Stability of Brinjal hybrids against fruit borer infestation in Gujarat

Abstract

Forty-eight Brinjal hybrids were evaluated along with their fourteen parents for fruit borer infestation at three different locations (environments) of Sardarkrushinagar Dantiwada Agricultural University; located in three different districts, during late rabi 2021-22 in RBD. The significant G × E interactions for fruit borer infestation 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 resistance to fruit borer infestation, three hybrids viz., Ph-9 × GAOB-2, ABSR-2 × GRB-5 and Arka Komal × GAOB-2 were identified as most widely adapted hybrids on the basis of stability parameters. Thus, these hybrids could be used for resistance breeding and for exploitation of hybrid vigour in Brinjal.
