| Abstract | An investigation was carried out at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during kharif 2008 to access the genetic variability, quality traits and stability among vegetable soybean genotypes. The experimental material for the study comprised of twelve vegetable soybean genotypes developed/ maintained at All India Co-ordinated Research Project on Soybean, University of Agricultural Sciences, Dharwad along with two checks viz., Himso 1563 and JS 335. Among the genotypes, strain 2000-02 recorded highest green pod yield (9408 kg/ha) and significant superiority with respect to traits viz., pod length, pod width and 100 seed weight and sugar content (91.5 mg/g) compared to checks. Check Himso 1563 recorded highest protein content (41.94 %) followed by 2000-02 (41.54%). The study revealed wide range of variability for all traits indicating the presence of sufficient variation among the genotypes. High heritability coupled with high genetic advance was observed for traits viz., plant height, days to maturity, days to 50 per cent flowering, pod length, pod width, 100 seed weight, sugar content, protein content and oil content. The association analysis revealed that green pod yield had significant positive association with 100 seed weight and sugar content at genotypic level. The organoleptic evaluation indicated that strain 2000-02 exhibited highest scores for over all acceptability compared to checks Himso 1563 and JS 335. In stability analysis, pooled ANOVA revealed significant differences among genotypes and environment for all the traits except for number of pods per plant indicating diverse nature of genotypes and environment. The G x E interaction was significant for all the traits except for number of branches per plant and green pod yield indicating differential response of the genotypes in different environments. However, on the basis of stability parameters 2000-05 was identified as stable genotype for all the characters studied except plant height across environments. |
