Breeding of Bread Wheat With Drought Adaptive Root Traits
Food and Energy Security, Volume 14, Issue 6, November/December 2025.ABSTRACT Global wheat production is extending to dryland and tropical environments prone to drought and heat stress due to breeding and deploying new‐generation ideotypes with desirable product profiles. However, yield gains are low and stagnant under these environments, attributable to abiotic stresses, primarily drought.
