Identification of natural colour genotypes with stable colour and excellent fiber qualities for machine spinning is important in manufacturing ecological and organic textiles. Assessment of the extent and distribution of genetic variation in a crop species is essential in establishing the pattern of diversity and evolutionary relationships. We evaluated 240 colour-cotton genotypes of varying shades of brown and green lint with five white genotypes as checks during kharif 2016 in Agricultural Research Station, Dharwad Farm, University of Agricultural Sciences, Dharwad using an augmented design. Analysis of variance indicated that there was significant variation in the experimental material. Ample variability was observed in the experimental material studied for all the characters. The genotypes MB-535-1 (medium brown), DB-9-1 and DB-57-2 (both dark brown), C-318-1 (cream) and G-4-1 (green) were identified as promising high yielding genotypes compared to the white check varieties, Sahana and ARBH-813. However, the white check varieties were better in fiber quality traits. Among the coloured genotypes, cream coloured genotypes were superior in yielding ability. The quality traits were much more superior in white cotton followed by in green and then in, brown cottons.
