Abstract

Studies on the g × e interaction of varieties and hybrids using the model of Perkins and Jinks (1968) indicated that the linear component of the g × e interaction was greater in the parents than in the F1 hybrids. The F1 hybrids were generally characterized by higher mean performance and higher slopes than the mean of their respective parents indicating that heterosis is generally associated with greater sensitivity to the environment.
