摘　　要：加强旱稻种质资源的抗旱性评价,发掘抗旱基因资源,加快传统旱稻品种的遗传改良,发展旱稻生产,对于缓解水资源短缺、充分利用土地资源、改善日益恶化的生态环境和保障全球粮食安全具有特殊的意义。本文综述了旱稻的抗旱性和遗传改良的研究现状,并对今后旱稻的研究趋势作了初步探讨。It is of vital significance to enhance the evaluation of drought resistance of upland rice germplasm resources,explore drought-resistance gene resources,accelerate genetic improvement of traditional upland rice varieties and increase upland rice production,so as to relieve water shortage,make maximum use of limited land resources,improve the rapidly deteriorating ecological environment and ensure global food security as well.The current research status on drought resistance and genetic improvement of traditional varieties in upland rice were explored and summarized in this paper.Following this,further efforts were also devoted to a preliminary discussion of the future trends of researches on upland rice.
