Jinliangyou 4,a new two-line early hybrid rice combination with both high yield and good grain quality,was developed by crossing Jinshan S-2 (a PTGMS line with low critical temperature and good grain quality) with the restorer line Zao R-10. It yielded an average of 7.25 t/hm2 in two years (2004 2005) of the regional yield trials for early rice of Fujian Province,5.71% higher (significant at 1% level) than that of the check Weiyou 77. Consequently,it was registered and released for commercial production in Fujian Province in 2007.
