Abstract: The paper aims to breed summer soybean varieties with high quality and high yield which are suitable for planting in Huainan area, Jiangsu.‘Tongdou 11’(formerly No.08-4) was bred through generative hybridization between‘YinJ0082’(female parent) and‘Haixi13’(male parent) with pedigree method. ‘Tongdou 11’passed the regional summer soybean test in Huainan area of Jiangsu in 2013-2014 and the production test in 2015. The results showed that: in the regional summer soybean test in Huainan area of Jiangsu (2013-2014), the average yield of‘Tongdou 11’was 2928.3 kg/hm2, 7.32% higher than that of the control‘Nannong 99-6’, which was the highest yield in the regional test in the past years; in 2015, the average yield of‘Tongdou11’was 3190.5 kg/hm2 in the production test, 4.10% higher than that of the control ‘Nannong 99-6’;‘Tongdou 11’passed the Jiangsu validation in June 2016; the growth period of‘Tongdou 11’was 121 days, the plant height was 73.3 cm, the effective branch was 4.3, the pods per plant was 56.6, the grains per pod was 2.0, the 100-grain weight was 25.3 g, and its crude protein and crude fat content was 40.5% and 20.6%, respectively; the variety showed a high lodging resistance, moderate susceptible to soybean mosaic virus SC3 strain and susceptible to SC7 strain.‘Tongdou 11’is suitable for planting as summer soybean in Huainan area of Jiangsu and surrounding similar ecotopes.
