Gossypium arboreum species of cotton is most widely distributed in the country. It has stress tolerance & grown on varied type of soils. The requirement of arboreum species for plant protection is less compared to hirsutum species. The structure of leaves of arboreum species are genetically modified to develop moisture and pest tolerance compared to hirsutum. The cost of seed of hirsutum hybrids & pesticides are higher which make heavy burdon on cultivators. The hirsutum hybrids are more susceptible to moisture stress. Under such situation arboreum species are known for stress tolerance. But their yield potential are comparatively low. The present arboreum species are mostly indeterminate in habit, their plant phenology make it difficult for management including cotton picking. The hybrids have higher yield potential & may produce different phenology which permit better management including cotton picking. Recently some private companies have developed arboreum hybrids but its phenological requirement & nutrient particularly nitrogen is the present need to increase productivity and sustainability of cotton. The details regrading this are given in detail in this book.
