Identification of heterobeltosis for quantitative traits in mungbean

Abstract

Diallel analysis was performed using ten mungbean genotypes and their 45 F1 hybrids. The experiment was laid down in Randomized Block Design (RBD) with three replications during kharif 2012 at Centre of Excellence for Research on Pulses, Sardarkrushinagar Dantiwada Agriculture University, Sardarkrushinagar, Gujarat. The observations were recorded both as visual assessment (days to flowering and days to maturity) and measurement on randomly selected five competitive individual plants (plant height, number of branches per plant, pods per plant, pod length, seeds per pod, 100-seed weight, seed yield per plant and protein content). The hybrid K 851 x Meha, registered significant positive heterobeltiosis for seed yield per plant. Heterosis in seed yield per plant was reflected mainly through component trait pods per plant.
