Effect of Heterosis on Growth, Earliness and Yield Characters of Brinjal (Solanum melongena L.)

Abstract

The present study was conducted to estimate the magnitude of heterosis for thirteen characters in brinjal. The analysis of variance revealed that the genotype selected were having sufficient amount of genetic variability amongst them to carry out further genetic analysis. Forty five F1 hybrids (generated by line x tester mating design using diverse fifteen lines and three testers) along with 18 parents and standard check hybrid (Punjab Sadabahar) were evaluated in a randomized block design with three replications at The Research Farm of Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar. Highest heterotic value for fruit yield per plant was observed in cross combinations HE-100 x H-8 (42.27%) followed by HE-100 x HLB-12 (40.97%), HE-106 x BR-112 (37.54%) and HE-101 x BR-112 (36.46%). The cross combinations HE-100 x BR-112 followed by HE-100 x H-8 and HE-100 x HLB-12 showed earliness among all the crosses.
