Abstract:
The study, conducted in the Rayalaseema region of Andhra Pradesh in 2022, involved the evaluation of 17 elite mutants generated through gamma irradiation of the TFB-2 field bean variety. These mutants were assessed alongside the parent variety, which served as the control group. The research employed a randomized block design, incorporating 18 different treatment combinations, each replicated twice. The findings revealed that M_5.16 exhibited the greatest plant height, while M_5.18 displayed an increased number of branches per plant. In contrast, M_5.17 exhibited a reduced time to flowering, and M_5.18 had the shortest duration to reach 50% flowering. Additionally, M_5.3 showed the shortest time for the initial pod set. Notably, mutant M_5.17 exhibited the highest fresh pod yield among the evaluated mutants.
