평안옥은 자식계통 KS140과 KS94의 교잡으로 육성된 다수성인 단교잡종이다. 2005년 생산력검정시험을 거쳐, 2006~2008년 3년 동안 4지역에서 지역적응시험을 실시한 결과 그 우수성이 인정되어 2008 농작물 직무육성 신품종선정위원회에서 신규우량품종으로 결정되었다. 이 품종의 주요특성을 요약하면 다음과 같다. 1. 평안옥의 종피색은 황색이며 입질은 반경립종이고, 출사일수는 광평옥보다 3일 늦다. 간장 및 착수고는 광평옥과 비슷하였으며, 후기녹

An indica rice cultivar, Milyang23 is a semidwarf plant type with long and slender grains, whereas a temperate japonica rice cultivar, Stejaree45 is a japonica cultivar with short and bold grains. Genetic analysis was carried out to determine the number of quantitative trait loci (QTL), chromosome location, gene action, and effects of QTLS controlling grain length, width, thickness, and shape. The grain traits averages in the recombinant inbred lines (RILs) were near the mid-parent value, but the standard deviations in the RILs were more than those of the parents. A linkage map based on 138 simple sequence repeat (SSR) markers from 12 linkage groups was constructed using the 143 RILs as the base population. The map, spanning 1208 cM of the rice genome with an average interval length of 12.9 cM, was used for QTL analysis. A total of 13 QTLS for grain quality traits were identified. The phenotypic variation accounted for by each QTL ranged from 4.2% to 10.4%, with an average of 6.7%. Among the 13 QTLS, only one QTL accounted for more than 10% of the total phenotypic variation. Each of the traits studied was governed by one or two major QTLs that accounted for the large proportion of the total phenotypic variation. Several minor QTLS explain a small proportion of the total phenotypic variance.

A new soybean cultivar for soy-paste, “Mansu”, was developed from the cross between ‘Suwon 192’, which was tolerant to disease, late maturing and high yielding, and ‘Suwon 196’ which was early maturing and large seed by soybean breeding team in the Yeongnam Agricultural Research Institute (YARI) to make new variety having large seed and high yielding. A promising line, SS97213-2B-3SSD-39-1-1, was selected and designated as the name of ‘Suwon 236’. It was characterized by regional yield trials (RYT) for three years from 2004 to 2006 and released as the name of “Mansu”. It has a determinate growth habit, purple flower, grey pubescence, pale green seed coat, yellow cotyledon, large spherical seed (26.5 grams per 100 seeds). Maturity date is 4 days later than the check cultivar, Taekwang. The average yield of Mansu was 2.93 ton per hectare in the regional yield trials (RYT) carried out for three years from 2004 to 2006 which was 7 percent higher than that of the check cultivar, Taekwang.

A new soybean cultivar for tofu and soy-paste, "Daemang 2", was developed from the cross between 'Shinpaldal 2' and'Seokryang' by soybean breeding team in the Yeongnam Agricultural Research Institute (YARI) in 2005. A promising line,SS93205-2B-8-3-2-1-1-1
