摘　　要：水稻重穗型恢复系宜恢1577是用云南地方偏粳型紫稻与抗病恢复株系R16杂交选育而成,具有株型好、恢复力强、配合力高、穗大粒多、开花习性好、花粉量足、制种产量高等特点。用宜恢1577组配的冈优1577、Ⅱ优1577、宜香优1577和N优1577等高产、优质型杂交水稻组合,已通过四川省审定,其中冈优1577、宜香优1577还通过了国家审定。The rice restorer line Yihui 1577 was developed from the cross between a local japonica purple rice variety in Yurman 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 F1 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）, Ⅱ You 1577 （ Ⅱ - 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 Comnfittee. Furthermore, Gangyou 1577 and Yixiangyou 1577 were certified and released by the National Crop Variety Release Committee.
