Abstract

'Aram' is a soybean cultivar developed for soy-sprout. It was developed from the crossing of 'Bosug' (Glycine max IT213209) and 'Camp' (G. max IT267356) cultivars in 2007. F1 plants and F2 population were developed in 2009 and 2010. A promising line was selected in the F5 generation in 2011 using the pedigree method and it was evaluated for agronomic traits, yield, and soy-sprouts characteristics in a preliminary yield trial (PYT) in 2012 and an advanced yield trial (AYT) in 2013. Agronomic traits and yield were stable between 2014 and 2016 in the regional yield trial (RYT) in four regions (Suwon, Naju, Dalseong, and Jeju). Morphological characteristics of 'Aram' are as follows: determinate plant type, purple flowers, grey pubescence, yellow pods, and small, yellow, and spherical seeds (9.9 g 100-seeds-1) with a light brown hilum. The flowering date was the 5th of August and the maturity date was the 15th of October. Plant height, first pod height, number of nods, number of branches, and number of pods were 65 cm, 13 cm, 16, 4.5, and 99, respectively. In the sprout test, germination rate and sprout characteristics of 'Aram' were comparable to that of the 'Pungsannamulkong' cultivar. The yield of 'Aram' was 3.59 ton ha-1 and it was 12% higher than that of 'Pungsannamulkong' in southern area of Korea. The yield of 'Aram' in the Jeju region, which is the main region for soybean sprout production, was 20% higher than that of 'Pungsannamulkong'. The height of the first pod and the tolerance to lodging and pod shattering, which are connected to the adaptation to mechanized harvesting, were higher in 'Aram' compared to those in 'Pungsannamulkong'. Therefore, the 'Aram' cultivar is expected to be broadly cultivated because of its higher soybean sprout quality, and seed yield and better adaptation to mechanized harvesting.

'아람'은 보석(IT213209)과 Camp (IT267356)를 모본으로 2007년 인공교배 하여 F1, F2 분리집단을 전개하고 F3-F4 세대는 세계 채소 센터(AVRDC, Asian Vegetable Research and Development Center)에서 세대촉진을 수행하고 F5 세대에서 계통을 선발하였다. 2012년~2013년 생산력검정시험을 통해 수량과 농업적 형질을 평가하고, 2014~2016년 수원, 나주, 달성, 제주에서 지역적응시험을 수행하여 지역별 적응성과 재배 안정성을 평가하였다. 아람은 유한신육형이며 엽형이 삼각형, 화색이 백색, 모용색이 회색, 협색은 황색이며 종실은 소립 구형으로 백립중이 9.9 g으로 풍산나물콩보다 1.0 g 가볍고 종피색은 황색, 배꼽색은 담갈색의 질적 특성을 가지고 있다. 개화기는 8월 5일, 성숙기는 10월 15일로 만숙종이며 풍산나물콩 보다 7일 느리다. 경장은 65 cm, 착협고는 13 cm, 마디수는 16개, 분지수는 4.5개이며 분지가 길고 각도가 작은 도원추형 초형이다. 내병성 검정결과 불마름병, 종자 이병립율, 검은뿌리 썩음병, 콩나방 저항성 등이 모두 강하였으며, 콩모자이크바이러스는 G5, G6H, G7H 접종 시 모자이크 증상이 나타났으나 3년간의 자연 이병 검정결과에서는 병징이 조사되지 않았다. 발아특성은 발아세와 발아율 모두 풍산나물콩보다 우수하였으며 콩나물 특성은 풍산나물콩과 비슷한 수준이었다. 수량성은 지역적응시험 결과 남부지역 평균 3.59 ton/ha로 풍산나물콩 대비 12% 증수되었다.
