돌연변이 육종에 의한 재래종 서리태 개량 신품종 콩 "조생서리"
송희섭,김진백,이경준,김동섭,김상훈,이상재,강시용 한국육종학회 2010 한국육종학회지 Vol.42 No.3
재래종 서리태는 밥밑용 콩으로 한국인에게 선호되고 있으나, 숙기가 느려 수량성이 떨어지고 콩알이 커서 청소년들에게는 기피 경향이 있다. 서리태의 특성을 개량하고자 1994년 수집한 서리태 종자에 감마선 250 Gy를 조사하여 돌연변이 육종을 시도하였다. 그 후대에서 숙기가 빠르고 수량성이 높으며 콩알 크기가 작아진 유망 돌연변이 계통을 선발하여 ‘조생서리’로 명명하고, 2005년도에 품종보호권 및 국가품종목록등재 신청을 하였으며, 2008년도에 등록을 ‘Seoritae’ is a very famous variety of black soybean for mixed cooking with rice in Korea. However, it has a couple of bad traits such as late flowering and maturity. To improve these characteristics, seeds of original ‘Seoritae’ were irradiated using a 250 Gy gamma ray in 1994. Some mutants were identified and finally a new soybean variety ‘Josaengseori’ was developed in 2005. This variety has a few distinguishable characteristics such as smaller grain size, early maturity and high yielding compared to the ‘Seoritae’. The flowering period of ‘Josaengseori’ is 57 days after seeding (DAS), which is 10 days earlier than that of ‘Seoritae’ (67 DAS). The maturation period of ‘Josaengseori’ is 130 DAS, which is 34 days earlier than ‘Seoritae’ (164 DAS). And the total yield of the new variety with 179 kg/10a is 2.4 times higher than that of ‘Seoritae’ with 74 kg/10a. 100 grain weight of ‘Josaengseori’ is 32.8 g, which is 20% lower than that of ‘Seoritae’ with 40.1 g.

宋禧燮,金鳳龍,權臣漢 韓國作物學會 1988 Korean journal of crop science Vol.33 No.4
The present study was conducted to evaluate agronomic characters of the soybean germplasm which was collected from the sites covering whole areas of southern Korean peninsula. A total of 2,748 Korean native soybeans was grouped for fruiting period and in this group frequency distribution of the important agronomic characters and relationships among the characters were determined. The results obtained were summarized as follows; The soybean germplasm was comprised of Seoul·Kyonggi-do 7.5%, Kangwon-do 13.3%, Chungchongbuk-6.6%. Chungchongnam-do 12.3%, Chollabuk-do 10.7%, Chollanam-do 12.6%, Kyongsangbuk-do 20.8%, Kyongsangnam-do 15.3% and Cheju-do 0.6% in number of collections. Frequency distribution of the germplasm for fruiting period was 0.14% in Group I (below 55 days). 1.67% in Group II (56-60 days), 10.58% in (Group III(61-65 days), 23.18% in Group IV(66-70 days), 25.91% in Group V(71-75 days) 19.79% in Group Ⅵ(76-80 days), 15.1% in Group Ⅶ(81-85 days) and 3.6% in Group Ⅷ(over 85 days). The lines over 70 days in fruiting period were as much as 64.4% of germplasm. The fruiting period varied largely from 45 days to 91 days. Fruiting period was positively correlated to seed weight, days to maturity, days to flowering, plant height and number of branches per plant, respectively. While. it was negatively correlated to number of pods, lodging and virus infectivity, repectively, and in particular negative correlation was shown significantly between yield and fruiting period. Average yield was very high as much a 1.389kg/ha in fruiting period Group I, and decreased with increment of fruiting period, 1.400kg/ha in Group II. 1.384kg/ha in Group III. 1,299kg/ha in Group IV, 1,197kg/ha in Group V, 1,117kg/ha in Group Ⅵ, 967kg/ha in Group Ⅶ and 832kg/ha in Group Ⅷ.

Genetic variations among the Korean soybean germplasm were surveyed using several molelcuar markers. In the studies of 38 different soybean genotypes including 18 Glycine max and 20 Glycine soja, the overall genetic variation among the wild soybean was greater and wider than that of cultivating soybeans. In the cluster analysis, wild germplasm was separated from cultivating soybeans at 83% similarity level. Morphologically intermediate typed soybeans, Glycine gracilis, between wild soybeans and cultivating soybeans were also clustered between these two ecotype soybeans. Genetic diversity and differentiation among the 57 wild soybean accessions collected from riversides of five major rivers showed significantly higher generic diversity and differentiation than those of cultivated soybeans by SSR (simple sequence repeat) variation. There was no specific SSR alleles to the populations from any riversides, which might indicate the present genetic variation among the wild soybeans could predate the dispersal of wild soybeans along the rivers. While the wild soybeans from Nakdong river showed highest level of genetic diversity, the soybeans from Sumjin river showed the highest genetic differentiation value in the comparison of genetic diversities among the populations from each riverside.
