Distinct G.herbaceum (desi cotton)tracts developed in Gujarat and Karnataka due to harsh cotton growing conditions. Kalyan tract (0.57 m ha.), Dhumad tract (0.06 m ha.) and Digvijay tract in central Gujarat (0.15 m ha.) are the predominant areas in Gujarat state. About 90 percent of desi cotton is covered by just four varieties i.e. V 797, G Cot 13, G Cot 21, and G cot 23. Denim culture requires, coarse, strong and clean stretchable fibres that can be fulfilled by these cotton varieties of G. herbaceum. However, G. herbaceum is wreaked with quality attributes like trash content. At the same time these are the cottons that would be used for advanced modern technology like rotor spinning where cleanness is essential factor.
These cottons can be cleaned up below 8 per cent trash content by combination of both traditional and modern technology of ginning process. This type of raw cotton will be made available on demand
