간식용 대립 땅콩의 선호도가 높음에 따라 대립 양질 다수성 신품종 육성을 위하여 단경 대립인 ‘Satonoka’와 소분지내병 단경인 ‘밀양16호’를 인공교배하여 육성한 ‘아미’의 주요 특성을 요약하면 다음과 같다. ‘아미’는 신풍 초형으로 개화기가 빠르고 지상부 생장습성은 직립 소분지성이다. ‘아미’ 는 ‘팔광’ 땅콩에 비해 주당협수, 성숙협비율, 협당립수 등이높으며 100립중이 84 g인 대립품종이며, 도복은 비교적 강한특성을 나타내며 그물무늬병, 흑반병은 비슷한 정도이다. ‘아미’는 단백질이 26.2%, 기름함량이 50.5%이고 양질지방산중올레산(60.5%)이 리놀산(23.6%) 보다 훨씬 더 높아 기름의산화안정성이 양호한 특성을 가진다. ‘아미’는 3년간 지역적응시험 결과 풋땅콩 수량이 전국평균 10.10 ton/ha로서 ‘팔광’ 땅콩에 비하여 9% 증수되었다. ‘아미’는 대립종이므로 적기에 파종하고, 충분한 성숙을 위하여 성숙기 병해 방제에 유의해야 하며 강원도와 산간 고냉지를 제외한 지역에서 적응성이 높은 품종이다(품종등록 번호: 제5260호).
Abstract
A new peanut variety ‘Ami’ (Arachis hypogaea ssp. fastigiata.) was bred at the Department of Functional Crop, NICS, in Milyang in 2012. This was developed by pedigree method after the cross between the short stem cultivar ‘Satonoka’ and the disease resistant cultivar ‘Milyang16’. ‘Ami’ which is Shinpung plant type had 10 branches per plant and its length of main stem was 50 cm. Each pod has two grains with brown testa and long ellipse-shaped large kernel, and its 100 seed weight was 84 g in the regional yield trials (RYT). ‘Ami’ showed 50.5% of crude oil and 60.5% of oleic acid composition in dry seed, and had 24.9 mg/g of sucrose and 4.5 mg/g of tannin content in fresh peanut. In the regional yield trials, ‘Ami’ was more productive than reference variety by 7% with 10.10 MT/ha for fresh pod production and by 14% with 4.51 MT/ha for dry grain production.
