Association of Quantitative Traits in Upland Cotton (Gossypiumhirstum L.)

The present study was conducted in experimental field of Nuclear Institute of Agriculture, Tandojam, during kharif season 2013. The plants were grown with four replication in Randomized Complete Block Design. In order to determine the association among different yield and its components traits in cotton genotypes. The observations were recorded in plant height (cm), monopodial branches plant, sympodial branches plant-, bolls plantand seed cotton yield (gm) plant. The analysis of variance depicted highly significant differences among all the genotypes for most parameters. Based on mean performance, varieties NIA-Ufaq and Chandi-95 displaced better performance in four out of five quantitative traits. While Reshmi produced tallest plants, maximum number of monopodial branches plant. The correlation results revealed highly significant and positive associations of sympodial branches plant and boll numbers plant with seed cotton yield palnt.Present finding results clearly demonstrated that cotton production could be increased by increasing boll numbers plant and sympodial branches plant 1 .Hence, these yield mechanism could be exploited potential material in future breeding programs to improve seed cotton yield.
