摘要
简述了我国旱稻研究现状。指出旱稻种质在与高产有关的性状上具有极大的选择空间;通过远缘杂交导入外缘高抗优良基因,加强对旱稻现有种质资源的保护,培育节水抗旱、优质高产的旱稻新品种,是我国稻作发展的主要方向。
The paper briefly stated the present research situation of upland rice in China. The researches were mostly focused on drought-resistance identification and genetic improvement of upland rice. There is great selection space in upland rice germplasm related to the high yield characters. It is the main direction of upland rice in China to transfer useful alien genes by distant hybridization,and to develope the new varieties of water saving, drought resistance, high yield and good quality.
