Abstract
The major morphological characteristics of 97 lines selected from 1,510 local collection lines of Paeonia spp. were studied and classified into some groups according to their Q correlation. The Coefficient of Variation of 8 characteristics in 97 lines varied greatly with the range from 21.3% to 127.1%. The 22 lines with useful morphological characteristics selected from 97 lines had 2n=10 chromosomes, in which there were no difference among the number of chromosomes of 22 lines. The 97 lines were classified into 14 groups based upon the results of Q correlation analysis obtained from data with 16 quantitative factors; Group III and group VI were divided into two sub-groups. Group I was large flowered lines with a single flower, Group IIIa, doubled flowered lines, Group VII, late maturing lines and Group IX, early maturing lines flowering in 17th May. Group VIII were dwarf type lines which has the shortest stem length and leaf length among 14 groups, which are suitable for potted plants. Group XIII had a lot of stems per plant and a large type leaf with leaf length and width. A needle-type leaf was found in Group X, whereas a wide and oval-type leaf in group XII.
작약의 지방수집종 1,510계통 중에서 선발된 97계통의 주요 특성을 조사 분석한 다음 Q 상관에 의해서 계통분류한 결과 97계통에서 주당엽수, 엽폭, 엽병장, 화사수, 주두수, 화판수. 화장, 개화기 등의 8개 형질에서 계통들 간에 변이계수가 21.3 - 127.1%로 상당히 큰 것으로 나타났다. 97계통 중 외부 형질이 유망한 22계통의 염색체수는 2n=10으로 계통간에 염색체수의 이상을 발견할 수 없었다. 97계통의 16개 양적형질에 대한 Q 상관관계를 분석한 결과 14개 계통군으로 분류되었고, 제III군과 제VI군은 다시 각각 2개의 아군으로 분류되었다. 제 I 군은 홑꽃계통으로 화폭과 화장이 큰 대륜종이며, 제
