水稻品种资源的耐盐性是其抗逆特性表现之一,它已为广大水稻育种工作者所重视。国际水稻所,为挖掘耐盐种质资源,在世界有关国家建立了国际鉴定圃。以便尽快获得耐盐种质资源,作为育种亲本。我国稻区辽阔,且分布在沿海及内陆盐碱地上较多。这些稻区长期来,均依靠引灌淡水洗盐,改变生态环境以适应水稻的生理特性。近年来,由于生态环境(主要是水资源)的急剧变化,严重地威胁着这些稻区水稻栽培面积和产量的稳定与发展。据此,中国农科院品种资源所,自1980年起,亦将水稻品种资源耐盐性鉴定列为研究项目之一。
Salt tolerance of rice varieties is one of the characteristics of its resistance to stress, which has been valued by the majority of rice breeding workers. International Rice Research Institute has set up an international appraisal nursery for the purpose of mining salt-tolerant germplasm resources in the countries of the world. In order to obtain salt tolerant germplasm resources as soon as possible, as breeding parents. China has a vast area of rice and is distributed in coastal and inland saline-alkali soils. These paddy areas have long relied on irrigating fresh water for salt washing and changing the ecological environment to adapt to the physiological characteristics of rice. In recent years, due to the drastic changes in the ecological environment (mainly water resources), it has seriously threatened the stability and development of rice cultivation area and output in these paddy areas. Accordingly, the Chinese Academy of Agricultural Sciences Institute of Resources and Resources, since 1980, rice varieties will also be salt tolerance identification as one of the research projects.
