调查与试验结果表明,江西地方名特水稻品种,栽培历史悠久,具有明显的地方特色,值得加以保护和开发利用。但是,这些品种生育期偏长,多为一季稻,且茎秆偏高,单产低;对生态条件要求严格,引种扩种后米质变劣,难以扩大种植面积。因而总产难以增加,影响了其潜在经济效益的发挥。因此,深入研究其特殊米质与生态条件的关系,为引种扩种提供依据;进行遗传改良以提高单产;对开发利用这些珍贵品种资源有重要意义。
Investigation and test results show that Jiangxi famous local rice varieties have a long history of cultivation and have obvious local characteristics that deserve to be protected and exploited. However, these varieties have a long growing period, mostly one-season rice, with high stems and low yields; strict requirements on ecological conditions, and the quality of rice varieties becoming worse after introduction and expansion, making it difficult to expand the planting area. Therefore, it is difficult to increase the total production, affecting the potential economic benefits. Therefore, in-depth study of its special quality and ecological conditions of the relationship for the introduction of expansion provides the basis for genetic improvement to improve the yield; for the development and utilization of these precious varieties of resources is of great significance.
