‘채흔’은 농촌진흥청 국립식량과학원에서 개발한 기계수확에 적합하고 나물생산성이 우수한 품종이다. 2020년 직립 초형인 ‘다현’을 모본으로 협개열이 적은 ‘IT273801’을 부본으로 하여 인공교배하였고 이후 계통육종법에 따라 육성하였다. 생산력검정시험을 통해 계통명 ‘밀양3호’를 부여받아 2023년부터 2024년까지 2년동안 전국 3개 지역에서 지역적응성 시험을 수행하였다. ‘채흔’은 배축색이 녹색이고 심장형 잎, 흑색이며 만곡이 약한 꼬투리를 가진다. 녹두 파종 적기인 6월 하순에 파종할 경우 개화시와 성숙시는 각각 7월 30일, 8월 16일이고 경장은 69 cm, 경태는 6.7 mm, 분지수 1.9개, 마디수 9.9개로 조사되었다. 협장은 7.5 cm, 주당 협수는 28.5개, 협당 립수는 11.1개다. 지역적응시험 결과 평균 수량은 2.57 ton ha-1으로 ‘어울’보다 8% 높았다. 도복 정도는 ‘2’로 평가되어 ‘어울’보다 쓰러짐에 강하였고 갈색무늬병, 뿌리썩음병, 나방류, 진딧물, 노린재 등에 의한 피해는 ‘어울’과 비슷하였다. 협개열성 조사에서는 실외검정과 실내검정에서 모두 ‘어울’보다 낮은 협개열 수준을 보여 협개열 저항성이 우수하였다. 나물 특성 평가에서는 발아율이 98.3%로 높고 경실립률은 0.8%로 낮아 안정적으로 나물을 생산할 수 있는 우수한 발아특성을 보였고 배축장과 배축직경이 ‘어울’보다 증가해 생산수율이 762%로 높았다. 이상의 결과를 종합하면 ‘채흔’은 협개열 저항성에 기반한 수확 안정성과 기계수확 적응성을 갖추면서도 나물 생산성이 우수한 품종으로, 향후 국내 녹두 재배의 기계화 확대와 안정적 원료 공급에 기여할 수 있을 것으로 기대된다.

‘Chaeheun’ is a mung bean cultivar developed to improve resistance to pod shattering and suitability for mechanical harvesting, while maintaining high sprout productivity. It was derived from a cross between ‘Dahyun,’ an erect plant-type cultivar, and IT273801, a genetic resource with strong pod-shattering resistance, in 2020. Segregating generations were advanced using the pedigree method, and the selected line was evaluated in an advanced yield trial in 2022 and in regional yield trials at three locations from 2023 to 2024. When sown in late June, ‘Chaeheun’ flowered on July 30 and matured on August 16, 1 and 2 days earlier than ‘Eowool,’ respectively. Plant height was 69 cm, 16 cm shorter than that of ‘Eowool,’ indicating better suitability for mechanical harvesting. The 100-seed weight was 4.9 g, and the mean grain yield was 2.57 ton ha-1, representing an 8% increase over ‘Eowool.’ Under indoor drying conditions, the pod-shattering rate was 13.5%, confirming improved resistance to shattering. In sprout evaluation, ‘Chaeheun’ showed a germination rate of 98.3% and a hard-seed rate of 0.8%. Hypocotyl length and thickness were 8.9 cm and 2.23 mm, respectively, and sprout yield reached 762%, which was 52 percentage points higher than that of ‘Eowool.’ These results indicated that ‘Chaeheun’ is a promising cultivar for mechanized production and sprout use (Registration No. 10766).
