Abstract

The correlations between growth charateristics and root yield were investigated in 74 peony lines collected from chief producing place in Korea. Among these peony lines, single flower type was 61% and the rest were double type. And pink flower was in majority. Stem length, stem diameter and number of stem per plant were $50{\sim}60cm$, $7{\sim}8mm$ and $5{\sim}6$, respectively. Generally, disease tolerance and root yield were better in single flower type peonies than double type. Among single flower type peonies, the correlation coefficients between each characteristics and root yield were as follows : number of stem $(0.676^{**})$, number of roots $(0.646^{**})$, stem length $(0.617^{**})$, root diameter $(0.590^{**})$ and root length $(0.443^{**})$. Correlation between root yield and paeoniflorin content was highly significant $(0.383^{**})$ among single flower type peonies and significant $(-0.382^*)$ among double flower type peonies. Correlation between stem diameter and root yield was not significant (0.066).

작약(芍藥)의 육종재료(育種材料)로 이용되는 유전질원(遺傳資源)의 수집(蒐集)과 활용시(活用時) 외관(外觀)의 형태적(形態的) 특성(特性)과 지하부(地下部) 약근수량(藥根收量)과의 상호(相互) 상관(相關)을 조사한 결과(結果)는 다음과 같다. 1. 약재용(藥材用)으로 수집(蒐集)된 74계통중(系統中) 홑꽃이 61%였으며 겹꽃은 39%로 홑꽃이 주를 이루었다. 2. 경장(經長)은 주로 $50{\sim}60cm$였으며 줄기직경은 $7{\sim}8mm$, 줄기수는 $5{\sim}10$개 범위에 분포가 가장 많았다. 3. 수집계통중(蒐集系統中) 내병성(耐病性)이 매우 강(强)한 계통은 3계통(系統)이었고, 주당(株當) 뿌리 수량이 90 이상(以上)인 화형은 홑꽃이 많았다. 4. 뿌리수량(收量)과의 상관(相關)은 홑꽃은 경장, 경수, 근장, 근직경, 근수, 겹꽃은 경장, 경수, 근직경, 근수와 각각 고도(高度)의 정상관(正相關)을 보였다. 5. 뿌리수량(收量)과 pareniflorin 성분함량(成分含量)과는 홑꽃에서 고도(高度)의 정상관(正相關)이었으나 겹꽃에서는 부(負)의 상관이 인정(認定)되었다.
