Abstract:
The present investigation was undertaken at Botany division, College of Agriculture, Pune during rabi season in Randomized Block Design with 3 replications for 16 genotypes of French bean for twelve quantitative traits, based on the stability parameters using Eberhart and Russel model to assess seed yield potential for different genotypes under three different sowing dates viz. E₁ (15/10/2021), E₂ (5/11/2021) and E₃ (25/11/2021). Based on mean performance of genotypes under study showed differential stability performance for all the twelve characters, indicated that Raj-20-8 had least number of days to 50 percent flowering (36.33 days). Genotype Phule Rajmah recorded the maximum number of pods per plant (14.84). Genotype Phule Rajmah (5.27) and Varun (5.02) had recorded maximum mean number of seeds per pod. Highest number of seed per pod (4.16) recorded in E3 environment over all three environments followed by E2 (4.14) and E1 (4.04). Genotype GRB- 912 (38.32) had highest 100-seed weight. Genotype Phule Rajmah was found highest harvest index (65.38) followed by EC-21754 (62.00). Genotype P. Rajmah (9.31 cm) had longest pod length followed by Varun (9.25 cm) and shortest in Shimla-1 (7.63). The maximum mean seed yield per plant was observed in Phule Rajmah (24.80) followed by GRB-910 (23.83). Across all the three environment mean seed yield per plant was greater in E3 (16.32 g) followed by E2 (15.78 g) and E1 (15.34 g) environment. On the basis of results obtained in present investigation sowing of French bean under environment E3 (25^th November) was most favorable for most of the characters under study, during rabi season.
