’ Tongdou 10 ’（ formerly No. 06-299） was bred through generative hybridization between’99015’（ female parent） and ’ Yin 99-04’（male parent） with pedigree method, selected stable agronomic character and quality and resistance for successive years, passed the regional summer soybean test of Jiangsu Huainan area between 2010—2012 and production test in 2013,through the Jiangsu Province validation in June2014. In the regional summer soybean test of Jiangsu Huainan area between 2010—2012,the average yield of’ Tongdou 10 ’ was 2 775. 3 kg/hm^2,3. 54% higher than that of the control ’ Nannong 99-6 ’,which was the highest yield in the regional test in the past years. In 2013, the average yield of ’ Tongdou 10 ’ was 2 861.9 kg/hm^2 in the production test,increasing 7.45% over that of the control conducted in Huainan summer soybean area of Jiangsu Province, compared with the control ’ Nannong 99-6 ’. The growth period of ’ Tongdou 10’ was 112 d, the plant height was 78.2 cm,the effective branch was 4. 6,the pods per plant was 50.6,the per pod was 1.90,the100-grain weight was 22.4 g. Its crude protein and crude fat content was 41.63% and 19. 56% respectively. The variety showed a high lodging resistance and a moderate resistance to soybean mosaic virus SC-3 strain and moderate susceptible to SC-7 strain,and it was suitable for planting in Jiangsu Huainan area and surrounding similar ecotopes.
