Combining ability and heterosis studies in grain sorghum (Sorghum bicolor (L.) Moench).

Abstract: This study was carried out to study heterotic response and combining ability in grain sorghum crosses .

Thirty exotic cytoplasmic male sterile lines (CMS) and two restorer lines viz. Local 129 as tall variety and NES 1007 as short dual purpose variety , were sown at Shandaweel Research Station (Sohag) in 1994 season. The thirty CMS lines were top crossed with the two restorers to develop 60 top crosses (thirty with Local 129 and thirty with NES 1007). These top crosses along with the two restorer lines were evaluated in completely randomized block design with three replications at Assiut Agriculture Research Farm Assiut University and Sohag (Shandaweel Research Station) in 1995 season.
Data were recorded on days to 50 % blooming , plant height, leaf area, panicle length, panicle width, 1000 grain weight and grain yield. The collected data were statistically analyzed for each location and over both locations. Also the combining ability was estimated from the line × tester analysis and the correlation among pairs of traits were estimated
