Standard heterosis for yield and its attributing traits in brinjal (Solanum melongena L.)

Abstract

The study of heterosis is a basic prerequisite for the exploitation of transient hybrid vigour. Six phenotypically diverse parents were used for hybridization following half diallel mating design to obtain fifteen hybrids. Evaluation of hybrids along with the parents and standard check (GAOB-2) was conducted followed by randomised complete block design with three replications. The analysis of variance revealed that considerable genetic variation was present among genotypes, parents and hybrids for all characters under investigation. With regards to per se performance, AB-08-14 and AB-08-14 × GBL-3 registered the highest per se performance for yield attributing traits. Among 15 hybrids, significant and positive standard heterosis was observed in 11 hybrids for fruit yield plant-1 and the highest standard heterosis (%) for fruit yield plant-1 was observed in AB-08-14 × GBL-3 over standard check and it can be commercially exploited after assessing their stability.
