据1986年统计,我国小麦亩产已从建国初期的50公斤增加到203公斤,并出现一些稳产400公斤的地块,小麦总产居世界首位。但这些年来大部分高产麦田一直徘徊在这个产量水平上,未出现更大的飞跃。究其原因,除了育种方法和育种理论研究没有突破性的进展外,更重要的是育种基础材料贫乏。 国内外种质资源虽多,但又具不同的缺点,用起来不很得心应手,仅有少量优良亲本供各家利用,严重影响育种水平的提高。我们分析1983～1987年参加北方冬麦区高肥区域试验的79个品种, According to the statistics of 1986, the output of wheat in our country has increased from 50 kilograms to 203 kilograms in the early days of the founding of the PRC, and some plots with a stable yield of 400 kilograms have emerged. The total output of wheat ranks first in the world. However, most of the high-yielding wheat fields have been hovering at this level of production over the years, with no major leap forward. The reason, in addition to breeding methods and breeding theory of no breakthrough, but more important is the lack of basic breeding materials. Although many domestic and foreign germplasm resources, but with different shortcomings, it is not very handy to use, only a small amount of good parents for each use, seriously affecting the breeding level. We analyzed from 1983 to 1987 to participate in high-fat winter wheat area trial of 79 varieties,
