江原地方 在來鍾 콩의 蛋白質 및 脂肪 含量과 RAPD

Protein and lipid contents of Kangwon local soybeans and their RAPDs

Protein and lipid contents as well as the genetic diversity among local soybean varieties collected from all over the Kangwon province were investigated to provide the basic information for improving soybean cultivars. The protein content was varied from 33.2% to 48.8% with average of 38.7% in the dry weight of the seed. Lipid content was also varied from 14.2% to 22.2% and the average was 17% of the dry weight of the seed. There were negative correlations between the high contents of protein and lipid and the high yield. Although major differences were not found in the seed storage protein profile in PAGE analysis, polymorphisms were found at the DNA level in the RAPD analysis for investigating genetic diversity. There were three gorups at 15% of diversity level and ninety percent of the landraces were able to be clustered at 20% of diversity level by the RAPD analysis. There were three landrace lines clustered beyond 40% of diversity level, which could be valuable genetic resources in soybean improvement program.
