Abstract: Genotype x environment interaction in pearl millet [Pennisetum glaucum   (L.) R.Br.] was studied for grain yield by growing 90 genotypes consisting of 81 hybrids and 9 inbred parents at 5 locations for 2 years. Genotype x environment interaction was observed, a large component of which was accounted for by nonlinear regression on the environment means. Although the linear portion was significant, its magnitude was smaller than that of the nonlinear component indicating the significance of environmental effects on the genotypes. Six hybrids were found to be stable across the environments. They yielded above the average mean yield of all the genotypes under test, with a slope of unity and the mean square due to deviation from regression equal to zero.
