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.

This experiments were conducted to evaluate suitable plant-type and cultivars for producing fresh pod peanut from late seeding as succeeding crop, compared with early seeding as proceeding crop or single cropping. 12 cultivars according to grain weight and plant types, 6 virginia typed cultivars(ssp. hypogaea) and 6 shinpung typed cultivars(ssp. fastigiata), were used for early and late seedings. The plant growth and yield potential in early seeding were better than those in late seeding. But the ratios of dry/fresh pod and of mature pod in late seeding were higher than those of early seeding. The yield of fresh pod by cultivars in two seeding times showed significant correlation with pod scale such as fresh pod weight, 100-grain weight, and dry seed yield positively, but pod number negatively in early seeding only. Yield of fresh peanut between Virginia and Shinpung types didn't show significant difference in early seeding, but showed in late seeding. Average yield of Virginia typed cultivars showed significantly higher than that of Shinpung typed ones. This yield gap between two plant types was the same tendency on extending seedings to July 20.

“Daeshin” (Perilla frutescens (L.) Britton), a new cultivar for leaf vegetable, was developed from a cross between YPL5 (Ipdeulkkae1/YCPL187) and Milyang2 at the National Yeongnam Agricultural Experiment Station (NYAES), RDA, in 2002. For the cultivation of leaf vegetable perilla, seeds are sown in narrow spacing of 10 x 5 cm and all branches are removed to harvest uniform leaves from main stem. Because of the narrow planting distance, it is difficult to distinguish seeds from soil in dark brown seed cultivar. Therefore the gray-white size color of “Daeshin” is very useful characteristic for easier sawing in perilla cultivation. “Daeshin” grow vigorously and yield high quality leaf. The fresh leaf yield of “Daeshin” is 9% higher than that of “Ipdeulkkae 1” (4,823 vs. 4,459 kg/10a). For the leaf production, “Daeshin” is adaptable to whole arable land in South Korea. However, the southern parts of Korea such as South Gyeongsang and South Jeolla provinces are appropriate for the seed production.

This study was conducted to improve the quantity of fatty acid in peanut oil for quality breeding program. To determine fatty acids of oleic acid and linoleic acid in F2 generation, we used near infrared reflectance spectroscopy (NIRS) with high R2 values of 0.983 and 0.991 for oleic and linoleic acids, respectively. For this experiment, two combinations with 2 mother plant( cultivar Sangpyeong and Baekseon) and 1 father plant (YGC 2) were analysed. Each cultivar Sangpyeong, Baekseon, and YGC-2 in oleic and linoleic acid have 41.6%, 58.8%, 76.9% and 44.9%, 26.2%, 5.7% respectively. Distribution of fatty acid in combination Sangpyeon/YGC-2 in oleic acid showed 38.2% to 83.5%, and in linoleic acid showed 43.2% to 6.3%. The combination of Baekseon/YGC2-2 also showed 44.6% to 81.0% in oleic acid, and 40.1% to 6.8%. This result showed the values of fatty acid in F2 generation had more wide continuous variation, compared with parents values.

Anthocyanin has antioxidant and radical-scavenging effects which may protect cells from oxidative damage and reduce risk of cardiovascular diseases and cancer. A new peanut variety “Heuksaeng”(Arachis hypogaea ssp. hypogaea L.) with dark purple peanut skin was developed at the Department of Southern Area Crop Science, NICS, in Milyang in 2014. This variety was developed from the crossing line between cultivar “Iksan 31” with short stem and erect plant type and “Iksan35” with large grain and purple skin. “Heuksaeng” which is semi erect Virginia plant type has 32cm of main stem length and 25 branch number per plant. This also show more resistant to late leaf spot, web blotch and lodging, compared with check variety “Daekwang”. Each pod has two grains with ellipse shape of purple testa and its yield components is composed of 60 mature pods of per plant, 69g of 100-seed weight, 77% of pod shelling ratio in the regional yield trials(RYT). For 3 year regional yield trials the average kernel yield of “Heuksaeng” had 4.25 MT/ha similar to that of check variety. Its seed quality show 26.9% of crude protein and 46.0% of crude oil and 53.4% of oleate in fatty acid composition. Peanut skin of variety “Heuksang” consist of 2 kind of anthocyanin compounds such as 4.67mg/100g of delpinidine-3-glucoside (D3G) and 1.18mg/100g of cyanidine-3-glucoside(C3G). Peanut variety with high anthocyanin conent in skin will be useful to the recent preference of colorful food with healthful functional compounds.

Pae, Suk-Bok,Jung, Chan-Sik,Oh, Ki-won,Ko, Jong-Chul,Kim, Jung-Tae,Park, Chung-Berm,Kwack, Yong-Ho,Kim, Soo-Dong The Korean Society of Crop Science 2002 Korean journal of crop science Vol.47 No.5

To evaluate growth habits, fresh pod yield potential, and possibility of early and late seeding, seeding dates were extended from March 21 to June 20 by PE mulching and non-mulching. Soil temperature, under 5cm from surface, above 15$^{\circ}C$ at 10 a.m. in early seeding reached about March 25 in mulching and April 5 to April 12 in non-mulching. Days to emergence and first flowering were accelerated owing to increasing temperature, as seeding was delayed. Days to emergence according to seeding dates reduced 21 to 8 day in mulching and 33 to 10 day in non-mulching. Days to flowering were ranged from 51 to 26 day in mulching and from 69 to 32 day in non-mulching and differences between mulching and non-mulching on each seeding date had 18 to 4 days. Early seedings till April 21 had 160-170 flowers per plant for 8 weeks, while late seedings from May 21 increased more speedily with 200 flower for 6 weeks. Harvesting of fresh peanut, at 80 days after first flowering, was possible from Aug. 1 to Oct. 7 (133-108 days to harvest) by mulching and from Aug. 19 to Oct. 12 (151 to 114 days) by non-mulching. Yields between mulching and non-mulching in early seeding until April 21 had more difference, but in late seeding after May 21 was higher and showed insignificance. Pod setting periods by early and late seeding were about 3 weeks equally. In late seeding pod setting were almost concentrated for front 15 days. In spite of difference of fresh pod weight between two seeding times, the distributions of average of seed weight showed nearly same tendency.
