Peanut is grown worldwide in the tropics and temperate zones primarily as an oilseed crop (38-54%) and protein source(25-30%). A new peanut variety “Daan”(Arachis hypogaea ssp. fastigiata L.) with the high yield potential was developed at the Department of Southern Area Crop Science, NICS, in Milyang in 2014. This was developed from the crossing line between cultivar “Sangpyeong” with short stem and high quality and “Dakwang” with large grain. “Daan” which is Shinpung plant type has 44cm of main stem length and 13 branch number per plant. Each pod has two grains with long ellipse shape of brown testa and yield components is composed of 34 mature pods of per plant, 127g of 100-seed weight, 75% of pod shelling ratio in the regional yield trials(RYT). Seed quality showed 47.8% of crude oil and 28.3% of protein content. This variety also showed more resistant to early leaf spot, late leaf spot, web blotch, stem rot and lodging compared with check variety “Daekwang”.
In the regional yield trials “Daan” outyielded check variety by 16% with 5.00 MT/ha for kernel yield.
“Jojoong”, a winter wheat(Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA. It was derived from the cross “Suwon272/Olgeuru//Keumkang/Suwon252” during 2002. “Jojoong” was evaluated as “Iksan360” in advance yield trial test in 2011. It was tested in the regional yield trial test between 2012 and 2014. “Jojoong” is an awned, semi-dwarf and hard winter wheat, similar to “Keumkang” (check cultivar). The heading and maturing date of “Jojoong” were earlier to “Keumkang”. “Jojoong” had lower test weight (799 g/L) and 1,000-grain weigh (35.6g) than “Keumkang” (816 g/L and 45.5g, respectively). “Jojoong” showed resistance to winter hardiness and pre-harvest sprouting, which lower withering rate on the high ridge (10.5%) and rate of pre-harvest sprouting (10.5%) than “Keumkang” (31.7 and 21.4%, respectively). “Jojoong” showed similar protein content (12.5%), SDS-sedimentation volume (43.5ml) and gluten content (8.6%) to “Keumkang” (12.9%, 58.5ml and 8.5%, respectively). It showed higher lightness (93.17) in flour color than “Keumkang” (91.95, respectively). “Jojoong” showed higher lightness (81.50) of noodle dough sheet than “Keumkang” (80.95). “Jojoong” exhibited similar hardness (3.84N) and higher springiness and cohesiveness of cooked noodles (0.94 and 0.66) compared to “Keumkang” (3.88N, 0.90, and 0.62, respectively). Average yield of “Jojoong” in the regional adaptation yield trial test was 5.09 MT/ha in upland and 5.35 MT/ha in paddy field, which was 9% and 8% higher than those of “Keumkang” (4.67 MT/ha and 4.92 MT/ha, respectively).
A new lettuce cultivar ‘Misun’ (Lactuca sativa L.) with wrinkled traverse narrow elliptic and deep red leaf, which has late bolting and high yield. It was developed from a cross between ‘Yeoreum Jeocgchima’ (deep red leaf color) and ‘Yeoreumdukseomjeokchukmyeon’ (high yield). The cross and selection for advanced lines had been done by the pedigree method from 2001 to 2008. The advanced lines were evaluated for yield and adaptability at several locations in Korea (Gangwon-do, Gyeonggi-do, Chungcheongbuk-do, Jeollabuk-do, Gyeongnam-do, and Jeju-do) from 2009 to 2011 year. The ‘Misun’ has gray seed color and traverse narrow elliptic leaves. The shelf-life of ‘Misun’ was four weeks longer than ‘Dukseomjeokchukmyeon’at 4℃. The anthocyanin content of ‘Misun’ (88.32 mg/100 g) was higher than that of ‘Dukseomjeokchukmyeon’(74.78 mg/100g). The BSL (latucin+8-deoxylactucin+lactucopicrin) content of ‘Misun’ (5.0 ug/g, DW) is lower than that of ‘Dukseomjeokchukmyeon’(12.0 ug/g, DW). Compared to ‘Dukseomjeokchukmyeon’, marketable yield of ‘Misun’(289 g per plant) was 11% higher than that of it, showed good yield in fall season cultivation and has particularly improved expression of red leaf color at high temperature cultivation in the field. Furthermore, its taste is better, more crispy, and sweeter than those of ‘Dukseomjeokchukmyeon’. Thus, this new cultivar ‘Misun’ can be suitable for cultivation in low temperature during spring and fall season season.

This experiment was conducted to develop new black sesame variety with multi-disease resistance and high yield potential. A new sesame variety ‘Daheuk’ was developed from Yeongnam Agricultural Research Institute in 2009. Cross was made by ‘Whahuck’ with high disease resistance and F1 line of ‘Yoosung’ and ‘Keunhuck’ with high yields capacity & disease resistance, followed by pedigree selection, yield test and RYT by the sesame breeding team at the National Institute of Crop Science and Yeongnam Agricultural Research Institute up to 2009. The variety showed higher disease resistance and yield potential rather than that of check variety ‘Yangheuk’. Average stem length and the number of capsules per plant were 117cm, 75 respectively. It’s 1000 grains weight was about 2.80g indicating 0.20g higher than that of ‘Yangheuk’, and it’s protein content was about 25.7% which is higher than that of check variety. ‘Daheuk’ also contained total 3.0mg/g of lignan compounds which is lower than that of ‘Yangheuk’.
