To fit the market demands for functional rice such as black and red color rice, ‘Sugary’a high free sugar content line was backcrossed to the black rice ‘Milyang152. The pedigree method was adapted in selection and generation advance. A high polyphenol content line, YR19646-3-2-1-1-2-2 showing red pericarp was selected and designed as ‘Milyang234’ followed by variety name ‘Geonganghongmi’ in 2010. Heading date of ‘Geonganghongmi’ was Aug. 19, medium-late maturing cultivar. ‘Geonganghongmi’ showed resistance to leaf blast and rice stripe virus while susceptible to major diseases and insects. The total polyphenol content of ‘Geonganghongmi’ was high as much as 24.2mg/g compare to that of 4.9mg/g of ‘Nampyeongbyeo’ and 17.2mg/g of a red pericarp rice ‘Jeogjinju’ at 70% ethanol extraction conditions. In local adaptability tests, yield of ‘Geonganghongmi’ was 4.5MT/ha about 86% of ‘Nampyeongbyeo’ and 102% of ‘Jeogjinju’, respectively. ‘Geonganghongmi’ is suitable for southern and middle plain area of Korea.

A new peanut variety ‘Boreom1’ (Arachis hypogaea ssp. fastigiata.) was bred at the Department of Functional Crop, NICS, in Milyang in 2010. This was developed by pedigree method after the cross between the large grain cultivar ‘Suwon 108’ and the short stem cultivar ‘Milyang4’. ‘Boreom 1’ which is Shinpung plant type had 9 branches per plant and its length of main stem was 43 cm. Each pod has two grains with brown testa and long ellipse-shaped large kernel, and its 100 seed weight was 105 g in the regional yield trials (RYT). ‘Boreom1’ showed 49.9% of crude oil and 54.5% of oleic acid composition in dry seed, and had 30.8 mg/g of sucrose and 4.2 mg/g of tannin content in fresh peanut. In the regional yield trials, ‘Boreom 1’ was more productive than reference variety by 8% with 10.16 MT/ha for fresh pod production and by 3% with 4.26 MT/ha for dry grain production.
