The Principle and Method of Single-plant Similarity-difference Selection and Its Application in Wheat Breeding

摘要

In order to overcome the limitation of traditional breeding by means of experiences, a new method of single-plant selection was proposed by using the principle of similarity-difference analysis, which was considered as the method of single-plant similarity-difference selection. Its principle and steps were introduced. By means of the breeding data of Yumai 35, Anmai No.l and Anmai No.7, the analysis of single-plant similarity-difference selection was made in the process of single-plant selection. The results show that the method is feasible and efficient in the practice of breeding. Based on this, the superiorities of the method were discussed. It is pointed that combining the method with the technique of molecule marker assisted selection will is a very meaning study direction.
