‘Mipum’ is a new japonica rice variety developed and registered by the rice breeding team of Department of Rice and Winter Cereal Crop, National Institute of Crop Science, Rural development Administration in 2010. This variety was derived from the across between ‘Koshihikari’ with high grain quality and the F1’s crossed Gyehwa21 and ‘Junam’ with resistance to diseases and good eating quality. This variety has about 127 days growth duration from transplanting to harvesting in west-southern coast, Honam and Youngnam plain of Korea. It is about 77 cm in culm length and tolerance to lodging. In reaction to biotic and abiotic stresses, it shows moderately resistance to blast, and resistance to stripe virus, however it is susceptible to bacterial blight races from K1 to K3 and other major diseases and insect pests. The milled rice of ‘Mipum’ shows translucent,relative clear non-glutinous endosperm and medium short grain. It has higher amylase content of 20.1% and lower protein content of 6.6%, and better palatability of cooked rice compared with ‘Nampyeongbyeo’. The milled rice yield performance of this variety is about 5.64MT/ha in local adaptability test for three years. ‘Mipum’ would be adaptable to Honam and Youngnam plain of Korea.
