丁氏稻种资源有利基因挖掘与创新研究进展

    Research progress in favorable gene mining and innovation of Ting’s rice germplasm

    • 摘要: 稻种资源是水稻生物育种的重要物质基础。我国保存的稻种资源数量超过9万份,丁氏稻种资源(Ting’s rice germplasm)是极具特色的一类,主要包括丁颖在20世纪20—30年代广泛收集的7 000多份各地的栽培稻、卢永根在20世纪90年代组织收集的2 000份野生稻资源以及所创制的新型四倍体水稻新种质等。本文总结了近20多年来丁氏稻种资源的研究进展,并提出了今后研究应重点解决的问题,为水稻育种更好地利用该资源提供参考。

       

      Abstract: Rice germplasm provides an important fundation for biological breeding. The total number of rice germplasm preserved in China exceeds 90000, among which Ding’s rice germplasm is a unique category. The Ding’s rice germplasm mainly included over 7000 cultivated rice varieties collected by DING Ying in various regions from 1920s to 1930s, 2 000 wild rice lines collected by LU Yonggen in the 1990s, the newly-devolped neo-tetraploid rice germplasm, and so on. This article summarized the research progress of Ding’s rice germplasm in the past 20 years and proposed the key subjects in future research, with the aim of providing a reference for better utilization of this germplasm in rice breeding.
