Characteristics of Important Agronomic Traits of Korean Local Soybean Collections

782 local soybean lines currently grown by Korean farmers were collected in the Korean peninsula and studied their important agronomic traits for two years grown at the Experimental Farm of the Korea Atomic Energy Research Institute in Seoul. About 13 percent of these collected lines have produced seeds over 1,000㎏ per hectar and some of them wee apparently superior to the leading varieties grown in the identical conditions. Maximum seed size within this collected population was 42.4g per 100 seeds and 17 percent of this population posesses of seed size over .30 g/100seed. 66 percent of the population was belong to the maturity group IV and V and maturity group 00 and over VII were not found from the collection. Plant height was ranged from 126㎝ to 45㎝ and frequency distribution for plant height shows normal curve. Seed yield possitively correlated with seed size, while negatively associated with flowering, maturity, and plant height.
