A new soybean cultivar for soy-paste, “Mansu”, was developed from the cross between ‘Suwon 192’, which was tolerant to disease, late maturing and high yielding, and ‘Suwon 196’ which was early maturing and large seed by soybean breeding team in the Yeongnam Agricultural Research Institute (YARI) to make new variety having large seed and high yielding. A promising line, SS97213-2B-3SSD-39-1-1, was selected and designated as the name of ‘Suwon 236’. It was characterized by regional yield trials (RYT) for three years from 2004 to 2006 and released as the name of “Mansu”. It has a determinate growth habit, purple flower, grey pubescence, pale green seed coat, yellow cotyledon, large spherical seed (26.5 grams per 100 seeds). Maturity date is 4 days later than the check cultivar, Taekwang. The average yield of Mansu was 2.93 ton per hectare in the regional yield trials (RYT) carried out for three years from 2004 to 2006 which was 7 percent higher than that of the check cultivar, Taekwang.

A new mungbean cultivar Soseon (Vigna radiata (L.) Wilczek) was derived from the cross between KM9003-2B-783 and V2939 at the Jeollanam-do Agricultural Research & Extension Services (JARES) in 2003. “Soseon” has erect growth habit, heart leaf, green hypoc

A new mungbean variety Samgang (Vigna radiata (L.) Wilczek) was improved from the cross between Keumseongnogdu and V2939 at the Jeollanam-do Agricultural Research & Extension Services (JARES) in 2002. Samgang has erect growth habit, lobed leaflet, green h

Fifty-four Korean native and 28 foreign rice varieties harvested in 1998 and 1999 were examined for antioxidative activity that is measured to a chemiluminescence and superoxide radical intensity, by the flow injection chemiluminescence (FI-CL) system and an electron spin resonance (ESR) spectrophotometer, respectively. In the chemiluminescence measurement by FI-CL, radical scavenger activity did not differ significantly among rice varieties between origin types of rice varieties, and between storage periods. GinSun and Hongchoengdo, colored rice exhibited high electron scavenging effect by ESR. Therefore, these results indicate that the pigments of rice varieties may play important antioxidative roles and that it may be possible to breed rice varieties with higher antioxidative potentials.

Sixty local soybean cultivars were evaluated on the antioxidative activity by superoxide dismutase (SOD), 1, 1-diphenyl-2-picrylhydrazyl (DPPH), thiobarbituric acid(TBA), and chemiluminescence using the FI-CL system. Soybean were collected throughout the country, and were grown over two years (1997 and 1998) for measuring antioxidative activity in soybean seeds. There were differences in antioxidative activity depen-ding on the method of measurement and variation of the crop year. Soybeans from Kwangyang-shi-1 (76.78%) in 1997 and Kangjin-gun-3(79.14%) in 1998 showed the highest SOD activity, whereas those from Hwasoon-gun (80.43%) in 1997 and Kangjin-gun-2 (49.82 %) in 1998 exhibited the highest DPPH activity. Soybeans from Chongup-gun-2 (75.77%) in 1997 and from Yochon-shi-5 (69.17%) in 1998 exhibited the highest TBA activity, and those from Jinahn-gun (48.99%) in 1997 and Kohung-gun (49.73%) in 1998 exhibited the highest activity using the chemiluminescence method. These results suggest that it may be possible to develop soybean varieties with higher antioxidative activity
