| Abstract: | The rice restorer line Yihui 1577 was developed from the cross between a local japonica purple rice variety in Yunnan and R16, a restorer line with good disease resistance. It is characteristic of good plant type, strong restoring ability, high combining ability, large panicle, good flowering habits, heavy pollen load and high yield of F_1 hybrid seeds. Crossing it with different types of CMS lines, a group of hybrid rice combinations with high yield and good quality have been developed. Among them, Gangyou 1577 (Gang 46A/Yihui 1577), You 1577 (-32A/Yihui 1577), Yixiangyou 1577 (Yixiang 1A/Yihui 1577) and N You 1577 (Nj7A/Yihui 1577) were certified and released by the Sichuan Crop Variety Release Committee. Furthermore, Gangyou 1577 and Yixiangyou 1577 were certified and released by the National Crop Variety Release Committee. |
