초록
‘Chindeul’, a new japonica rice cultivar developed from a cross between HR22538-GHB-36-4 having brown planthopper(BPH) resistance and Iksan471 having a good eating-quality and high yield, was developed by the rice breeding team ofDepartment of Rice and Winter Cereal Crop, NICS, RDA in 2012. This variety has about 124 days growth duration fromtransplanting to harvesting in west-southern coast, Honam and Youngnam plain of Korea. It has 83 cm culm length and toleranceto lodging. In reaction to biotic and abiotic stresses, it shows resistance to bacterial blight pathogen races from K1 to K3, stripevirus and brown planthopper. The milled rice of ‘Chindeul’ exhibits translucent, relatively clear non-glutinous endosperm andmedium short grain. It has lower protein content of 5.9% and good palatability of cooked rice compared with Nampyeongbyeo. The milled rice yield performance of this variety is about 5.61 MT/ha in local adaptability test for three years. ‘Chindeul’ wouldbe useful genetic resources for multi-resistance breeding program against disease and insect.
