Abstract
In order to find out a high potential black soybean lines, of which demand has been increasing in Korea, twenty eight local cultivars were evaluated on agronomic characteristics and the classification of the cultivars was made by the cluster analysis. Days to maturity and days to growing of black soybeans were widely ranged from 58 to 82 days, and 117 to 148 days, respectively. Late maturing group showed over 140 maturity days, and heavy 100 seed weight. There was shown low yield potential in late maturing group, and growing days was positively correlated with flowering days, days to maturity, 100-seed weight and stem length, respectively. From the principal component analysis upper two components composed 76.5% cumulative eigen value to total. Nine varietal groups were identified in relations to their affinity of the black soybeans. Selected black soybeans, Namhae-2 and Hamyang-l were field-tested and those characteristics of many pod, small seed and high yield were found out to be suitable for sprouting.
본 시험은 최근 수요가 증가하고 있는 검정콩에 대한 특성을 조사하고 우량계통 육성을 위한 기초자료를 얻고자 수집한 검정콩 28개 재래종에 대하여 주성분 분석에 의한 품종군 분류와 품종군별 생산적 검정을 한 결과를 요약하면 다음과 같다. 1. 수집 검정콩의 결실일수는 58∼82일, 생육일수는 117∼148일로 변이폭이 컸으며, 결실일수와 생육일수가 길어질수록 100립중이 무거워지는 경향이었다. 2. 만숙군에서 비율이 낮았고, 생육일수는 개화일수, 결실일수, 100립중, 경장, 분지수 등과는 각각 정의 상관을 나타내었다. 3. 주성분분석 결과 상위 2개의 주성분만으로도 전체 변동의 76.5%를 표시할 수 있었으며, 품종간 유연도를 나타내는 single link cluster 분석으로 28개 수집재래종을 9개의 품종군으로 분류할 수 있었다. 4. 품종군 분류에 의해 다협, 소립, 다수성인 남해 -2, 함양-1을 나물콩용으로 선발하였다.
