영문 초록

‘Hae-Ol’ (Arachis hypogaea ssp. Hypogaea) -a high-oleate peanut variety-was developed at the Department of Southern Area Crop Science,National Institute of Crop Science in 2018. This variety was selected from the pedigree line crossed between short stem Virginia-type ‘HP825’and high-oleate elite line ‘YG316’. The crude fat content of ‘Hae-Ol’ was 50.8%, and its oleic acid composition was 83.0% showing high-oleateproperty compared to that of ‘Daekwang’ variety (57.3%). The ratio of oleic acid to linoleic acid, which represents the oxidative stability, was12 times higher in ‘Hae-Ol’ than in ‘Daekwang’. The increments in acid value and peroxide value were relatively slower in ‘Hae-Ol’, under thecondition of accelerated oxidation. Over the three years of regional adaptation test (2016-2018) conducted at four regions, ‘Hae-Ol’ showed significantlyhigher grain yield (4.88 MT⋅ha-1), which was 16% more improved than that of ‘Daekwang’ (4.20 MT⋅ha-1). The seed of ‘Hae-Ol’ is brownin color and long-ellipse in shape and its 100-seed weight was 96 g. On field, ‘Hae-Ol’ demonstrated more resistance to late leaf spot (Cercosporidiumpersonatum) and web blotch (Phoma arachidicola). It also had a shorter branch and main stem, which was related to the higher tolerance to lodgingstress. The release of ‘Hae-Ol’ could contribute to the production of peanuts with enhanced quality and higher yield, and it is expected to be notablybeneficial to both the producers and manufacturers (Registration No. 8407).
