论小麦高产育种与杂种优势的利用

Discussion about the High-yield Wheat Breeding and the Utilization of Hybrid Vigor

山西作为我国的农业大省,在多年来通过对小麦杂种的研究取得了突破性进展,很多品种已经推广应用。但从宏观层面上看,目前杂种小麦种植面积依然很小,这就需要对杂种小麦技术进一步展开研究。着重探究高产小麦品种的特征,对常规育种手段进行分析,继而提出杂种优势的利用。

China isa great agricultural country. Corn, rice and wheat are collectively called ＂the three pillars of China＇sagriculture＂, thus it can be seen that the wheat farming industry is very important in such country. In Shanxi, a major agricultural provincein China, it has madea breakthrough in the study on wheat hybrids over the years, and many varieties have been popularized and applied.However, at the macro level, it can be seen that the hybrid wheat planting area is still very small at present, thus it requires further toresearch on the hybrid wheat breading technology. Based on that, this paper focused on exploring the characteristics of high-yield wheatvarieties and analyzing the conventional breeding methods, and then proposed the utilization of hybrid vigor.
