摘　　要：成恢177系四川省农科院作物研究所用籼型恢复系绵恢502与美国光身稻Lemont杂交,后代通过花药培养和病圃稻瘟病抗性鉴定选育而成的优质、抗稻瘟病、高配合力、强恢复力水稻恢复系。成恢177已配组出川香优2号、冈优177、中优177和D优177等4个组合通过国家或省级品种审定,也作为稻瘟病抗性资源在杂交水稻育种中应用。Chenghui 177, derived from the F6 progeny of an indica restorer line Mianhui 502 crossing with an American glabrous rice variety Lemont by way of anther culture and identification of rice blast in nurseries, is a rice restorer line with good grain quality, strong blast resistance, high combining ability and strong restoring ability. Four hybrids derived from Chenghui 177, including Chuanxiangyou 2 （Chuanxiang 29A/Chenghui 177）, Gangyou 177 （Gang 46A/Chenghui 177）, Zhongyou 177 （Zhong 9A/Chenghui 177） and D You 177 （D62A/Chenghui 177） have been examined and approved for release by the national or provincial crop variety appraisal committees. Furthermore, Chenghui 177 has also been used as a blast resistant donor in hybrid rice breeding.
