摘 要:木薯在我国作为生物质能源、工业淀粉原料和潜在的粮食资源是热区最重要的经济作物之一。由于木薯遗传高度杂合和有性子代严重分离等不利因素导致育种周期长,育种进展缓慢。针对木薯育种面临的挑战,现提出综合育种的对策,并详细阐述木薯综合育种所需条件和流程以及发展前景,为缩短木薯育种年限和提高育种效率提供新思路。

Abstract: In China, cassava (Manihot esculenta Crantz) mainly provides the raw materials to produce industrial starch and biofuel and is used as a potential food crop. It is also one of the most important cash crops in tropical areas. The breeding progress of cassava is slow because of its heterozygous genetic makeup and sexual progenies with severe separation, which makes it time consuming to breed efficiently. Based on these challenges, we developed the strategy of an integrated breeding for cassava genetic improvement. The necessary conditions, workflow and prospects for cassava integrated breeding were elaborated in the present study.
