Online published on 2 January, 2017. Abstract With prime objective of developing season/region specific as well as stable hybrid of brinjal (Solanum melongena L.), the present investigation wasundertaken to obtain the information on stability parameters for fruit yield and its components using stability 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 analysis of variance for phenotypic stability indicated genotypes x environment (G x E) interaction was highly significant for most the characters when tested against pooled error and pooled deviation. It revealed that genotypes interacted significantly to diverse environments. The importance of both linear and non-linear components in determining total G x E was revealed. The parents JBG-10-208, PLR-1 and AB-8-6; and hybrids JB-12-6 X PLR1, AB-7-2 XPLR-1, JBL-12-8-1-1 X Pant Rituraj, JBCL1 X PLR-1 and AB-7-2 X Pant Rituraj were identified as stable hybrids with wider adaptability over environments and high mean performance over general mean for fruit yield per plant and yield contributing traits. Rigorous testing of superior crosses identified through this experiment in an array of environments/season may further be performed before its commercial exploitation.
