摘　　要：R337系用广恢398作母本、矮秀占作父本杂交选育而成的籼型三系恢复系,米质优、配合力好、恢复力强,用它与三系不育系配制的杂交组合一般表现出早熟、杂种优势强等特点。所配组合万象优337已先后于2018和2019年通过江西省和广西区的品种审定,红1优337和瑞象优337等组合正在参加各级区域试验。R337, derived from the hybridization between Guanghui 398(as the female) and Aixiuzhan(as the male), was an indica restorer line for three-line hybrid rice. It has good grain quality, high combining ability and strong restoring ability. The F1 hybrids derived form R337 and CMS lines generally show early maturity and strong heterosis. The F1 hybrid Wanxiangyou 337 was registered and released in Jiangxi in 2018 and Guangxi in 2019, and the F1 hybrids Hongyiyou 337 and Ruixiangyou 337 were also under the testing of regional trials.
