우리나라 미나리(Oenanthe javanica DC)의 系統分類에 關한 硏究 = A Study on the Strain Classification of Korean Water Dropwort(Oenanthe javanica DC)

다국어 초록 (Multilingual Abstract)

This paper was an attempt to collect the water dropworts of 80 strains throughout the country and to classify them by quantitative character for the strain classification of them in this country.
1. The genetic variation of quantitative character between strains was widest in plant height, runner lenght, and leaf length. They could be classified into 13 strain groups by Mahalanobis's D²classification. In the strain number of each classified group, the 6th group was greatest in number(11strains), and the 2nd, 10th, 13th group were least (2strains).
2. According to their main characters the classified strain groups by genetic distance could be divided into tall, medium and small strains in plant height, and into early, medium, and late strains in days to flowering.
3. The most influential main characters in classifying strain group were plant height, runner length, and leaf length, and the least influential characters were stem node and top leaflet index.
