‘Heukchan’ (Arachis hypogaea L.) is a medium-sized grain and black-skin peanut variety that was developed at the Departmentof Southern Area Crop Science, National Institute of Crop Science in 2019. ‘Heukchan’ was developed from a single cross between black-skinaccession ‘Heukhwasaeng’ and Virginia-type elite line ‘HP825’. ‘Heukchan’ has short ellipse-shaped grains and a dark-purple seed coat. It alsohas a shorter main stem and branch length (39 cm and 44 cm, respectively) than those of ‘Daekwang’ (50 cm and 61 cm, respectively)which resulted in higher tolerance to lodging. On average, the number of matured pods per plant of ‘Heukchan’ was 61 and its shellingratio was 74%. The 100-seed weight of ‘Heukchan’ was 64 g which was lower than that of ‘Daekwang’ (85 g). In the regional adaptation test(from 2017 to 2019), the average grain yield of ‘Heukchan’ was 4.56 tons⋅ha-1 showing a 5% higher yield than ‘Daekwang’. The seed coat of‘Heukchan’ contains two types of anthocyanins, cyanidin 3-sophoroside and cyanidin 3-sambubioside, which are not found in ‘Daekwang’. We analyzed the chemical properties of cooked rice containing ‘Heukchan’ with an increasing substitution ratio (5, 10, 20, and 40%); mineralsand antioxidative activity as well as protein and unsaturated fatty acids were found to be significantly increased in the rice mixed with ‘Heukchan’. This new variety highlights the novel use of black-skin peanuts for mixing with rice to enhance nutrition and functionality (Registration No. 9195). KCI Citation Count: 0
