Pearl millet (Pennisetum typhoideum L) genotypes (fourteen) were evaluated for stability of grain yield performance across (five) locations in the country. The yield ranking of the varieties varied across the locations. Mean squares due to variety x environment interaction were highly significant indicating genetic differences among varieties for linear response to different environments. Pearl millet variety IC 8206 gave the highest average grain yield (1881 kg ha-1) indicating response to only favourable environments and was less stable across the locations. Based on the parameters of stability, the local varieties were the most adaptive and stable, followed by PARC MS-4 and Ghana White. The varieties PARC MS-5 and PARC MS-6 were found suitable for growing in good environments while varieties PARC MS-2 and ICMV 96101 were suitable for poor environments.
