摘要
Ⅱ优838是四川省原子能应用技术研究所用Ⅱ-32A为母本与辐恢838配组而成的杂交中籼组合,1995年5月通过四川省农作物品种审定委员会审定,1999年通过国家农作物品种审定。具有茎秆粗壮,耐肥抗倒,产量高,稳产性好,适应性广等特点,在南方籼稻区已大面积推广种植。根据多年对亲本的观察和制种实践,总结了该品种的高产制种技术。
A mid-season indica hybrid rice combination II You 838 was developed from the cross of a CMS line II-32A and a restorer line Fuhui 838 by Sichuan Institute of Atomic Energy Application Technology,and was released by Sichuan province in May 1995 and by the state in 1999.It was characterized by sturdy stem,tolerant fertilizer and resistant lodging,high and stable yield,wide adaptability,etc.This combination was grown by farmers at southern indica rice areas on large-scale.According to parental observation and practice of hybrid rice seed production in several years,the high-yielding seed production techniques for this combination were summarized.
