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.
A new peanut variety ‘Sangan’ (Arachis hypogaea ssp. fastigiata L.) was bred at the Department of Functional Crop, National Institute of Crop Science (NICS), in Milyang 2011. This was developed from the cross between high quality cultivar ‘Palkwang’ and fewer branched germplasm ‘Chinese collect. 1’. ‘Sangan’ which is Shinpung plant type had 10 branches per plant and its length of main stem was 43 cm. Each pod has two grains with brown testa and long ellipse-shaped large kernel, and 100 seed weight was 96 g in the regional yield trials (RYT). Seed quality showed 48.5% of crude oil and 29.1% of protein content. This variety also showed more resistant to late leaf spot and web blotch, compared with reference cultivar. In the regional yield trials ‘Sangan’ was more productive than reference cultivar by 15% with 4.87 MT/ha for grain production.
