Abstract

|
|
B. mandarina of Korean population apparently differs B. mori in isozyme analysis. Fourteen polymorphism occurred B. mandarina not in B. mori at 6 isozymes, Bph, Bes, Amy-hc, Ies, Ict-D, Ict-E. Korean population has shared with the Korean native strain of B. mori in B genotype of Bes, F of Amy-hc, n of Ict-E, M and S of Ict-H. These 5 genotype were known that detection only Korean native strains of B. mori. Nei’s genetic distance based on the genotype of isozyme and hemolymph protein using 4 populations of B. mandarina varied from 0.0350 to 0.0624. The distances of 0.0350 is between Jinju and Chilgok population and between Jinju and Kosung population has the largest distances, 0.0624. In genus of Bombyx, B. mandarina and B. mori, genetic distance varied from 0.3822 to 0.5074. Phylogenetic tree obtained using the subprogram UPGMA of NTSYS represented that Bombyx devided two group, B. mandarina and B. mori. B. mandarina has genetic differences according to the population within the Korean peninsula, but that was not recognized genetic variation or divergence considering low values of genetic distance.
