Assessment of ploidy behaviour in doubled diploid wild species of Gossypium

Abstract

Gossypium L. is an important genus and it includes 46 wild species. Use of wild species in crop improvement programme at a stage is inevitable where the use of available cultivar variability is found ineffective for further improvement in productivity, quality or sUNival against pest and diseases. In such situation, the plant breeder has to resort to wider crosses such as interspecific or intergeneric ones for expanding the gene pool and its further utilization in crop improvement programme.
