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

Wild rices are an important source of useful genes for resistance to diseases, insect pests, tolerance for abiotic stresses and yield increase. O. minuta (BBCC), a tetraploid wild rice having 48 chromosomes, was used for the cross with japonica rices. Fer

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.
