Description Asia region core collection with 504 accessions
comprising 29 fastigiata, 230 hypogaea and 245 Vulgaris
types were characterized for 14 morphological
descriptors during 2000 rainy and 2000-01 post rainy
seasons at Regional Research Station Raichur and
Agricultural Research Station Kawadimatti, to asses the
morphological diversity, to study the significant
association between different traits and to know the
importance of descriptor traits in the total variation.
Frequency distribution of different descriptors indicated
that erect type followed by procumbent-1 and
decumbent-1 growth habit, alternate and sequential
branching pattern, absence of stem pigmentation,
subglabrous with one or two rows of hairs on the stem,
light green followed by dark green leaf color, almost
glabrous type of leaf surface, elliptic leaf shape, orange
flower color, presence of stem pigment, 2-1 seeded pods
followed by 2-3-1/2-1-3, slight to moderate beak and
constriction, moderate reticulation, tan followed by red
seed color dominated the core collection. The mean score
for number of seeds per pod differed significantly in all
three botanical varieties except growth habit, branching
pattern and leaf color. But mean score for all the traits
differed significantly with one or the other botanical
variety. For most of the traits wider range was observed
except flower color and leaf hairs and a significant
association was observed between growth habit and
branching pattern, growth habit and leaf color, branching
pattern and leaf color in the entire collection. Between
beak and pod reticulation, stem color and pod reticulation
in the variety fastigiata. PCOA indicated that 12 out of 14
morphological traits exhibited significant correlation with
either one of the botanical variety or with the entire
collection appearing atleast once in the first five PCOA
values. Shanon-Weaver diversity index revealed that
flower color and leaf hairyness are monomorphic in
nature. All the traits except growth habit, pod beak and
pod reticulation in fastigiata and pod beak in vulgaris
exhibited low diversity.
