Cheongpum had a culm length of 79 cm, which was 5 cm shorter than that of Hwaseong, and 116 spikelets per panicle. The viviparous germination rate of Cheongpum was 27.9%. It showed resistance to blast, bacterial blight (K1, K2, K3 race), and stripe virus, but susceptibility to the K3a race of bacterial blight, dwarf, and black streak dwarf viruses, and plant hoppers. The milled rice of this variety exhibited a translucent and medium short grain shape. The cooked rice grains of Cheongpum had an excellent palatability index (0.41) and lower amylose content (18.8%) than that of Hwaseong. The grain milling characteristics were better than those of Hwaseong, especially the head rice milling recovery ratio and head rice ratio (94.1%). Cheongpum showed 5.36 MT/ha of milled rice productivity at 11 sites under ordinary cultivation (Registration No. 6799).

2 韓育誌 (Korean J. Breed. Sci.) 50(3), 2018 있어서농약의살포를줄일수있는복합내병성품종의개발이나도복저항성등내재해성품종의개발이중요한목표로대두되고있다. 중부지역재배에적합한복합내병성및내재해성벼품종은중만생종인최고품질품종인 삼광 (Kim et al. 2007), 중생종으로는줄무늬잎마름병에저항성인 화성 (Moon et al. 1986) 과 중생골드 (Cho et al. 2013) 품종이재배되고있다. 본논문은중부지역작부체계에적합한출수생태형인중생종이면서복합내병성이고도복에강하고밥맛이아주우수한 청품 을개발하였기에품종의육성경위및주요특성을보고하고자한다. 재료및방법본시험은 청품 를 2013 ~ 2015년 3년간중부평야지 6개지역과남부중산간지 3, 동남부해안지1, 중서부해안지 1개등 11개지역에서보통기보비재배로대비품종인 화성 과비교하여지역적응성시험을수행하였다 (RDA 2014a, 2015a, 2016). 중부평야지는 4월 25일에파종하고, 5월 25일에재식거리 cm로주당 3본씩이앙하였으며, 남부중산간지및중서부해안지에서는재식거리를 cm로주당 5본씩이앙하였다. 시비량은 N-P 2O 5-K 2O를각각성분량으로 kg/10a을시용하였다. 질소는기비로 50%, 추비로분얼비 20% 와수비 30% 로 3회에걸쳐분시하였고, 인산은기비 100% 로시용하였고, 칼리는기비 70%, 수비 30% 로나누어시용하였다. 벼잎도열병검정은 14개지역에서밭못자리상태로파종하여 30일후계통들의이병 정도를조사하였다. 흰잎마름병은 K1(HB1013), K2(HB1013), K3(HB1013) 및 K3a(HB1009) 균계를포장에서최고분얼기에개체별로가위절엽접종하여 30일후에이병정도를조사하였다. 유묘바이러스검정은본엽 2~3엽기에보독충접종을 3~4일간실시하고, 접종후 30일에조사하였다. 재해저항성중수발아검정은출수후 40일에이삭을채취하여 25, 포화습도에서발아율을검정하고, 내냉성검정은시험계통을이앙후 20~30일부터등숙기까지 17 의냉수처리하여임실율등을조사한다. 기타농업형질, 수량구성요소, 수량성및도정특성의조사분석이나시험포장의재배관리는농촌진흥청에서발간한신품종개발공동연구사업계획서에준하여실시하였다 (RDA 2013, 2014b, 2015b). 결과및고찰육성경위 청품 은중부지역에서재배하기적합한고품질품종을육성할목적으로 2006년하계에쌀의외관품위가매우좋으며도복에강한중생종 영덕45호 (IT235286) 와흰잎마름병에저항성이며밥맛과도정특성이우수한중만생최고품질품종 삼광 (IT284608) 를인공교배하여교배번호 SR31110을부여한후, F 1 세대 43개체를양성하였다. F 1 세대에서꽃가루배양을실시하여 HB3028번호를부여하고 AC 1 세대에서 200개체를양성하였다. AC 2 세대에서 184계통을전개하여단간이며숙색이우수한 3계통을선발하 z PYT: Preliminary yield test y RYT: Replicated yield test x LAT: Local adaptability test Fig. 1.
