RAPD를 이용한 고추냉이의 유연관계 분석

초록

The genetic variation and intraspecific relationships between 10 individuals of seven cultivars and one Ulleungdo native of Wasabia japonica were investigated using PARD (Randomly Amplified Polymorphic DNA) analysis. The 21 primers out of 50 random primers were amplified for all tested plants. The 68(47.2%) among 144 bands derived from 21 primers showed polymorphism, and 3.2 bands per primer were observed. Number of bands per primer was ranged from 2 to 13, and average numbers were 6.8. The phenograms for 11 analyzed individuals by RAPD markers were not matched well with those of the result by morphological characters since they were clustered monophyletic at the similarity coefficient value ranged from 0.81 to 0.96. The Ulleungdo native individual was clustered sister to Daruma, Simanesairai, Sawa, and Hujidaruma cultivars. The RAPD markers were not useful to evaluate the intraspecific variations in Wasabia japonica cultivars, therefore need to more specific molecular phylogenetic characters such as AFLP thchnology and gene sequence of nuclear and chloroplast DNA.
