Abstract:
In order to study the genetic mechanism of resistance in development to Soybean Mosaic Virus(SMV)in soybean\[Glycine max (L.)Merr.\],a recombinant inbred line(RIL)population consisting of 144 lines derived from Zhongdou No.29 × Zhongdou No.32 was inoculated with the SMV strain SC-3.Genetic analysis was conducted by the major gene plus polygene mixed inheritance model,and QTLs were detected by composite interval mapping(CIM)based on the resistance reaction indicated by disease index.The results showed that the inheritance of resistance to strain SC-3 was controlled by two equality-additive major gene with an additive effect of -9.78 and a heritability of 97.65% for the major genes.Three QTLs were detected on chromosome 6,10 and 13 respectively,explaining 10.80%-13.41% of phenotypic variation.
