Abstract
The article investigates the formation of morphobiological traits in cotton families and breeding lines developed through complex intervarietal hybridization under the 0:1:0 irrigation regime simulating artificial water-deficit conditions. Biometric and statistical analyses were conducted for plant height and the height of the first fruiting branch. The results demonstrated that the breeding lines T-14 16/14, T-85-87/16, and T-21-23/16 exhibited high phenotypic stability and significant breeding value, making them promising genetic resources for developing new drought-tolerant cotton cultivars.
