Twenty eight single cross hybrids of maize were evaluated over eight environments for
grain yield and its components and harvest index. Significant genotype x environment
interaction was observed for all the traits during winter and monsoon seasons, except for
ear girth (both the seasons) and No. of ears/plant (monsoon season). These hybrids
performed well for grain yield in both winter and monsoon seasons and were also stable
tor ear length, but in general, were unstable for 1000- kernel weight in both the seasons.
The inbred line J-617-61-1-1-1-1 in hybrid combination performed well in both seasons.
The deviation from regression (5 a) appeared to be a more important parameter than
regression (bi) for measuring stability.
