援西非农业项目玉米育种的策略建议与探讨

Suggestion and Discussion of Maize Breeding in West Africa Assistance Agricultural Project

通过剖析西非地区玉米品种情况及其面临的问题,提出援西非农业项目玉米育种的策略建议:根据不同国家情况确定育种目标,培育不同类型玉米杂交品种,并注重品种耐旱、耐贫瘠等优良性状的选择;按"地方系"与"外来系"的配对模式组配,提高育种效率,并兼顾自交系一般配合力和产量选择;开展示范与配套技术研究以利于新品种推广等。同时对今后的工作思路进行探讨,加强西非地方种质与引进外来种质的研究利用,针对当地生产条件及收获习惯选育品种,以相对简单科学的试验设计获取完整、正确的试验结果,稳定援外项目育种队伍及为育种成果联合开发寻求出路等。

By understanding the situation of maize varieties and the problems faced in West Africa, this paper puts forward some strategies for maize breeding in West Africa. The breeding objectives are determined according to different countries, and different types of hybrids are cultivated, and the varieties are drought-tolerant and barrenresistant. The selection of excellent traits;according to the matching mode of "local department" and "exotic system", improve breeding efficiency, and pay attention to the general combining ability and yield selection of inbred lines;carry out demonstration and supporting technology research to promote new variety. At the same time, the future work ideas are discussed, strengthening the research and utilization of local germplasm and introduction of exotic germplasm in West Africa, the breeding of variety should adapt to local production conditions and harvesting habits, and obtain complete and correct test results with relatively simple and scientific experimental design. Stabilize the foreign aid project breeding team and seek a way out for the joint development of breeding results.
