摘　　要：为提升中国谷子杂优利用研究水平,本研究通过剖析中国谷子杂优利用研究的发展历程,总结其研究进展,探讨谷子杂优利用中的问题。将中国谷子杂优利用研究归纳为4个阶段:起步、发展、应用、提升。并从8个方面分析了存在的问题:育性遗传与恢复、高异交结实率亲本创制、抗除草剂、杂种优势不强原因及优势群划分、胞质类型单一和胞质专化性病害侵染机制、杂优机理及预测、品质评价、小米深加工。提出了谷子杂优利用的7个发展趋向:高产是永恒的主题、商品品质食味品质兼优、产业特点更趋突出、基础研究与应用研究须紧密结合、杂交种组合配制主动化、杂交种应用趋向、制种产业化。To improve the research level of foxtail millet heterosis utilization,this study reviewed the development history of the research on the utilization of foxtail millet heterosis in China,summarized its research process,and discussed the problems in the utilization of foxtail millet heterosis.The research on the utilization of foxtail millet heterosis in China was divided into four stages as initial stage,development stage,application stage and promotion stage.The existing problems in the utilization of foxtail millet heterosis were analyzed from eight aspects:inheritance and restoration of fertility,creation of parents with high outcrossing rate,herbicide resistance,reasons of weak heterosis and classification of heterotic groups,single cytoplasmic type and infection mechanism of cytoplasm-specific diseases,mechanism and prediction of heterosis,quality evaluation and deep processing of millet.Seven development trends of the utilization of foxtail millet heterosis were proposed,including taking high yield as the research focus,breeding varieties with excellent commercial quality and taste,building outstanding characteristics of millet industry,closely integrating basic and applied research,initiatively creating hybrid combination,updating application trend of hybrids and promoting the industrialization of seed production.
