The importance of wild plant resources along with the development of high biotecyhnology is highlighted for exploitation of new materials which can make the added value. The goal of this study is providing fundamental data bases for developing new materials through the analyses of morphological characteristics, antibiotics and molecular cytogenetics in Baegseon (Dictamnus dasycarpus Turcz.). Baegseon has several characteristics; there are two types of flower color, pink and white, the seed germination starts about February 20th, the maximum flowering season is around May 17th in southern Korea, the growth period is about 60 days. The number of chromosomes are 2n=2x=36, the size of chromosomes in metaphase is $4.2{\sim}8.1{\mu}m$. The amount of 2C nuclear DNA is 1.93pg, and there is no variation of genome size amoung varieties. The extraction juice of baegseon young roots has the excellent antibiotic activity against the mold (Botrytis cinerea).
