Studies on variability components for yield and its attributes in Brinjal (Solanum melongena L.) under hill zone of Karnataka

Thirty genotypes of Brinjal were assessed for genetic variability of eleven characters. Highly significant differences were observed among the genotypes studied. High phenotypic and genotypic coefficient of variation was observed for flowers per cluster, fruits per cluster, per cent fruit set, fruits per plant, fruit length, fruit diameter and fruit yield per plant indicating the presence of wide variability among the genotypes for different characters. High heritability in broad sense along with high genetic advance in per cent of mean was observed for branches per plant, days to first flowering, days to fifty per cent flowering, flowers per cluster, fruits per cluster, per cent fruit set, fruits per plant, fruit length, fruit diameter and fruit yield per plant suggesting that these can be improved through direct selection due to predominance additive gene action.
