영문 초록

The soybeans, currently grown by Korean farmers, have been grown for many centuries without artificial improvement and it may result an accumulation in abundance of variances. In order to collect the gene sources and to select superior lines from the land races, a continuous collection was made in all part of the country and planted on line bases to study the character and interrelationships among the characters. The average flowering dates were 67 days in the collected population which is earlier than the one studied in the named local varieties. High correlation coefficient was observed between flowering and maturity. Negative correlations between seed yield and maturity or flowering were found, which is contradictory to other reports. The maturity of this population was ranged from 106 days to 151 days and highly correlated with plant height, number of nodes per plant and seed weight. Average plant height in the collected population was small as compare to the average height of named local varieties. Variance for lodging and disease were relatively large. Consequently, there are some possibilities to obtain useful gene sources for resistant to lodging and diseases. Protein content showed negative correlations with oil content, seed yield, flowering and seed weight, whereas positive correlations with plant height and maturity were observed. Since the small plot size for yield estimate the result was not fully reliable, but the relative seed yield among the collected lines ranged from 60 to 3,484 ㎏/㏊ and it is meaningful in breeding for high yielding varieties.
