A new peanut variety ‘Heuksaeng’(Arachis hypogaea ssp. hypogaea L.) was developed at the Department of Southern Area Crop Science, National Institute of Crop Science (NICS) in 2014. This was developed from the cross between ‘Iksan 31’ with Virginia typed short stem and ‘Iksan 35’ with large grain. ‘Heuksaeng’ is the first purple testa variety developed in Korean. It has 25 branches per plant and its length of main stem was 32 cm. Each pod has two grains with puple testa and long ellipse-shaped kernel. Its yield components showed 60 pods per plant, 69 g of 100-seed-weight and 77% of pod shelling ratio in the regional yield trials (RYT). Seed quality showed 46.0% of crude oil and 26.9% of protein content. This variety has anthocyanins typed as delpinidin-3-glucoside (D3G) and cyanidin-3-glucoside (C3G) in seed testa. This variety showed more resistant to late leaf spot, web blotch, and lodging, compared to reference variety. In the regional yield trials for 2 years, ‘Heuksaeng’ with 4.25 MT/ha for grain production has the same productivity to reference variety.
