The aim of this investigation was to study the effect of environments (locations and years) on the fodder yields of some pearl millet genotypes to estimate the extent of genetic diversity among studied genotypes and to study the extent of association between the yield and its components. Thus, six field experiments were carried out at the Agricultural research center (ARC) (3 locations {u00D7} 2 seasons) research stations (Gemmeiza in 2015 and 2016 seasons, Shandaweel in 2015 and 2016 seasons and Sids in 2016 and 2017 seasons). Eleven pearl millet genotypes were evaluated (10 genotypes from ICRISAT+check variety shandaweel-1). Generally, mean squares of combined analysis showed that environments, genotypes and the interaction between them had highly significant effect on all traits. The highest total fresh and dry fodder yields were obtained in Sids 2016. IP 5862 genotype gave the highest total fresh and dry fodder yields. In general, the interaction between genotypes and environments was insignificant for fresh and dry fodder yields at all cuts 22 and total yield. The genotypic (vg ) variance and the phenotypic (vph) variance of total fresh fodder yield were higher than total dry yield. The heritability (h2 %) of total dry fodder yield was higher than total fresh fodder yield. Fresh fodder yield at all three cuts was highly positive correlated with total fresh and dry fodder yields
