Abstract

A field investigation was undertaken in brinjal (Solanum melongena L.) during kharif season, 2017 to assess the extent of genetic variability, heritability and genetic advance for fifteen quantitative characters. High PCV and GCV values were seen for number of primary branches per plant, number of leaf prickles, fruit length, fruit circumference, fruits per plant, fruit weight, fruit yield per plant and yield per hectare indicating the less influence of environment on the traits. Estimates of high heritability and high genetic advance as per cent of mean were recorded for the characters except days to first flowering and days to 50% flowering indicating that the characters were least influenced by the environmental effects and the improvement of these characters would be possible through simple selection methods such as mass selection. High heritability accompanied with high genetic advance was observed for number of primary branches per plant, number of leaf prickles, fruit length, fruit circumference, fruit weight, fruit yield per plant and fruit yield per hectare indicating that simple selection may be effective to fix and improve such traits.Key words: Brinjal, Variability, Heritability, Genetic advance, KharifCite this ArticleJamini Saikia, D.
