两个位点对222个子代进行了评估。,Agricultural Research Station, Annigeri and Main Agricultural Research Station, Dharwad to estimate genetic variability and to identify superior progenies for seed cotton yield, yield contributing and fibre quality traits. The analysis of variance revealed presence of sufficient variability in the material for seven traits at both locations. High phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were recorded for number of bolls per plant and seed cotton yield per plant,  while, moderate variability estimate was recorded for plant height and low PCV and GCV were noticed for boll weight, ginning out turn, seed index and lint index traits at both the locations. High heritability was observed for seed index exhibited 97 per cent with moderate genetic advance as percent mean (GAM) at both the locations. High GAM was observed for number of bolls per plant, seed cotton yield and plant height. Moderate GAM was noticed for boll weight and seed index traits at both locations. An attempt was made to identify superior progenies, maximum number of superior progenies were observed for seed cotton yield at Dharwad (33 progenies) followed by Annigeri (24 progenies).
