Abstract

A study was conducted in brinjal to estimate the magnitude of heterosis for eight fruit characters. Significant heterosis exhibited by different crosses for different characters over the years viz., fruit length (PRxWB-1, PB-66xPB-67 & PB-66xWB-1), fruit diameter (PB-66xPS & BARIxPS), average fruit weight (BARIxPR, BARIxPS & WB-1xPS), number of healthy fruits/plant (S. aethiopicum xBARI & BARIxPB-66), number of infested fruits/plant (S. aethiopicum xBARI, BARIxPS & BARIxPR), weight of healthy fruits/plant (BARIxPB-66, BARIxPR & PB-71xPS) and weight of infested fruits/plant (PB-67xPS, PB-66xPR & BARIxPB-67) for almost all types of heterosis. The crosses BARIxPB-66, BARIxPR and PB-71xPS exhibited highest and significant positive heterosis over better parent, mid parent and standard checks for fruit yield over the years. The present study reveals good scope for isolation of pure lines from the progenies of heterotic F1s as well as commercial exploitation of heterosis in brinjal.
