Phenotypes of three genotypes under well-watered and drought stress conditions. (A) Well-watered and 3 days drought stressed phenotypes of P28, HHZ, and H471 at the tillering stage. (B) Grain yield performance of HHZ, P28, and H471 under drought stressed and well-watered conditions. Each column represents mean ± s.d. (nine replicates); **p <0.01 versus HHZ (ANOVA, Dunnett’s multiple comparison test).
