초록
To fit the market demands for functional rice such as black and red color rice, ‘Sugary’a high free sugar content linewas backcrossed to the black rice ‘Milyang152. The pedigree method was adapted in selection and generation advance. A highpolyphenol content line, YR19646-3-2-1-1-2-2 showing red pericarp was selected and designed as ‘Milyang234’ followed byvariety 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 totalpolyphenol content of ‘Geonganghongmi’ was high as much as 24.2mg/g compare to that of 4.9mg/g of ‘Nampyeongbyeo’ and17.2mg/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’ issuitable for southern and middle plain area of Korea.
Abstract
To fit the market demands for functional rice such as black and red color rice, ‘Sugary’a high free sugar content linewas backcrossed to the black rice ‘Milyang152. The pedigree method was adapted in selection and generation advance. A highpolyphenol content line, YR19646-3-2-1-1-2-2 showing red pericarp was selected and designed as ‘Milyang234’ followed byvariety 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.
