Drought stress reshapes the genetic architecture of fiber quality and developmental traits in Egyptian cotton (Gossypium barbadense L.): a line × tester analysis under contrasting irrigation regimes.

Abstract excerpt

Water scarcity is an increasing threat to Egyptian cotton production, yet the mechanisms by which drought stress modifies the genetic control of fiber development and plant architecture remain poorly characterized. This study investigated how water deficit alters the genetic architecture of eight fiber quality and agronomic traits in Egyptian cotton, using a line × tester mating design comprising seven lines...
