| Abstract | ||||
| Twenty five F1 grain sorghum crosses, its parents (five female lines and five male lines) and one commercial hybrid (Shandaweel-6) as check were evaluated for yield and four other characters in 2010 and 2011 seasons at Shandaweel Res. Station under two levels of irrigation (100% and 40% ET). The obtained data showed significant or highly significant differences between years, irrigation treatments and among genotypes for all studied traits except between years for 1000-grain weight. The interactions years × genotypes, irrigation × genotypes and year × irrigation × genotypes were highly significant for all studied traits except for No. of green leaves. Also, the interaction years × irrigation was significant for plant height and 1000-grain weight. Highly significantdifferences among crosses, and parents for all studied traits were obtained in two seasons, except for No. of green leaves in 2011 season. Mean squares due to parents vs. | ||||
