Happymi is a new sweetpotato variety developed from Mokpo Experiment Station, National Institute of Crop Science(NICS), RDA in 2004, which was for the raw eating and processing. This variety was selected from the cross between Chinmi andMA 3 in 1996, seed

Biomi is a new sweetpotato variety developed from Mokpo Eeperiment Station, National Honam Agricultura iment Station (NHAES), RDA in 2003, which was for the utilization as feed and food for storage root ofhigh moisture content andfast fleshed up. This var

“Younbaek”, a new noodle making wheat cultivar, was developed from the cross between “Keumkang” with white grain color and “Tapdongmil” by the Honam Agricultural Research Institute(HARI), National Institute of Crop Science (NICS), RDA, Korea in 2005. Amon

“Jokyoung”, a new bread making wheat cultivar, was developed from the cross between “Seri 82”, a hard white wheat from CIMMYT, Mexico and “Keumkang”, a hard white wheat with high milling rate and early maturing from Korea by National Institute of Crop Sci

This study was to verity that the uptake inhibition and accumulation of nitrogen in different potassium levels. Lettuce was used as model plant in this study and grown in pot of 10cm's in diameter and depth with mixture media of vermiculite and perlite under supply of different culture solution for three weeks. Nitrogen absorption at root was inhibited by increased potassium concentration in nutrient solution, and nitrate accumulation of plant was depended on absorption of nitrogen because nitrate content of 0 K level was 4-5 times higher than that of 2 K level, Concentration of ascorbic acid was decreased by increasing the nitrogen absorption, since ascorbic acid (AsA) content of 2K level was higher than those of OK level in both of old leaf and flesh leaf

‘Jopummil’ was bred from the cross between SW88416-B-0 with the early maturity and short culm, and the F1 hybrid between OR8500494P and “Bezostaya” in 1990. It was examined as ‘Suwon 284’ in the regional yield trials(RYT) from 1999 to 2001. It was a near-

‘Okjeon’ rye (Secale cereale L.) was developed by the National Crop Experiment Station (NCES). It was released in 2001 because of its excellent earliness and yield potential. ‘Okjeon’ was developed from an open pollination with 20 rye lines in 1984. Subse
