In this paper we explored the environmental effects i.e. locations, on grain yield, popping expansion and the number of grains per 10 g. Twelve ZP popping maize hybrids were sown over three locations by the method of complete random block design. The effect of the genotype-hybrid and the location were highly significant for all three examined traits, while the hybrid x location interaction was highly significant for grain yield and the number of grains per 10 g. This indicates that grain yield, popping volume and the grain size (which is determined by the number of grains per 10 g) are not determined only by the genetic factors, but also by the environment and the genotype x environment interaction. Estimates of the rank correlation coefficients implied that there was a negative correlation among all three traits. Although these estimates were not statistically significant, they indicated that it was not easy to make high yielding and good quality popping maize hybrids.
