The study was undertaken to find out the association between seed cotton yield, its component traits and fibre quality characters in upland cotton (Gossypium hirsutum L.). Fifty genotypes of upland cotton were sown in a randomized block design with three replications at the Research Area of Cotton Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar during kharif, 2020. Seed cotton yield exhibited a highly significant positive correlation at genotypic level with number of monopods (0.674), number of bolls (0.937), boll weight (0.533), seed index (0.725), ginning outturn (0.422 and 0.326), fibre length (0.587), fibre uniformity (0.560) and fibre strength (0.380). It showed non significant correlation with days to 50 per cent flowering and fibre fineness. There was a strong association of fibre length with fibre uniformity ( 1.007) and fibre strength (0.686) at both genotypic and phenotypic level. However, it had non significant correlation with fibre fineness at both the levels.
