Forty eight brinjal hybrids were evaluated along with their sixteen parents and a check variety (GBH 1) for fruit borer infestation and fruit yield per plant during three consecutive seasons (environments) viz., kharif-2003 (E₁), rabi-summer-2003 (E₂) and Summer-2004 (E₃). The stability analysis indicated that significant G x E interactions for both the attributes revealed that the genotypes had linear response to environmental change, while significant pooled deviation suggested that deviation from linear regression also contributed substantially towards the differences in the stability of genotypes. Further, linear and non-linear components contributed significantly to the differences in stability among the genotypes tested. From the point of view of yield and resistance to fruit borer infestation, six hybrids viz., JBSR 98-2 x Pant Rituraj, ABL 98-1 x Pant Rituraj, ABL 98-1 x GBL 1, Morvi 4–2 x GBL 1 Morvi 4–2 x PLR 1 and Green Round x GBL 1 were identified as most widely adapted hybrids on the basis of stability parameters viz., overall mean (), regression coefficient (bi) and least deviation from regression (S²di). Thus, these hybrids could be used either for resistance breeding or be exploited for commercial exploitation of hybrid vigour in brinjal.
