Genetic variability and character association among vegetable soybean genotypes for yield and components traits

S. AKKAMAHADEVI, G. T. BASAVARAJA

Abstract


Seveenteen vegetable soybean genotypes were evaluated for eleven characters at the Main Agricultural Research
Station, University of Agricultural Sciences, Dharwad during kharif 2015. Analysis of variance revealed significant differences
among the genotypes for all the traits. The phenotypic variance was higher than the corresponding genotypic variance for
all the characters. All the characters exhibited moderate to low phenotypic and genotypic coefficient of variation. Genotypic
coefficient of variation was the highest for100 seed weight (22.91%). All the traits except green pod yield (49.3%) had the
highest heritability. Number of branches per plant, number of pods per plant, number of pods per plant, hundred seed
weight, sugar and oil content revealed significant positive genotypic and phenotypic correlation with green pod yield. In
path analysis, plant height, number of branches per plant, number of pods per plant, hundred seed weight, protein and oil
content exhibited positive direct effect on green pod yield. Considering genetic variability, correlation and path analysis,
emphasis should be given on plant height, number of branches per plant, number of pods per plant and hundred seed weight
during selection to improve green pod yield of soybean.
