Utilization of wild species for cotton improvement

Abstract

The population based on complex crosses involving five diploid and two tetraploid species of Gossypium, was utilized following conventional breeding. The autotetraploids of diploid wild species and G. barbadense were crossed with G. hirsutum. The crosses were carried in bulk up to F4 in isolated field and practiced onward selection for useful traits converged in the population thereafter for more than ten generations.
