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.

A new peanut variety ‘K-Ol’(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 a cross between ‘Baekseon’ with Shinpung type and ‘F435-5’ with high oleic acid. ‘K-Ol’ is the first high oleate variety in Korean and has short stem and Shinpung plant type. It has 10 branches per plant and its length of main stem was 43 cm. Each pod has two grains with brown testa and short ellipse-shaped kernel. Its yield components showed 46 pods per plant, 74 g of 100-seed-weight and 76% of pod shelling ratio in the regional yield trials (RYT). Seed contains 26.0% protein and 50.7% crude oil with a typical fatty acid composition of 82.9% oleate and 2.7% linoleate. This variety showed more resistant to late leaf spot, web blotch, stem rot and lodging, compared to reference variety ‘Daekwang’. In the regional yield trials for 2 years ‘K-Ol’ showed 4.34 MT/ha for grain yield by 99% of production level of reference variety.

Each pod has two grains with brown testa and long ellipse-shaped large kernel. Its yield components showed 45 pods per plant, 84 g of 100-seed-weight and 79% of pod shelling ratio in the regional yield trials (RYT). Seed quality showed 47.3% of crude oil and 27.6% of protein content. This variety showed resistant to early leaf spot and had more resistant to stem rot and lodging, compared to reference variety. In the regional yield trials for 3 years ‘Huaseon’ was more productive than reference variety by 12% with 4.78 MT/ha for grain production.

A new peanut(Arachis hypogaea ssp. fastigiata L.) variety “Hwaseon(Milyang50)” with the high yield potential was developed at the Department of Functional Crop, NICS, in Milyang in 2013. This was developed from the crossing line between cultivar “Iksan 31” with large grain and high quality and “SP9614” with short stem. “Hwaseon” which is Shinpung plant type has 41cm of main stem length and 10 branch number per plant. Each pod has two grains with long ellipse shape of brown testa and yield components is composed of 45 mature pods of per plant, 84g of 100-seed weight, 79% of pod shelling ratio in the regional yield trials(RYT). Seed quality showed 47.3% of crude oil and 27.6% of protein content. This variety also showed more resistant to early leaf spot, and stem rot, compared with check variety “Daekwang”. In the regional yield trials “Hwaseon” outyielded check variety by 12% with 4.78 MT/ha for kernel.

High oleate oil enhance flavors and shelf life and decrease coronary heart disease mortality. A new peanut(Arachis hypogaea ssp. fastigiata L.) variety “K-Ol(Milyang56)” with high oleic acid of fatty acid composition was developed at the Department of Functional Crop, NICS, in Milyang in 2013. This variety was developed from the crossing line between cultivar “Baekseon” with large grain and erect plant type and “F435-5” with high oleate and runner type. “K-Ol” which is Shinpung plant type has 43cm of main stem length and 10 branch number per plant. This also show more resistant to late leaf spot, web blotch and stem rot, compared with check variety “Daekwang”. Each pod has two grains with short ellipse shape of brown testa and yield components is composed of 46 mature pods of per plant, 74g of 100-seed weight, 76% of pod shelling ratio in the regional yield trials(RYT). For 3 year regional yield trials the average yield of “K-Ol” had 4.45 MT/ha for kernel similar to that of check variety. Seed quality show 50.7% of crude oil and 82.9% of oleic acid. The oil acidification of “K-Ol” measured by acid value(P-A value) variation for 3 hours at 180 ℃ showed one-ninth as low as ‘Daekwang’ do. This variety is expected to develop new demand area such as the improvement of cardiovascular disorders and shelf-life, and import substitution of olive oil.

A new peanut(Arachis hypogaea ssp. fastigiata L.) variety “Danwon(Milyang51)” with short stem length and lodging resistance was developed at the Department of Functional Crop, NICS, in Miryang in 2013.

This is more resistant to early and late leaf spot, web blotch and stem rot, compared with check variety “Daekwang”. In the regional yield trials “Danwon” outyielded check variety by 6% with 4.52 MT/ha for kernel.

본 연구는 땅콩 파종후 발아기의 내습성 기초자료를 얻고자 파종일수와 침수처리에 따른 출현율을 조사하고 적정 내 습성 검정방법을 찾고자 하였으며 이를 이용하여 품종별 내 습성 차이를 구명해보고자 본시험을 수행하였다. 종자의 흡수율 50%에 도달한 것은 공히 5시간 정도 소요 되었으며 24시간 후에는 조광 66.6%, 대광 65.1%, 팔광 67.1%에 도달하여 품종간 큰 차가 없었다. 땅콩종자를 vermiculite 풋트에 파종한 후 바로 침수시켰을 때 대광땅콩 과 팔광땅콩은 공히 침수 16일까지도 90% 정도의 출현율 을 유지하였고 그 후로는 급속히 감소하여 침수 25일에는 출현율이 거의 없었다. 파종 후 발아일자 1~4일에 각각 침 수일자 1~5일간 침수처리를 하였을 때 발아일수가 길어질 수록, 침수일자가 길어질 수록 땅콩의 출현율이 급속히 떨 어졌다. 대광땅콩은 파종 1~3일 후 2일 침수처리까지, 팔광 땅콩은 파종 1~2일 후 2일 침수처리까지 정상 출현하였으 며 두 품종 공히 3일 이상 침수에서는 모든 발아일수(1~4 일)에서 출현율이 급속히 떨어지고 있었다. 파종 2일 후 3일간 침수처리 방법에 따라 국내육성 31품 종에 대해 침수 시 내습저항성을 검정한 하였을 때 출현율 은 0에서 69%까지 분포하였고 대광땅콩 가장 높았다.
