dc.description.abstractIn recent years cotton breeders have started to interest more and more attention for improving high temperature tolerant cotton varieties due to increased global warming. For this purpose54 cross combinations (6x9) were created in 2010 and 54 F1 hybrid and their 15 parents, totally 69 genotypes were tested at the experimental area of GAP International Agricultural Research and Training Center in 2011. In the populations seed cotton yield, ginning percentage, fiber yield, photosynthetic yield, chlorophyll content and photosynthetically active radiation expressed non-additive gene action (dominant or epistatic) and GCA variance was higher than SCA variance only for fluorescence reflecting the role of additive type of gene action. It was determined that SJ-U86, AGC 375, Fiber Max 819, AGC 208 and STV 453 for seed cotton yield; Fiber Max 819 and Fiber Max 832 for ginning percentage; SJ-U86, DP 90, AGC 375, Fiber Max 819 and STV 453 for fiber yield; Fiber Max 832 and STV 453 for photosynthetic yield; AGC 375, SJ-U 86 and DP 396 for chlorophyll content; Fiber Max 819 and STV 474 for fluorescence; AGC 208 and DP 499 for photosynthetically active radiation (PAR) were the best parent cotton varieties and also having the best (GCA) general combining abilities. In the study specific combining ability (SCA) of hybrids were investigated and some promising cross combinations were selected and transferred to the next generation.en_US
