우리나라의 재래종 대화형 대두인 부채콩의 생육 및 형태적 특성을 정상형 대두인 단엽콩과 비교하였던 바 그 결과를 요약하면 다음과 같았다. 1. 대화형 대두인 부채콩의 주경은 생육이 진행됨에 따라 대화가 심해졌고 정상형인 단엽콩에 비해 출엽이 불규칙하였으며 주경엽수는 단엽콩보다 훨씬 증가하였으나 총엽수는 크게 다르지 않았다. 2. 부채중의 주경대화정도는 약 3.1정도였으며 대화정도는 정상형인 단엽콩의 주경과 분핵의 생육량과 유관하였다. 3. 부채콩의 분지수는 단엽콩보다 적었으나 분지가 대화하는 경우도 있었으며 엽병의 대화도 관찰되었다. 4. 부채콩은 협의 대부분이 주경 선단부에 집중 분포하였다. 5. 부채콩의 수량은 단엽콩의 60％정도였으며 수량감소의 주원인은 종실중과 협당입수의 감소였다. 6. 주경 횡단면의 유관속수는 부채콩이 많았으나 각 유관속은 단엽콩이 발달하였다.

This experiment was carried out to obtain some information about the growth habit and morphological and anatomical characteristics of fasciated soybean, var. Buchai-kong. The results obtained are summarized as follows: 1. Main stern of fasciated soybean, var. Buchai-kong was gradually broadened and became flat, on which leaves emerged irregularly compared with normal soybean, var. Danyeop-kong. The number of leaves on main stern was more in Buchai-kong, but the total number of leaves per plant was not considerably different each other. 2. The degree of fasciation (max./min. in diameter at the broadened part) in main stern of Buchai-kong was about 3.1, and was related to the amount of growth of main stern and branches of Danyeop-kong. Stern fasciation types found in Buchai-kong were linear (the most common) and bifurcated with regard to branching of main stern tip. 3. The number of branches per plant was much less in Buchai-kong than in Danyeop-kong. There were fas-ciated branches and fasciated petiole in Buchai-kong. 4. About 75 percent of pods of Buchai-kong were concentrated on the top of stern, which showed strong pod clustering. 5. Seed yield per plant of Buchai-kong was about 60 percent of that of Danyeop-kong, and the decrease in seed yield was mostly affected by the decrease in seed weight and seeds per pod. 6. The number of vascular bundles of transection of mature stern was more in Buchai-kong, but Danyeop-kong developed the better vascular bundle.
