This study was conducted to characterize mulberry varieties by the analysis of morphological characters as well as biochemical and molecular biological markers. As for the budding stage Geumsang, Chosang i and Yeongbyeonchuwoo were early, but Dangsang 6, Hwangchuwoo were late. The lowest varietiy in rate of death atop was Dangsang 8(0.0%). Suncheonppong was the highest leaf yields in spring and autumn rearing season. In biochemical isozyme analysis, peroxidase gave good zymogram patterns in isoelectric focusing electrophoresis. There were high variations in RAPD analysis among the mulberry trees. From the obtained peroxidase and RAPD variations, cluster phylogenetic analysis was carried out using NT-SYS PC program. There were no clear grouping patterns between native varieties and leading varieties. The highest similarity was observed between Suwonsang 1 and Suwonsang 2 at about 90% similarity level.
