Methods for producing cotton plants with enhanced drought tolerance and compositions thereof

摘要

The present disclosure is in the field of plant breeding. The disclosure provides methods for breeding cotton plants having a staygreen trait using marker-assisted selection. The disclosure further provides germplasm that stays green under high drought stress and provide yield advantage over non-staygreen germplasm. The disclosure also provides genetic markers associated with staygreen QTLs for introgressing these QTLs into elite germplasm in a breeding program and producing novel cotton germplasm that performs better under water-limited conditions.
