盐碱是作物生产的大害,全球范围内仅热带、亚热带受盐害影响的稻田面积就达1 500万hm2,我国约有2 700万hm2盐碱地,其中滨海地带的盐土面积约为516.7万hm2。本文从经典遗传及分子水平研究了水稻品种耐盐性的遗传,以及育种策略,为耐盐水稻品种的选育提供理论基础。 Salt and alkali are the major crop damage. In the world, the area of ​​paddy fields in the tropics and subtropics affected by salt damage has reached 15 million hm2. There are about 27 million hm2 of saline-alkali land in China, of which the saline-alkali area in the coastal zone is about 5.167 million hm2 . In this paper, the inheritance of salt tolerance of rice cultivars and their breeding strategies were studied from the perspective of classical heredity and molecular level, which provided a theoretical basis for the breeding of salt-tolerant rice varieties.
