This investigation aimed to study the stability and performance of 30 sorghum genotypes across 8 environments. Twenty grain sorghum crosses and five introduced cytoplasmic male sterile lines (CMS-lines), four restorer lines (R-lines) and hybrid H-305 as the check were evaluated at eight environments i.e.; two years (2016 and 2017), two locations (Shandaweel Agric. Res. Station, Sohag Governorate and Arab El-Awamer  Agric. Res. Station, Assiut Governorate ) and two planting distances 20 (D₁) and 15 (D₂) cm between hills.The combined analysis of variance of 30 genotypes over eight environments appear highly significant differences among genotypes and environments for all studied traits.Moreover, the genotypes × environments interaction variance was also highly significant for all the studied traits, evidence that genotypes responded differently to environmental factors. Most crosses were earlier and heavier in 1000 grains weight, taller and higher in grain yield per plant than best parents over eight environments. In addition, decreasing planting distances from 20 cm to 15 cm decline in plant height,1000 grains weight and grain yield/plant. While, decreasing planting distances from 20 cm to 15 cm  led to increasing in days to 50% flowering. The joint regression analysis showed highly significant differences between genotypes and between environments, as well as significant genotype x environment interactions, indicating differential responses to changes in environment for the studied traits. The G × E interactions were linear functions to the environment, which were significant for all studied traits, except plant height. The stability parameters (b_i and s²d) for grain yield per plantshowed that the genotypes varied in their (b_i) values as well as S²d.It could be noticed that the regression coefficient (b_i) for genotypes (A SH-21×R SH-76), (A SH-16×R SH-76), (A SH-10×R SH-10), (A SH-16×R SH-10), (A SH-10×R SH-37), (A SH-14×R SH-37), (A SH-21× ICSR-92003), (A SH-28×ICSR-92003) and (R-SH-10) were insignificant from unity and the deviation from regression (S²di) were insignificant from zero indicating that these genotypes considered to be stable for grain yield per plant. Seven genotypes had significant higher grain yield per plant than the grand mean (A SH-21×R SH-76), (A SH-10×R SH-10), (A SH-16×R SH-10), (A SH-10×R SH-37), (A SH-14×R SH-37), (A SH-21× ICSR-92003) and (A SH-28×ICSR-92003).
