Abstract:
This study aimed to evaluate the effect of γ-irradiation on growth, yield and quality parameters and induce variability in sweet potato [Ipomoea batatas (L.) Lam.] cv. Gouri. The experiment was carried out during the Kharif season of 2017 and 2018. The cuttings were irradiated with gamma rays (15, 30, 45, 60, 75 and 90 Gy) and sown in the field. Untreated cuttings were served as control. Various vegetative parameters like vine length, number of leaves, leaf width, above ground dry weight per plant, tuber diameter, dry matter content in tuber and harvest index were observed during the study period. The results suggested that vegetative parameters such as vine length at 30 and 60 days, no. of leaves, harvest index, tuber diameter, above ground dry weight were recorded lowest in irradiated plants over the control. Finally we concluded that gamma irradiation significantly affected the vegetative attributes and showed a decreasing trend by increasing the irradiation dose level.
