ABSTRACT
Twenty four hybrid combinations derived by crossing six arboreum lines with four arboreum testers were tested along with their parents including two checks. The observations on thirteen yield attributing characters were recorded on randomly selected five plants. Among ten parental lines, four lines were found to be the best general combiners which had significant GCA effect for seed cotton yield. The results revealed that, hybrids developed from PA 734 X PA 528 was found to be the best combining ability which had significant SCA effect for seed cotton yield. The ratio of б2 gca : б2sca variance for general and specific combining ability was less than unity for the characters except seed cotton yield per plant indicating preponderance of non additive gene action for seed cotton yield and component charecters. Based on mean performance, female lines PA 743 and PA 713, male parents (tester) PA 255 and PA 528 and hybrids PA 760 x PA 255, PA -760 X PA 08 were found best for seed cotton yield. The parental lines PA 760, PA 713, PA 08 and PA 255 were found as best general combiners for seed cotton yield per plant and other yield contributing characters and fibre quality traits.The hybrids viz., PA 734 x PA 528 and PA 760 x PA 255 were found best specific combiner for seed cotton yield per plant and other yield contributing characters.
Key words: Cotton, GCA, SCA, Line x tester analysis.
