Genetic variability and association analysis for green pod yield and its contributing characters in winged bean (Psophocarpus tetragonolobus L.)
Author(s): RK Yadav
Abstract: Ten genotypes of winged bean (including local accessions with a standard check variety) were evaluated for genetic variability and association analysis at Research farm of Indira Gandhi Agricultural University, Raipur during Kharif 2015. The phenotypic coefficient of variation (PCV) was in higher than the genotypic coefficient of variation (GCV). High heritability coupled with high genetic advance as percentage of mean were observed for traits like number of green pods/ plant, green seed yield / plant green pod yield/ plant and 100 green seed weight exhibited that these traits were governed by additive gene effects. Maximum positive significant phenotypic association with green pod yield/ plant was showed by green seeds/ pod (0.94) followed by green seed yield / plant (0.64), pod length (0.75) and days to pod initiation (0.41).
