ABSTRACT
The work on develop naturally coloured cotton commenced at Maharashtra Hybrid Seeds Co. Ltd. (Mahyco, Jalna, India) in 1993. The objectives were the identification of coloured linted cotton hybrids with high yield and superior fiber traits. Colour cotton was grown and used by mankind as long ago as 2500 BC. Damaging effects of synthetic dyes on the ecosystem has led to expanded interest in naturally coloured cotton. Environment conscious communities in developed countries, particularly in Europe and USA are now developing cotton textiles free from harmful dyes and pesticide residues (Anon 1995). “Fox” Fibers coloured cotton have caught the attention of scientists and textile processors; hence the new interest in India. In the study, heterosis for yield and fiber characters of 40 intra-hirsutum hybrid combinations, obtained from crossing colour linted strains as male and elite white linted cultivars as female was evaluated found that the selected hybrid combinations had better fiber properties than the coloured cotton parents. The results indicate that of all the combinations evaluated, the hybrid MBCH-9 with a potential yield of 1800-2000 kg seed cotton per hectare, upper half mean length of 27 - 28 mm, Micronaire of 3.9 - 4.2, fiber strength at 1/8 gauge of 24 – 25 gm/tex, uniformity index of 78 – 80 and light shining brown colour appeared most promising. Improvement in agronomic and technological performance in evolution of colour cotton hybrid will be required for commercial cultivation and the textile industries.
