摘要
综述了两系法杂交小麦育种研究的现状,针对限制两系杂交小麦大面积生产应用的主要因素,从提高杂种优势幅度、保证制种纯度、降低杂交种生产成本、提高杂交F1的恢复度等方面进行探讨与分析,并对两系杂种小麦的发展前景进行了展望。
This paper overviews the research status of two - line hybrid wheat breeding. Aiming at its limiting factors of large - scale applieation, the problem of increase yield, purity of hybrid seed, reduce hybrid production cost and restoring degree of hybrid F1 were analyzed. The development prospect of two - line hybrid wheat were also discussed.
