As a major abiotic stress, drought causes instability and deterioration of malt barley quality. There is distinct difference among barley cultivars in the responses of the main malt quality traits to drought stress. In the previous study, we identified some Tibetan wild barley accessions with relatively less change of malt quality traits under drought. In this study, we examined the impact of drought stress during grain filling stage on grain weight and several important malt quality traits, inc...
