Cotton genetics is the branch of genetics that focuses on the study of the genetic basis of traits and characteristics in cotton plants. This research area seeks to understand the genetic mechanisms that control important traits in cotton, such as fiber quality, yield, disease resistance, and environmental adaptation. By analyzing the genetic diversity within different cotton varieties, researchers can identify genes associated with desirable traits and use this knowledge to develop improved cotton varieties through breeding and genetic engineering techniques. This research is essential for enhancing the productivity and sustainability of cotton production, which is a vital industry worldwide.
