This experiment was conducted to select cultivar suitable for peanut sprout from general Korean peanut cultivars developed already. On sprouting peanut, it rapidly increase the content of trans-resveratrol that has effects on anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular in mouse. For this experiment we tested peanut sprout characteristics on 37 cultivars cultivated for 7 days at 26℃ temperature. The characteristics among cultivars showed the variations as follow: The range of 100 grain weight is 56 to 142, hypocotyl length 4.3 cm to 5.8 cm, diameter of hypocotyl 5.0 to 8.0 mm, epicotyl 0.8 cm to 4.6 cm, seedling ratio per seed number 84 % to 100 %, weight per seedling 4.9 g to 8.4 g, the rate of hypocotyl cleavage 0 % to 46 %, the content of trans-resveratrol 22.5 ㎍/g to 88.2 ㎍/g and sprout yield 360 % to 820%. We considered the selecting points as high sprout yield, high seedling rate, high resveratrol content, high low brownish cotyledon, no hypocotyl cleavage, and fat hypocotyl etc. Fortunately, the best cultivar "Jokwang" was selected on these conditions with 7.8 mm diameter, clean cotyledon color, 100 % seedling rate, 0 % hypocotyl cleavage, 63.3 ㎍/g resveratrol, and 820 % sprouting yield. This cultivar may use as new food and nutraceutical material.

A new vegetable peanut cultivar “Baekan” (Arachis hypogaea ssp. fastigiata. L.) was developed at the Yeongnam Agri-“Suwon95” and the high-yielding cultivar “Suwon91”. “Baekan” with a Shinpung plant type has less branch number with earlyflowering and long ellipse-shaped large kernel. Each pod with very shallow constriction had two grains with brown testa and 100seed weight was 101 g in the regional yield trials (RYT). This cultivar also showed higher free sugar and protein contents in seed,and was more resistant to the early and late leaf spots and web blotch compared with the check one. In the regional yield trials,

A new peanut cultivar “Sangpyeong” (Arachis hypogaea ssp. hypogaea L.)was developed at the Yeongnam Agricul-and the very short stem cultivar “Satonoca”. “Sangpyeong” with Virginia plant type has more branch number with early floweringand ellipse-shaped large kernel, compared with the check cultivar. Each pod has two grains with brown testa and 100 seed weightwas 89g in the regional yield trials (RYT). This cultivar also showed more resistance to early and late leaf spots and web blotchcompared with the check one. Especially it has resistance to lodging owing to short stem. In the regional yield trials, “Sang-

A new peanut variety “Baekseon” (Arachis hypogaea ssp. fastigiata L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2004. It was developed from the cross between the disease resistant cultivar “Suwon95” and the early maturing cultivar “Suwon94". “Beakseon” which has Shinpung plant type is less branch number with early flowering and long ellipse-shaped large kernel. Each pod which showed very shallow constriction had two grains with light brown testa and 100 seed weight was 96 g in the regional yield trials(RYT). This variety also contained higher free sugar and protein contents in seed quality, and had more resistant to early and late leaf spots and web blotch compared with check one. In the regional yield trials “Baekseon” was outyielded than check variety by 16% with 8.64 MT/ha for fresh pod and by 12% with 3.66 MT/ha for grain. It was evaluated to be suitable for vegetable peanut by its fresh pod yield and related characteristics.

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.
Effects of Plant Types and Cultivars on Pod Yield in Late Seeding Peanut
Pae, Suk-Bok,Kim, Jung-Tae,Shim, Kang-Bo,Hwang, Chung-Dong,Chung, Chan-Sik,Lee, Myung-Hee,Park, Keum-Yong The Korean Society of Crop Science 2007 Korean journal of crop science Vol.52 No.1
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.
