This study was conducted to investigate the influence of drought stress during the pod developing and seed filling stage on source-sink relationships of soybean (Glycine max). Drought treatments were imposed by withholding water at the full-pod stage, 19 days after flowering, and then limited watering was relieved at 15 days after the initiation of drought treatment. Soybean seed yield was reduced by 39% mainly due to decreased pod number under drought stress, but the 100-seed weight was relatively less reduced. In spite of the 15-day drought during the full-pod stage, soybean produced good seeds showing similar l00-seed weight, protein, starch and soluble sugar content to those from the well-watered. Although drought during the full-pod stage caused source limitations; i.e. accelerated leaf senescence and reduced leaf soluble sugars, it did not cause limitations of other source characteristics such as SGR and leaf starch level. This is because the reduction in size of sinks, such as pod and seed abortions compensated for source limitations, resulting in balanced source-sink as expressed by LAR and the ratio of leaf area to seed dry weight. Drought stress during the pod developing and seed filling stage did not disrupt the source-sink balance

This study was carried out to classify Korean soybean varieties base on maturity group (MG) and to find character relationships according to planting date for high quality soybean seed production adapted to early season cultivation environment of Miryang. Results of maturity grouping of Korean soybean varieties showed that Keunol (3 cultivars), belonged to Group 0; Seonnok and Danmi in Group II, Shinrok in Group III, Seonyu (17 cultivars), in Group IV, Taekwang (44 cultivars) in Group V, Daewon (25 cultivars) in Group VI, and Kwangdu and Keumdu in Group VII. Agronomic characteristics of 100 soybean varieties were compared based on MG, cultivation year and seeding date. Soybean varieties belonging to the MG VI~VII showed longer days to flowering and growth period, high lodging density and higher yield. Seed quality analysis revealed that as maturity was delayed, seed weight becomes heavier while seed cracks become abundant. In addition, occurrence of purple seed and phomopsis were higher in MG 0~III . Protein content was higher in MG 0~III , and isoflavone content was higher as maturity was delayed. On the other hand, lipid content was generally similar across MGs. Correlation analysis of major agronomic characters showed positive relationships between days to flowering and growth days, seed weight and lodging in MG IV~V , seed crack and growth days in MG 0~III , seed crack and days to flowering in MG IV~V and MG VI~VII , seed crack and lodging in MG IV~V and MG VI~VII , seed crack and seed weight in MG IV~V and MG VI~VII , purple seed and growth days in MG IV~V , purple seed and seed weight in MG VI~VII , phomopsis and growth days in MG IV~V and MG VI~VII , and phomopsis and purple seed in MG IV~V and MG VI~VII . In contrast, a negative relationship was observed between seed weight and lodging in MG 0~III . Correlating yield and major characters revealed negative relationships between days to flowering and growth days in MG 0~III and MG IV~V , whereas positive relationships were obtained on MG VI~VII seeded on April 30. Lodging, seed weight and seed crack were all negatively correlated with yield in the MG IV~V and MG VI~VII . Soybean cultivars identified as adaptable to early season planting for production of high quality soy curd and fermented soybean paste were Seonyu, Kwangdu, and Soho while those suited for the manufacture of soybean sprouts were Sobaeknanul, Kwangan, Sowon, and Bosuk. Geomjeong 2 chosen as best for mixing with rice.

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

This experiment was carried out to examine seed quality as affected by enviromental cutivation for the production of high quality domestic soybean variety at Miryang (altitude : 12m) and Muju(altitude : 600m). Variety used were Daewon, Daepung, Daol and Cheongja 3. Seeding was performed on April 30 to June 30 and planting density was 142,857 palnts/ha. Seed weight across regions was lighter as seeding date was delayed. Opposite trends between seed crack and seed weight was obtained. Seed crack decreased as seeding date was delayed and have higher occurrence in Miryang than in Muju. Perple seed and phomopsis decayed seed decreased as seeding date was delayed. There was a significant negative correlation between seed weight and mean temperature from R2 to R4 stages in all variety. Seed weight increased as mean temperature from R2 to R4 stage decreased to 22.0℃, which was greatly manifested on Daewon variety. At maturity time, Daewon variety had an average increase of 1.79g as mean temperature decreased by 1℃. Seed weight of Daewon obtained a significant negative correlation with mean temperature at R4~R6 stage and on rainfall at R4~R6 stage. Mean temperature and rainfall were able to estimate 100 seed weight of Daewon and Daepung variety with 98.1% and 96.6% probability, respectively. Phomopsis occurrence in late maturity type was closely related to rainfall during the R4~R6 stages.
