Heterotic study for seed cotton yield and fibre quality parameters in Gossypium hirsutum L.

Cotton is an important commercial crop which provides raw material in the form of lint to the textile industry. It is grown in tropical and sub-tropical regions of more than 110 countries the over world. In India, nearly 70 per cent of the area is occupied with commercially hybrids. Cotton had tremendous potential for improvement of quantitative and qualitative characters by better commercial exploitation of hybrid vigour (Chinnadurai and Rangaswamy, 1974). Therefore, present investigation was undertaken to find out the extent of heterosis for seed cotton yield and fibre quality traits in upland cotton (G. hirsutum L.).
