Heterosis for fruit yield in diverse Brinjal (Solanum melongena L.) germplasm
Publication Date : 29/07/2016
With prime objective of developing season/region specific hybrid, the present investigation was undertaken to obtain the information on the heterosis for fruit yield in brinjal (Solanum melongena L.) using line x tester analysis. The experimental material comprised of ten lines, four testers and resultant 40 hybrids along with two checks which were raised in a randomized block design with three replications in three environments (different seasons) viz., Late Kharif, Rabi and Early Summer at Navsari during 2014-15. The degree of heterosis varied from cross to cross for fruit yield per plant. Considerable heterosis in certain crosses and low in other crosses revealed that nature of gene action varied with the genetic architecture of parents. Fourteen crosses over check ABH – 1 and thirty one crosses over check Surati Ravaiya, reported significant and positive standard heterosis for fruit yield per plant which appeared to be due to the diversity among the parents involved. The maximum standard heterosis for fruit yield per plant over both the checks was recorded by the cross combination JB-12-6 X PLR-1. Rigorous testing of superior crosses identified through this experiment in an array of environments/season may further be performed before its commercial exploitation.
