点式突破玉米育种法是一种综合的优化育种法。该方法将目前应用的杂优群划分为两群即种质资源群与生产优势群,有针对性地对生产优势群进行改良。从确立玉米育种目标选择突破点,然后构建创新核心种质资源,在选育过程中选育方法多样灵活,采用“一对一”法测定配合力,多点试验统计分析,结果准确可靠,构建适度规模的循环育种体系。
Breakthrough corn breeding method is a comprehensive optimization of breeding methods. The method divides the currently used heterozygotes into two groups, that is, the germplasm resource group and the production advantage group, and improves the production advantage group in a targeted manner. From the point of establishing the breeding target of maize breeding to select the breakthrough point, and then construct the innovative core germplasm resources, the selection and breeding methods are diversified and flexible during the breeding process, the combining ability is determined by the “one to one” method and the statistical analysis of the multi-point test is accurate and reliable , Build a moderate scale cycle breeding system.
