Cluster analysis in the breeding of leguminous crops

Abstract

According to the results of cluster analysis, the studied 423 genotypes (56 combinations) of F2 soybean, 122 genotypes (17 combinations) of F2 faba beans and 27 genotypes (4 combinations) of F2 beans developed by the method of hybridization have been divided into five clusters according to the main valuable farming traits. It has been established that the division of F2 soybean plants into 5 clusters (K5) is of the greatest interest. According it, 12 (2.8 %) plants were selected in the best group K5-IV, which exceeded the corresponding indices of other groups K5 as well as the best grroups by the main valuable farming characteristics and the best groups К2, К3 and К4. When dividing F2 plants of faba beans in 5 clusters (K5), group IV (K5-IV) was the best and included 17 (13.9 %) plants with characteristics that exceeded the average index of all groups of this cluster. The division of plants F2 of faba beans in 5 clusters (K5) made it possible to distinguish the group K5-II, in which the plants with the highest indices are located.
