초록
‘Bbareumi’ is an extremely early maturing rice cultivar with the fastest harvesting time in Korea. To develop ‘Bbareumi’, ‘Joami’with good quality in Chungnam plain area and ‘Hokuto’ originating from Japan with the fastest heading date among genetic resources wereused as breeding materials. After crossing them in 2010, the ‘Bbareumi’ cultivar was developed using the pedigree method. A yield trialwas conducted from 2015 to 2016, and a local adaptability test was conducted from 2016 to 2018. The heading date of ‘Bbareumi’ wasseven days earlier than ‘Jinbuolbyeo’, showing an average of June 23rd, and it could be harvested from the end of July to the beginningof August when transplanted early in Chungnam plain area. ‘Bbareumi’ had a short culm length of 63.3 cm and panicle length of 19.3 cm. Milled rice yield was approximately 4.87 MT/ha and the percentage of head rice was 89.2% under normal fertilizer condition. ‘Bbareumi’will be used as a premium rice brand with newly harvested rice before ‘Chooseok’, Korean Thanksgiving Day and is expected to contributeto the revitalization of double-cropping in the Chungnam plain area (Registration No. 8130).
