摘　　要：干旱胁迫是作物生产的主要非生物逆境之一,严重阻碍了作物的生产和可持续发展。青藏高原气候非常恶劣,西藏青稞种植区约有3/4为旱地,该地区年降水分配不均,干旱胁迫严重影响高原青稞正常的生长发育。开展青稞抗旱育种研究,可以有效地确保稳产目标的实现,为粮食安全和农牧民生活水平的逐步提高提供保证。近年来,关于干旱胁迫的分子调节及青稞抗旱相关的研究取得了长足的进展。本文结合植物抗旱胁迫响应和青稞抗旱研究,综述了青稞耐旱性遗传学和基因组学的最新进展,并将其作为重新审视青稞耐旱性分析方法的基础。Drought stress is one of the major abiotic stresses in crop production, which seriously hinders crop production and sustainable development.The climate in the Qinghai - Tibet Plateau is very bad.About three-quarters of Tibetan highland barley planting areas are dry lands.The annual rainfall distribution in this area is uneven.Drought stress seriously affects the normal growth and development of highland barley.The research on drought-resistant breeding of highland barley can effectively ensure the realization of the goal of stable production and provide guarantee for food security and the gradual improvement of the living standards of farmers and herdsmen.In recent years, the research on molecular regulation of drought stress and drought resistance of highland barley has made great progress.In this paper, the latest advances in genetics and genomics of drought tolerance of highland barley are reviewed in the light of the response of plants to drought stress and drought resistance of highland barley, which will serve as a basis for re-examining drought tolerance analysis methods of highland barley.
