Description Not Available
thorough and extensive wild germplasm
exploration survey was undertaken and 50 high yielding
candidate plus trees (CPTs) of Pongamia pinnata (L.)
Pierre from different locations from a latitudinal and longitudinal
spread between 12 410 and 22 E longitude and
77 and 84 400N latitude covering 11 locations in an
area spread of 150,000 km2 were collected for evaluating
genetic association and variability in seed and growth
characters. There were significant differences observed in
seed morphology and oil content as was in plant height,
and number of branches in the progeny trial. Plant height
and number of branches exhibited much higher values of
both phenotypic and genotypic variance than observed in
the seed characters. Among seed characters oil content
exhibited highest broad sense heritability of more than 93%
followed by seed length (90.0%). In contrast seed width
showed the second highest genetic advance of 5.64% following
the highest genetic advance of 10.15% exhibited by
oil content. Hierarchical clustering by Ward’s Minimum
Variance Cluster Analysis method showed phylogeographic
patterns of genetic diversity. K means clustering
revealed that trees from different geographic regions were
grouped together in a cluster and as were trees from the
same geographical area placed in different clusters suggesting
that geographical diversity did not go hand in hand
with genetic diversity. In addition clustering identified
promising accessions with favourable traits for future
establishment of orchards.
