YIELD AND PHENOTYPIC TRAITS OF SEMIDWARF AND NORMAL-STATURED BARLEY (HORDEUM VULGARE L.) GENOTYPES GROWN UNDER DIFFERING LEVELS OF MOISTURE STRESS

Abstract

Semidwarf and normal-statured barley genotypes were grown in several environments differing mainly in the levels of plant-available soil moisture. Grain yields (12% moisture) differed significantly due to environment and genotype and there was a nonsignificant tendency for semidwarf genotypes to yield less, relative to their tall counterparts, when grown in environments with restricted moisture supply. The stature of the genotype did not appear to influence the expression of yield components, harvest index or flag leaf area.
