优质、高产、早熟杂交晚稻中百优华占高产制种技术

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。

High-yielding Seed Production Techniques of Hybrid Combination Zhongbaiyouhuazhan with Fine Quality,High Yield and Short-duration

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 com-mercial production in Jiangxi Province in March, 2014. For the sake of playing the potential of F 1 seed production of Zhongbaiy-ouhuazhan, the author studied the high-yielding seed production techniques. The main characteristics of parents of Zhongbaiy-ouhuazhan were introduced in this paper, and the key points of F1 seed production techniques were also given.
