The research was conducted in experimental area of Department of Plant Breeding and Genetics, University of Agriculture, to investigate correlation among different yield and fibre characteristics which are the dire need of growing textile industry. Five parent genotypes and their 10 hybrids were under research study. Their heritability, genetic advance, correlation and path coefficient analysis successfully performed. Yield and fibre conducing traits had high heritability. Broad sense heritability was highest for fibre strength followed by sympodial branches and plant height. Genetic advance was highest for plant height, than for GOT and fibre strength. Seed cotton yield showed significant positive correlation with plant height, number of bolls, sympodail branches and fibre length. Direct positive effects of GOT, plant height, fibre length and fibre strength on seed cotton yield. Fibre fineness showed negative correlation and also had negative effects on seed cotton yield. Plant height, GOT and fibre strength have direct positive effect on seed cotton yield, whereas, 100 seed weight, number of bolls and fibre length can divert selection procedure due to high environmental effects.
