A peanut cultivar ‘Sewon’(Arachis hypogaea ssp. fastigiata L.) was developed at the Department of Southern Area Crop Science, National Institute of Crop Science (NICS) in Milyang, Korea, in 2017. The cultivar is a cross between the Shinpung-type red skin ‘Charmwon’ and the Virginia-type large grain ‘Milyang27’. ‘Sewon’, which is a Shinpung type of plant, had 13 branches per plant, main stem length of 35 cm, and branch length of 51 cm. Each pod contained two grains with red testa and a large and long ellipse-shaped kernel. The cultivar yielded 38 pods per plant, 113 g of 100-seed-weight (dry), and 1.73 seeds per pod in the regional yield trials (RYT). Crude oil accounted for 35.2% and protein 31.7% of the seed. This cultivar was resistant to early leaf spot, and it was more resistant to late leaf spot, stem rot, and lodging when compared with that of the reference cultivar ‘Palkwang’. In the three-year-long regional yield trials, ‘Sewon’ was more productive than the reference cultivar; it yielded 11.97 MT/ha of fresh pod and 5.23 MT/ha of dry grain, corresponding respectively to 21% and 16% increase compared with those of ‘Palkwang’. ‘Sewon’ is a promising high yielding peanut with early maturing and cultural stability (Registration No. 7926).

A peanut variety ‘Tamsil’ (Arachis hypogaea ssp. hypogaea L.) was developed at the Department of Southern Area Crop Science, National Institute of Crop Science (NICS), Milyang in 2016. This was developed by crossing ‘Milyang26’ with Virginia-typed short stem and ‘Milyang20’ with Virginia-typed large grain. ‘Tamsil’, which is a Virginia plant type, has 22 branches per plant, and its main stem length is 31 cm. Each pod has two grains with brown testa and long ellipse-shaped large kernel. Its yield characteristics were as follows: pods per plant, 44; 100-seed weight, 111 g; and pod shelling ratio in the regional yield trials, 78%. The seed has 48.5% crude oil and 28.8% protein content. This variety showed resistance to early leaf spot, and it is more resistant to web blotch, stem rot, and lodging than the reference variety. In the regional yield trials for 3 years, ‘Tamsil’ was more productive than the reference variety by 19% with 4.97 MT/ha grain production.
