Improvement and Selection of Gamma-ray Treated Beans
This work was performed at Sids Horticulture Research Station, Agriculture Research Center, Egypt, during the period from 2016 to 2017 to study the influence of gamma rays on growth and productivity in two generations (M1 and M2) of two bean (Phaseolus vulgaris L.) cultivars under normal growing conditions to improve the crop. Seeds of two commercial cultivars (Nebraska and Paulista) were subjected to five different potions of gamma rays i.e., 25, 50,100, 150 and 300 Gy from cobalt–60. Significant differences between irradiated and non-irradiated plants were detected for most of the studied characters in the M1 and M2 generations. The seeds of both Nebraska and Paulista cultivars germinated up to 100 and 150 Gy doses, respectively. Days to germination decreased significantly at 25 Gy followed by 50 and 100 Gy as compared to control for both cultivars (with no significant differences among them in Paulista). The doses 50 and 25 Gy along with control treatments were the highest for germination percentage for both cultivars with no significant differences among. Individually selection procedure was applied in the second generation. Four promising lines were selected i.e., NB-4, NB-9, NB-2 and NB-7 from Nebraska cv and five promising lines PS-4, PS-9, PS-10, PS-6 and PS-1 from Paulista population. Correlation studies generally indicated that plant height, branches per plant, both length and thickness of pod, seeds per pod, weight of 100-seeds, both
