A Mid-late Maturing Rice Cultivar with High-Quality and Bacterial Blight Resistance "Jinbaek"
pp.314-318
"진백"은 국립식량과학원 벼맥류부에서 2008년도에 육성한 중만생 고품질 벼흰잎마름병 신균계, K3a 저항성 품종으로 주요특성과 수량성을 요약하면 다음과 같다. 1. 남서해안지, 호남 및 영남평야지 보통기 보비재배에서 평균 출수기가 8월 18일로 남평벼보다 1일 늦은 중만생종이다. 2. 간장은 71 cm로 '남평벼'에 비해 8 cm 정도 작고 주당 수수는 남평벼와 비슷하며 수당립수는 적고 등숙비율이 다소 높은 중립종에 속한다. 3. 위조현상은 나타나지
A new rice cultivar "Jinbaek" carrying Xa3 and xa5 was derived from the cross between 'HR15204-38-3' with xa5 gene resistant to bacterial blight K1, K2, K3 and K3a, and F1 plant derived from the cross between Junam and Sindongjin with Xa3 gene. "Jinbaek" has approximately 125 days of growth duration from transplanting to harvesting in the west-southern coastal and Honam plain of Korea. Culm length of "Jinbaek" is 71 cm. In reaction to biotic stresses, it shows moderate resistance to blast, and wide spectrum resistance to bacterial blight pathogen, K1, K2, K3, and K3a but susceptible to rice stripe virus and blast. The milled rice of "Jinbaek" exhibits translucent, relatively clear non-glutinous endosperm and midium short grain. It has lower amylose content (18.8%) and protein content (6.2%) compared with Nampyeong. The milled rice yield of this cultivar was 5.30 MT/ha in local adaptability test of three years from 2006 to 2008. This cultivar would be adaptable to the bacterial blight-prone area in the south-western coast and Honam plain of Korea.
