영문 초록

Petiole length of soybean is believed to be closely related to lodging and other agronomic characters, however, there have been few studies on it. Determination of representative petiole length from soybean plants is difficult because of the variation of petiole length at each nodes. This study was to determine the representative petiole length from soybean genotype, and relationships between petiole length and other agronomic characters. The petiole of the lower first node was the shortest and became gradually longer on upper nodes in determinate type. Any petiole of 4th to 15th nodes from top could be used as the representative ones, while the average of three petioles from top third to 5th taken at flowering terminate stage or the measurement from the sixth petiole from the top could be also used as the representative. Petiole length showed highly significant positive correlation with the flowering, maturity, and ripening period, but negative correlations were found with 100 grain weight and pod borer damage. One of the reasons for the lodging of Korean native soybeans seemed to be due to their long petioles, and the importance of petiole length in soybeans was fully recognized.
