Summary

Genotype-environment interactions have been studied in parental, F₁, and segregating generations (F₁, F₂) of four crosses between Indian and Mexican varieties. Presence of genotype-environment interactions was revealed. The linear component appeared to be accounted for most of the interactions present. Hence, mean performance of the varieties could be predicted across the environ ments. In case of grain yield, the F₁’s were found to be more responsive than ten segregating generations. The mean performance appeared to be associated with linear component of genotype-environment interactions, whereas no such relationship of non-linear component with mean performance as well as regression coefficients was evident.
