一、前言我省是我国春小麦主要产区及重要商品粮生产基地之一。小麦总产量一般占粮豆薯总产量的五分之一左右,所以小麦产量的高低,在粮食生产中起着举足轻重的作用。于是,选育早熟高产小麦新品种就成了七十年代初期的重要育种目标之一。正值此时,墨西哥的“绿色革命”席卷世界,当时我们也引 I. Introduction The province is one of the major spring wheat producing areas and an important commodity grain production base in China. The total output of wheat generally accounts for about one-fifth of the total output of the bean, so the level of wheat production plays an important role in food production. As a result, breeding new varieties of early maturity and high yield of wheat became one of the major breeding goals in the early 1970s. At this time, Mexico’s “green revolution” swept the world, at that time we also cited
