.
