The objective of this study was to investigate the variation of Chinese milk vetch(Astragalus sinicus L.; CMV) seed quality after flowering. We tagged individual open flowers of CMV at the day of maximum flowering(11 May) in Seoul, Korea. Seed samples were harvested serially at 15, 20, 25 and 30 days after flowering(DAF). To compare with dried seeds, non-dried seeds were tested immediately after harvest and the remaining seeds were placed at room temperature for 4 weeks. Seed length, 1000 seed weight, moisture content, germination rate(GR), mean germination time(MGT), germination speed(GS), germination performance index(GPI) and physical dormancy rate(PDR) were investigated. Seed length increased to 2.6 mm and 1000 seed weight reached up to 2.2 g until 25 DAF. Seed moisture content dramatically decreased from 20 to 25 DAF. Moisture content of non-dried seed(7.5%) was similar to that of dried seed(5.5%) at 25 DAF. The rate of seed viability reached up to 94% at 25 DAF. In case of dried seed, GR increased up to 39% at 25 DAF whereas GR of non-dried seed varied from 5 to 10%. GS and GPI of dried seed were significantly higher than those of non-dried seed since 25 DAF. PDR of dried seed has decreased since 20 DAF, whereas PDR of non-dried seed has increased. GR, GS and GPI increased as PDR decreased. Our results evidenced that PDR might be one of major factor in variation of seed quality, of which development was completed at 25 DAF.

A new bright white gladiolus “White Lace” was released by the National Horticultural Research Institute (NHRI) in 2004. A cross was made between late flowering white cultivar “White Goddess” and vigorous white cultivar “Amsterdam”. It was crossed in 1999 and finally selected in 2004 after investigation of the characteristics for 5 years from 2000 to 2004. “White Lace” has a bright white color and multi-flowering florets more than 20 florets with good simultaneous flowering more than 8 florets. This cultivar is middle flowering without stem bending. It has good production of cormlets, vigorous growth and resistant to virus, Fusarium and Thrips. The width of “White Lace” flower is 11.5 cm. The plant height is 137cm. Days to flowering of “White Lace” is average 93days in summer season.

“Surabyeo” is a new japonica rice cultivar developed from a backcrossed combination between the F1 of “Suweon 345/ Kanto PL4” and “Suweon 345” of lodging tolerant, semi-dwarf, high-quality rice line by the rice breeding team of National Crop Experiment St
