Manbaekdeulkkae, a vegetable perilla (Perilla frutescens (L.) Britton), was developed by pure line selection from the Kimhae local collection at the National Yeongnam Agricultural Experiment Station, Milyang, Kyungnam. Manbaekdeulkkae is characterized by

"Yujindeulkkae" (Perilla frutescens (L.) Britton) was developed from the cross between "Yeupcildlkkae" and "Sang-jujere" at the National Yeongnam Agricultural Experiment Station, RDA, in 1999. "Yujindeulkkae" can be characterized by dark brown grain color

Two rice varieties, 'Oochikara' with large grain and 'Hwayeongbyeo' and their progenies (F1 , F2 , B1 and B2 ) were tested to understand gene action of morphological traits of rice grain and their relationships. The evaluated traits were 1,000-grain weight, grain length, width, thickness, length-width ratio and chalkiness of brown rice. Correlation between grain weight and chalkiness was highly significant in the all progenies, and grain length were not associated with width and thickness in an F2 population. Scaling test and jonit scaling test revealed that inheritance of grain traits were fitted to additive-dominance model without epistasis. Additive effects for the traits were much greater than the dominance effects.
