A Red Skin and Large Grain Vegetable Peanut Cultivar, ‘Sewon’

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 lengthof 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 cultivaryielded 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 accountedfor 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, stemrot, and lodging when compared with that of the reference cultivar ‘Palkwang’. In the three-year-long regional yield trials, ‘Sewon’ was moreproductive 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).
