Studies on the performance characteristics of collected native sprout soybeans in Korea Ⅱ. Varietal classification by multivariate analysis

The purpose of this experiment was to classify the varietal groups and to select parents for breeding in sprout soybean. One hundred and thirty three varieties were classified based on 13 chracters measured by Euclidian distance D² and complete linkage cluster analysis was attempted. Ten varietal groups were classified by the complete linkage cluster analysis based on the D² computed in 13 chracters. Group Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ, Ⅶ, Ⅷ, Ⅸ and Ⅹ contained 26 varieties(7%), 9(7%), 6(5%), 4(3%), 9(7%), 22(17%), 2(1%), 39(29%), and 7(5%), respectively. Maturity type of group Ⅷ and Ⅹ, Ⅱ, Ⅲ and Ⅴ, the other groups were classified early, late and medium, respectively, by the day from seeding to flowering. Some varietal groups were associated with their geographical origin. The number of mainstem nodes and chlorophyll content were main contributors to the D² in both intra and inter groups, and the degree of those was not significant.
