This study was carried out to obtain general agronomic characteristics and identify its relationship with seeding date for high quality soybean seed production. One hundred(100) domestic soybean varieties were used and seeding date were scheduled at April 30 and May 30. This experiment was carried out at YARI, NICE situated at Miryang from 2005 to 2006. Maturity Group(MG) was classified by Kweon et al's method (1974). Correlation analysis of major agronomic characters showed positive relationship between days to flowering and growth days, seed weight and lodging in MG ,seed crack and growth days in Ⅳ～Ⅴ MG0～Ⅲ,seed crack and days to flowering in MGⅣ～Ⅴ and MGⅥ～Ⅶ, seed crack and lodging in MGⅣ～Ⅴ and MGⅥ～Ⅶ, seed crack and seed weight in MGⅣ～Ⅴ and MGⅥ～Ⅶ, purple seed and growth days in MGⅣ～Ⅴ , purple seed and seed weight in MGⅥ～Ⅶ, phomopsis and growth days in MGⅣ～Ⅴ and MGⅥ～Ⅶ, and phomopsis and purple seed in MGⅣ～Ⅴ and MGⅥ～Ⅶ. In contrast, a negative relationship was observed between seed weight and lodging in MG0～Ⅲ. Correlating yield and major characters revealed negative relationship between days to flowering and growth days in MG0～Ⅲ and MGⅣ～Ⅴ, whereas positive relationships were obtained on MGⅥ～Ⅶ seeded on April 30. Lodging, seed weight and seed crack were all negatively correlated with yield in MGⅣ～Ⅴ and MGⅥ～Ⅶ
