Breeding of restorer line JXR-33 and the hybrid rice Jinliangyou33 with high yield

The study aimed at improving the disadvantage character of restorer line 946 which is R-line of the Jinliangyou 33,the results showed that JXR-33 had been improved distinctly in major traits,such as growth period,plant height,panicles,the grain weight etc.,as well as grain quality.Undering retaining high-yield of Jinliangyou 36,the F1 hybrids such as Hs-3/JXR-33 (Jingliangyou33) showed good grain quality in appearance and high-yield in producing the hybrid seed,and showed a good prospect for commercial production.
