Description An investigation was carried out to assess nature and magnitude of genetic variability
parameters, association and path analysis for different quantitative characters for productivity
and grain quality traits involving 208 mini core, 24 selected mini core and 16 selected
promising varieties during rabi season of 2011-12 and 2012-13 at AICSIP, UAS Dharwad.
Highly significant differences were found for all characters in mini core and selected
mini core and selected promising varieties, except for true density among promising varieties.
High estimates of PCV, GCV, heritability coupled with GAM were recorded for most of
characters except for bulk density and true density in mini core and similar estimates were
also recorded in selected mini core except for plant height, true density, seed size, seed
protein and seed amylopectin. Similarly seed yield per plot and fodder yield per plot among
selected promising varieties.
Seed yield per plant exhibited highly significant positive association with plant height,
ear head width, 100 seed weight, seed volume and seed size in mini core and selected mini
core collections and among selected promising varieties, seed yield per plot exhibited
significant positive association with ear head width, 100 seed weight and bulk density at both
levels. Path analysis revealed that, direct positive contribution of plant height, ear head width
and 100 seed weight towards seed yield per plant at both levels in mini core but only at
phenotypic level in selected promising varieties. Similarly, fodder yield and seed size had
high positive direct effects on seed yield per plot at both levels among selected mini core
collections.
Among mini core, IS-19975 was superior for seed yield per plant, similarly IS-13459
for seed protein, IS-13782 for seed amylose in selected mini core. SVD-803 for grain yield,
Phule Vasudha for seed protein, SVD-808 for seed amylose among selected promising
varieties.
