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.
