‘Chuanyou 2189’ was developed by crossing the 3-line male sterile‘Chuanxiang 29A’ and the restorer line‘Fuhui 2189’ . ‘Fuhui 2189’ was a result of crossing ‘Shuhui 527’ as the female parent with R2 in Hainan in the spring of 2003. Its progeny were planted in the rice-blast-infected field at Shanghang for cultivar-screening .The selected plant lines were repeatedly cultivated for several generations in Shaxian and Hainan to assure cultivar stability .The finally obtained ‘Chuanyou 2189’ exhibited the desirable characteristics of large panicle ,numerous grains per panicle ,color change during mycelium ripening ,high yield and high seed production .As a result ,it has been certified by Fujian Crop Variety Evaluation Committees in 2011. This paper presents the breeding procedures , hybrid characteristics ,cultivation and seed production of ‘Chuanyou 2189’ .
