Analysis of Genetic Similarity of Dolsan Leaf Mustard Based on Several Horticultural Traits and RAPD

摘要

The characteristics of 24 leaf mustard (Brassia junced) accessions were analyzed using quantitative characters and principal component analysis. Cumulative contribution of fresh weight, dry weight, leaf length and number of leaf showed high volume bythe principal component analysis. The genetic relationship among 24 accessions can be analized by these four characters. In addition the 'Goheung dongil' was selected for greatest accessions in only yield side. RAPD marker was used to analysis the DNA polymorphism and genectic relationship among 24 accessions. Four random primers were selected by which 12 polymorphic bands. Based on the UPGMA cluster analysis 24 accessions were separated into five groups. However, the results that showed very close relationship in quantitative character analysis were not constantly agreed with RAPD analysis. The results of quantitative analysis and application of the 12 RAPD markers are available for the Fl hybrid production by using cytoplasmic male sterility of leafmustard.
