Combining ability and gene action for yield and yield contributing traits was studied in 13 parental genotypes (5 lines, 8 testers) in a line x tester scheme during rabi, 2017-18. The purpose of the study was to identify and select superior parents and best hybrid combinations on the basis of estimates of general and specific combining abilities. | Combining ability and gene action studies for grain yield and yield contributing traits in wheat Triticum aestivum L.
