Abstract

A new peanut variety "Seonan" (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was developed from the cross between the erect short stem cultivar "SP9128" and the high-yielding cultivar "Daekwang". "Seanan" which is Virginia plant type has 18 branch number per plant with early maturing and long-ellipse shaped large kernel. Each pod has two grains with brown testa and 100 seed weight was 87 g in the regional yield trials (RYT). Especially this variety has resistance to lodging owing to short stem. The free sugar and tannin content of fresh peanut are 3.7% and 0.48%, respectively, similar to check variety. In the regional yield trials "Seonan" was outyielded than check variety by 14% with 8.59 MT/ha for fresh pod and by 7% with 3.75 MT/ha for grain.

간식용 대립 땅콩의 선호도가 높음에 따라 대립 양질 다수성 신품종 육성을 위하여 직립 단경 다수성인 'SP9128'과 조숙인 '대광땅콩'를 인공교배하여 육성한 선안의 주요 특성을 요약하면 다음과 같다. 1. 선안은 버지니아 초형으로 개화기가 빠르고 지상부 생장습성은 직립 단경 다분지성이다. 2. 선안은 대광땅콩에 비해 성숙협수, 성숙협비율, 100협립수 등이 높아 양호한 등숙특성을 보이며 100립중이 87 g인 대립품종이다. 3. 도복은 매우 강한 특성을 나타내며 갈반병, 그물무늬병, 흑반병에 비교적 강하고 낙엽율도 낮아 생육후기까지 녹엽유지에 유리하였다. 4. 선안은 단백질이 28.5%, 기름함량이 50.6%이고 양질지방산중 올레산(54.3%)이 리놀산에 비해 23% 더 높아 산화안정성이 양호한 특성을 가진다. 5. 선안은 3년간 지역적응시험 결과 대광땅콩에 비하여 전국평균 8.59 ton/ha로서 14% 증수되었다.
