| Abstract: | The preliminary observing results on the growth characteristics of parents in three-line hybrid rice Huayou 54 showed that differences of growth duration and leafing rate were small, synchronization of panicle flowering and daily anthesis was good between CMS line Huanong A and restorer line T54, and the vitality of stigma in Huanong A was strong. These characteristics are favourable to increase yield in its hybrid rice seed production. |
