Morpho-agronomic characterization of Indian soybean for grouping and varietal protection

Published on

Eighty-six soybean varieties differing for various
morphological characters were characterized for DUS traits
during the kharif seasons from 2007 to 2010 to protect
these varieties under Protection of Plant Varieties and
Farmers Rights Act (PPV&FRA) 2001. Results of their PCA
revealed that days to 50 % flowering, plant height and nodes
per plant traits accounted for the most variability. The
cluster analysis grouped 86 varieties in to 13 groups. The
present study proposes sets of hybridization between the
high and low mean yield clusters to achieve yield gain in
soybean.

Keywords: Cluster analysis, DUS traits, genetic variability, PCA
