‘까리1호’는 내병, 내도복의 아주까리콩 품종육성을 목표로 2009년에 ‘청자3호’를 모본으로, 재래 아주까리콩인 ‘IT105279’을 부본으로 교배하여 계통육종법에 의해 선발되었다. 2016년부터 2017년도에 실시한 생산력검정시험에서는 다수성 내도복 아주까리콩 계통으로 유망하여 ‘밀양350호’의 계통명을 부여하였고, 2018년부터 2020년까지 3년간 7개소에서 수행한 지역적응시험 결과 쓰러짐과 불마름병에 강한 특성을 나타내어 ‘까리1호’로 명명하였다. ‘까리1호’ 유한신육형, 엽형이 둥근형, 화색이 보라색이며, 검은색 종피에 그물무늬가 있다. 개화기는 8월 3일, 성숙기는 10월 23일로 ‘청자3호’와 개화기와 성숙기가 비슷하며, 100립중이 32.7 g으로 ‘청자3호’ 대비 다소 가볍다. 도복 정도는 지적 7개소 시험포장과, 검정포장에서 ‘2’로 평가되어 ‘청자3호’ 대비 강하였고, 탈립성 정도는 실내 검정에서 ‘청자3호’에 비해 낮아 탈립에 강하였다. 불마름병에 ‘청자3호’와 대등하여 강하였으나, 콩모자이크바이러스 접종 시 괴저 증상이 나타났다. ‘까리1호’는 ‘청자3호’ 대비 조단백, 조지방이 비슷하고 당 함량은 다소 낮았으며, 주요 기능성 성분인 이소플라 본 함량이 ‘청자3호’ 대비 높았다. 수량성은 전국 7개 지역 평균 252 kg/10a로 ‘청자3호’보다 4% 증수되었다.

‘Kkari1ho’ is a net-like, cracking-patterned seed-coated soybean cultivar developed from a crossing of ‘Cheongja3ho’ and ‘IT105279 (landrace)’ in 2009. The F1 and F2 populations were grown for two years, and promising lines were selected using the pedigree method from F3 to F5. A preliminary yield trial (PYT) and an advanced yield trial (AYT) were conducted from 2016 to 2017, and a regional yield trial (RYT) was conducted in seven regions from 2018 to 2020. ‘Kkari1ho’ is determinate, has an oval leaflet shape, purple flowers, and net-like cracking-patterned seeds. The flowering and maturation dates were August 3 and October 23, respectively. For quantitative characteristics, ‘Kkari1ho’ had a smaller seed weight (32.7 g/100 seeds), while its plant height and first pod height were similar to those of ‘Cheongja3ho.’ While ‘Kkari1ho’ was highly resistant to lodging under standard field conditions, its lodging resistance tended to decrease in high-density plots. Regarding pod shattering, ‘Kkari1ho’ exhibited higher resistance than ‘Cheongja3ho’ in both RYT field and indoor tests. ‘Kkari1ho’ showed comparable resistance to bacterial pustule to that of ‘Cheongja3ho’ in both field and artificial inoculation tests. In contrast, its resistance to soybean mosaic virus (G6H strain) was lower in inoculation tests but comparable in field tests. The mean yield of ‘Kkari1ho’ in the RYT was 252 kg/10a, which was a 4% higher mean yield across the region than that of ‘Cheongja3ho.’ ‘Kkari1ho’ is expected to replace landraces due to its resistance to lodging and bacterial pustule (Registration number: 9450).
