COMBINING ABILITY ANALYSIS IN WHEAT (Triticum aestivum L.) USING LINE X TESTER MATING DESIGN UNDER MOISTURE STRESS CONDITIONS
Year: 2026
Type: article
Abstract: The present study was conducted to assess the combining ability and gene action estimating yield and related traits in Wheat (Triticum aestivum L.) under moisture stress conditions using a line x tester mating design. A set of 7 lines and 3 testers were crossed to produce hybrids which along with their parents were evaluated under controlled moisture stress conditions and normal irrigation environments. Analysis of variance revealed significant differences among genotypes, parents, crosses, lines, testers and line x tester interactions for most traits, conforming the existence of genetic variability. The predominance of Specific combining ability (SCA) variances over General combining ability (GCA) variances suggested a greater role of non–additive gene action under moisture stress conditions. The results indicated that selection based on specific combiners and heterosis breeding could be effective for improving wheat yield under drought prone environments.
