다양한 용도의 가공용 품종을 육성할 목적으로 1995년 하계에 아밀로스함량이 낮은 일품벼 변이체 Ilpum (MNU)-10-2-GH1-3을 모본으로 하고 양질 내도복성인 서안벼를 부본으로 교배하여 SR21716-30-2-3-1을 선발하여 '수원491호'로 계통명을 부여한 후 2003년-2005년 3개년 간 지역적응시험을 실시한 결과 그 우수성이 인정되어 2005년 12월 직무육성 신품종 선정위원회에서 국가목록등재품종으로 선정됨과 동시에 '백진주1호'로
Baegjinju 1' is a new Japonica rice variety developed from a cross Ilpum (MNU)-10-2-GH1-3 and 'Seoanbyeo' by a rice breeding team of National Institute of Crop Science, RDA, during the period from 1995 to 2005. This variety has heading date of August 23 in central plain area of Korea. It has a good semi-elect plant type and resistance to lodging with strong culm. The number of panicles/hill of 'Baegjinju 1' is more than that of 'Hwaseongbyeo', and milled rice of that shows dull and medium short grain. It has very low amylose content (11.5%) and similar gelatinization temperature and good texture characteristics of cooked brown and milled rice compared with 'Baegjinju'. It has moderate to leaf blast, but susceptible to bacterial blight, virus disease and insect pests. The yield performance of this variety is about 4.92MT/ha in milled rice in local adaptability test for three years (2003-2005). 'Baegjinju 1' is adaptable to central and southern plain areas of Korea.
