‘Dabokchal, a glutinous rice variety (Oryza sativa L.) with a medium late maturation period was developed by the Departmentof Crops and Food, JARES in 2020. It was derived from a cross between the glutinous cultivar ‘Shinmyeongheugchal’ with the good glutinousproperties and ‘Hwangkumnodeul’ as a high yielding source. The progenies of the cross were selected by bulk and pedigree breeding methoduntil the F8 generation. As a result, a promising line, JR53-28-4-10-5-3, was advanced and designated as the name of ‘Jeonbuk12’ in 2018. The ‘Jeonbuk12’ local adaptability test was carried out at four locations during 3 years from 2018 to 2020. This variety headed on August13, which was eight days later than ‘Sinseonchal’ in Honam plane. The culm and panicle length of this variety was 70 cm and 22 cm, respectively. This variety has about 16 tillers per hill and 92 spikelets per panicle. The ratio of ripened grain is approximately 84.9% and 1000-grainweight was 24.9 g in brown rice. This variety has a higher amylose content compared to that of ‘Sinseonchal’. The yield performance ofbrown rice was 591 kg/10a in the local adaptability test. This cultivar is considered to be adaptable to the Honam plain area of Korea (RegistrationNo. 9602).
