| Abstract: | Zhuliangyou 120,developed by the Yahua Seeds Institute of Hunan, is a new two-line early hybrid rice combination derived from the cross of Zhu IS, a PTGMS line with low critical sterility-inducing temperature and wide compatibility, and a new restorer line Hua 120. In the Southern China Rice Regional Trials in 2003 and 2004, this combination was characterized with high and stable yielding ability, suitable growth duration, strong blast resistance, comparatively good grain quality, and wide adaptability, indicating it has a good applied prospect. It was registered and released to commercial production nationwide in China in June, 2005. The breeding procedure, major characteristics and cultivation and seed production techniques of Zhuliangyou 120 were introduced in this paper. |
