Abstract:
Diallel analysis over environments in bottle gourd [Lagenaria siceraria (Mol.) Standl.] was undertaken with an aim to assess the heterobeltiosis for fruit yield and its component traits. The experimental material consisted of total 36 entries which include eight parents and their 28 F₁ hybrids. The material was evaluated in a Randomized Block Design replicated thrice during three different seasons viz., late Rabi 2018-19 (E₁), Summer 2019 (E₂) and Kharif 2019 (E₃) at College farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari. The analysis of variance for individual as well as over environments revealed highly significant differences among genotypes, parents and hybrids for all the traits indicating ample amount of genetic variability among the parents and hybrids for all the traits. For fruit yield, the best performing hybrids over better parent were JBG 17-03 × JBG 17-08 (54.41%), JBG 17-07 × DBG 6 (52.05%) and JBG 17-04 × DBG 6 (45.43%) in E₁; hybrid JBG 17-04 × DBG 6 (81.31%), JBG 17-03 × JBG 17-08 (59.63%) and JBG 17-10 × JBG 17-01 (57.95%) in E₂; hybrid JBG 17-03 × JBG 17-01 (65.93%), JBG 17-07 × JBG 17-03 (52.98%) and JBG 17-06 × DBG 6 (36.57%) in E₃ and hybrid JBG 17-03 × JBG 17-08 (50.02%), JBG 17-03 × JBG 17-01 (48.38%) and JBG 17-04 × DBG 6 (48.21%) in pooled over environments.
