- Abstract:
- ?Soybean Mosaic Virus(SMV)and soybean cyst nematode(SCN)are the two most important diseases causing soybean yield loss and seed quality deterioration.A total of 122 soybean cultivars,which were from the national soybean regional trials of China during 20102012,were evaluated for resistance to SMV and SCN at seedling stage in a net room with ahidfree inoculated with 4 prevalent SMV strains,SC3,SC7 and SC15,SC18 and SCN Race 1.The results showed that 32，34 and 22 soybean cultivars were resistant to SC3,SC7 and both,accounting for 32%, 34% and 22% of the soybean cultivars inoculated with the corresponding strain(s),respectively;3,3 and 2 soybean cultivars were resistant to SC15,SC18 and both,accounting for 13.6%,13.6% and 9.09% of the soybean cultivars inoculated with the corresponding strain(s),respectively.The results of identification of resistance for SMV from 2003 to 2012 showed that some progress of soybean breeding for SMV resistance had been made,the ratio of moderate resistant soybean cultivars increased while susceptible cultivars decreased significantly.The results of identification for SCN resistance of 51 soybean cultivars from HuangHuaiHai valleys showed that only one soybean cv. Cangdou 1 was high resistant,34 were high susceptible cultivars,accounting for 1.96% and 66.67% of the total,respectively,and the other were moderate resistance and susceptible cultivars.The ten years’ results of identification of resistance for SCN showed that little progress of soybean breeding for SCN resistance had been made.Soybean cv. Lu 98011-14,Cangdou 11,Kaidou 41 and Lu 97013-1,were resistant to both SMV and SCN.
