The research work comprising of genetic variability, heritability and genetic advance as well as correlation and path analysis study for 12 quantitative traits in three genotypes of cotton (Gossypium arboreum L.) was carried out during 2015 and 2016 at Research Farm of Cotton Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar, India. The genotypic differences were significant for all the traits except number of monopods/plant and number of seeds/boll. The variability studies indicated that high PCV and GCV were observed for seed cotton yield per plant, lint yield per plant and number of bolls per plant. Seed cotton yield per plant, lint yield per plant, number of bolls per plant and days to first flower shows high heritability with high genetic advance over mean. The correlation study revealed that seed cotton yield was found to be positively and significantly correlated with traits viz. lint yield per plant, number of bolls per plant, boll weight, seed index, number of seeds per boll, number of monopods per plant, plant height, days to boll bursting and days to first flower. Path analysis revealed that lint yield per plant exhibited maximum positive direct effect on seed cotton yield followed by number of bolls per plant, seed index, boll weight and plant height. Hence selection for these traits would be quite effective to improve the seed cotton yield.
