为了提高新品种亲本自交系种子的繁殖系数,扩大制种面积,加快良种推广速度,降低成本,提高经济效益,笔者从1976年开始,对稀少的玉米自交系进行就地一年两季繁殖途径的试验,并于1978—1983年利用就地一年两季繁殖法进行了5个不同气候年度大面积自交系繁殖,均获得成功。实践证明,这种方法栽培技术容易掌握,操作简单,不需
In order to improve the propagation coefficient of seed of new inbred inbred lines, enlarge the seed production area, speed up the popularization of improved seed, reduce the cost and increase the economic benefits, the author started from 1976 on the rare inbred lines of corn in two seasons The experiment of breeding route and the successful breeding of large-area inbred lines of five different climates in 1978 and 1983 were carried out by using in-situ two-season propagation method. Practice has proved that this method of cultivation techniques easy to grasp, simple operation, not required
