中百优华占是中国水稻研究所用中100A与华占组配育成的高产、优质、早熟杂交晚稻，2014年3月通过江西省品种审定。为更好地发挥中百优华占的高产制种潜力，笔者于2014-2015年夏季在浙江富阳开展了中百优华占高产制种技术的研究。本文主要介绍了中百优华占父母本的特征特性，提出了中百优华占高产制种的关键技术措施。

Zhongbaiyouhuazhan is a new indica hybrid rice combination, derived from the cross of Zhong 100A/Huazhan, developed by the China National Rice Research Institute. It has high and stable yield, fine quality, short growth period, and was approved to commercial production in Jiangxi Province in March, 2014. For the sake of playing the potential of F1 seed production of Zhongbaiyouhuazhan, the author studied the high-yielding seed production techniques. The main characteristics of parents of Zhongbaiyouhuazhan were introduced in this paper, and the key points of F1 seed production techniques were also given.
