A new peanut variety 'Danwon'(Arachis hypogaea ssp. fastigiata L.) was developed at the Department of Southern Area Crop Science, National Institute of Crop Science (NICS) in Milyang 2013. This was developed from the cross between 'YG75' with Shinpung type and 'SP9617' with larger grain. 'Danwon' is the first Shinpung typed short stem variety ever developed in Korea. It has 13 branches per plant and its length of main stem was 32 cm. Each pod has two grains with brown testa and long ellipse-shaped large kernel. Its yield components showed 40 pods per plant, 91 g of 100-seed-weight and 77% of pod shelling ratio in the regional yield trials (RYT). Seed quality showed 48.7% of crude oil and 26.9% of protein content. This variety showed more resistant to early and late leaf spot, web blotch, stem rot and lodging, compared to reference variety. In the regional yield trials for 3 years 'Danwon' was more productive than reference variety by 6% with 4.52 MT/ha for grain production.
