Abstract

The molecular relationships have analyzed between the Bombyx mandarina(wild silkworm) and Bombyx mori strains (domesticated silkworm, geographical silkworms). A total of 166 polymorphic RAPD markers amplified from 35 different primers were used to analyze the molecular relationships among thirteen silkworm strains. The genetic similarity coefficient between Bombyx mandarina and Jam305 showed the lowest genetic similarity value with 0.451, Bombyx mandarina and Bibaekjam showed the highest genetic similarity value with 0.958. These strains were classified into Bombyx mandarina(a wild silkworm) and Bombyx mori(twelve domesticated silkworm) groups upon the genetic similary coefficient of 0.55. Further classificient of 0.60; the 1st sub-group (J111, Bibaekjam, $pnd^{ps}$), the 2nd sub-group (Galwon, C18, od yujam, JAM306, C108), the 3rd sub-group(R-hwang, p50), the 4th sub-group(zebra) and the 5th sub-group(JAM305). According to this study, RAPD markers seems to be a valuable tool for molecular relationships and classification among the silkworms.

본 연구는 RAPD마커를 이용, 멧누에와 집누에의 분자적 유연관계를 분석하였다. 공시한 35개의 primer에서 166개의 RAPD마커를 얻었으며, 이들 마커를 UPGMA에 의해 분석한 결과, 멧누에와 분자적 유사계수가 가장 낮은 품종은 잠305였고, 가장 높은 품종은 Bibaekjam이었다. 또한, 분자적 유사계수 0.55에서 멧누에와 집누에 계통군으로 분류되고, 0.60에서 3개의 아군 그룹과 2개의 독립개체로 분류되었다. 제1아군에는 J111(일본종계),$pnd^{ps}$(일본종계), Bibaekjam(일본종계)이, 제2아군에는 Galwon(중국종계), C18(중국종계), od yujam JAM306(중국종계), C108(중국종계)이, 제3아군에는 R-hwang(중국종계)이 포함되어 있었고, zebra(유럽종계)와 JAM305(일본종게)는 독립개체로 분류되었다.
