콩 품종육성에 있어 잎의 크기가 종실무게와 관련된 형질 의 초기 분리세대에서 조기선발 지표로서 활용 가능성을 구 명하고자 재래종, 도입종 및 야생종 등 229개 품종 및 유전 자원을 대상으로 단엽과 제1본엽 및 제3본엽과 종실 무게 와의 상관관계를 조사 분석한 결과를 요약하면 다음과 같다. 1. 시험재료 229개 품종 및 유전자원의 단엽 면적은 3.2 ∼33.8 cm2, 제1본엽 면적은 9.2∼29.5 cm2, 제3본엽 면적은 7.2∼58.9 cm2, 종실의 100립 무게는 2.7∼ 39.0 g의 범위를 나타내었다. 2. 엽 면적과 종실 무게간에는 높은 정의 상관이 있었고, 상관의 크기는 단엽(r=0.80**), 제1본엽(0.75**), 제3 본엽(0.67**) 순으로 나타났다. 3. 엽의 장폭과 종실무게 사이에는 유의한 정의 상관이 있었고 단엽의 길이(0.71)와 폭(0.79)이 제1본엽, 제3 본엽 보다 상관이 높았으며, 엽장보다는 엽폭이 높은 상관을 보였다. 조사된 콩 잎의 장 · 폭비는 상위엽이 높았다. 4. 콩 종실크기와 관련된 생육 초기선발의 간접지표로서 단엽 크기와 단엽의 폭을 이용하는 것이 제일 유리할 것으로 판단되었다.

The development of random amplified polymorphic DNA (RAPD) and expressed sequence tag-derivedsimple sequence repeats (EST-SSRs) provided a useful tool for investigating Korean ginseng genetic diversity. In this study,18 polymorphic markers (7 RAPD and 11 EST-SSR) selected to assess the genetic diversity in 31 ginseng accessions (11Korean ginseng cultivars and 20 breeding lines). In RAPD analysis, a total of 53 unique polymorphic bands were obtainedfrom ginseng accessions and number of amplicons ranged from 4 to 11 with a mean of 7.5 bands. Pair-wise genetic similaritycoefficient (Nei) among all pairs of ginseng accessions varied from 0.01 to 0.32, with a mean of 0.11. On the basis of theresulting data, the 31 ginseng accessions were grouped into six clusters. As a result of EST-SSR analysis, 11 EST-SSR mark-ers detected polymorphisms among the 31 ginseng accessions and revealed 49 alleles with a mean of 4.45 alleles per primer.The polymorphism information content (PIC) value ranged from 0.06 to 0.31, with an average of 0.198. The 31 ginsengaccessions were classified into five groups by cluster analysis based on Nei’s genetic distances. Consequently, the results ofginseng-specific RAPD and EST-SSR markers may prove useful for the evaluation of genetic diversity and discrimination ofKorean ginseng cultivars and breeding lines.

It has determinate growth habit, white flower, green pod color, oval shape of crossed section of pod at the harvesting time for edible pod, white seed coat and middle seed size (21.1 grams per 100 seeds). The average yield of edible pod of “Noghyeob 1” was 24.25 M/T per hectare in the yield trials which were carried out at the green house in spring and autumn in 2005. It was 7 percent higher than that of the check cultivar “Kangnangkong 1”.

A new garden pea cultivar, Daehyup 2, was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. It was selected from the cross between Olwandu and Sachulwandu in 1996. The preliminary, advanced, and regional yield trials for evaluation and selection of this cultivar were carried out from 2003 to 2006.

A new black seed coat soybean variety, “Socheong” was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. The goal to breed the black seed coat soybean is to develop the cultivar with high yield, lodging tolerance, resistant to disease such as soybean mosaic virus (SMV), and bacterial pustule and seed size. Socheong was selected from the cross between Milyang 78, which was late maturing, susceptible to lodging and SMV and with large seed size and green cotyledon, and Peking which was tolerant to lodging and with small seed size. The preliminary, advanced and regional yield trials for evaluation and selection of this variety were carried out from 2002 to 2006. It has determinate growth habit, white flower, brown pubescence, brown pod color, black seed coat, green cotyledon, elongated flattened seed shape, oval leaf shape and small seed size (15.7 grams per 100 seeds), and it was 3 days later in maturity than the check cultivar Cheongjakong. Socheong was higher, in the seed quality of sucrose and total sugar contents (6.8 and 8.2%) and isoflavone contents (1,754 ㎍/g) than the check cultivar. Futhermore, it has good characteristics for mechanical harvest, such as lodging tolerance, pod shattering and stem diameter. It also has been identified to have resistance to soybean mosaic virus symptom which was the troublesome soybean diseases. The average yield of Socheong was 2.21 ton per hectare in the regional yield trials carried out in four locations of Korea among seven locations from 2004 to 2006, which was 5 percent lower than the check cultivar Cheongjakong.

A new black seed coat soybean cultivar, “Heugmi” was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. The goal to breed the black seed coat soybean is to develop the cultivar with high yield, lodging tolerance, resistant to disease such as soybean mosaic virus (SMV), and bacterial pustule and seed size. Heugmi was selected from the cross between Milyang 78, which was late maturing, susceptible to lodging and SMV and with large seed size and green cotyledon, and Milyang 68, which was middle maturing, resistant to lodging and SMV and with middle seed size and yellow cotyledon. The preliminary, advanced and regional yield trials for evaluation and selection of this cultivar were carried out from 2001 to 2006. It has determinate growth habit, purple flower, brown pubescence, black pod color, black seed coat, green cotyledon, spherical seed shape, oval leaf shape and middle seed size (24.8 grams per 100 seeds), and it was 2 days earlier in maturity than the check cultivar Cheongjakong. Heugmi was better in the seed quality of crude protein contents, sucrose and total sugar contents than the check cultivar. It also has been identified to have resistance to SMV which was the troublesome soybean diseases. The average yield of Heugmi was 2.53 ton per hectare in the regional yield trials carried out in seven locations of Korea from 2004 to 2006, which was 8 percent higher than the check cultivar Cheongjakong.
