들깨 수량에 영향하는 형질을 정확히 알기 위하여 형질상호간의 상관관계와 경로계수를 분석한 바 그 결과를 요약하면 다음과 같다. 1. 경장은 경식경, 화방수, 경중과 유효분지수는 화방수와 높은 정의 상관을 그리고 유효분지수는 1,000입중과 화방수는 1,000입중과 각각 높은 부의 상관을 보였다. 2. 수량에 직접적으로 영향하는 형질은 경중, 화방수 1,000입중 유효분지수, 경직경등이다. 3. 간접적 효과는 경장대 경중, 유효분지수 대 화방수, 화방수 대 경중간에 높은 값을 보였다. 4. 들깨의 수량은 경장이 길고 유효분지수 및 화방수가 많으며 1,000입중과 경중이 무거운것일수록 수량이 많다는 사실을 알수 있다.
In order to clarify the relationship between the characters and the influence of each character on the yield of perilla, correlation coefficients and path coefficients were calculated. The results obtained are summarized as follows; 1. A highly significant positive correlation was found between stem length and stem diameter, number of pods per plant, stem weight, respectively. Number of internodes showed also significant positive correlation , with number of pods per plant, stem weight, respectively as well as the relationship between number of valid branches and number of pods per plant. On the other hand, a significant negative correlation was appeared between number of valid branches and l000-grain weight as well as the relationship between number of pods per plant and l000-grain weight. 2. It seemed to be clear that stem weight, number of pods per plant, l000-grain weight, number of valid branches and stem diameter have direct and positive influence on the yield of perilla. 3. Indirect influence was observed between stem length and stem weight, between number of valid branches and number of pods per plant, and between number of pods per plant and stem weight, respectively. 4. It may be concluded that the yield of perilla is positively correlated with stem length, number of valid branches, number of pods per plant, l000-grain weight and stem weight.
