Abstract:: The P₁， P₂， F₁， F₂ and 184 RILs of Kefeng No. 1×Nannong1138-2 were inoculated with the SMV strain group SC-13 to evaluate their resistance. The results showed that Kefeng No.1 and F₁ were resistant to SC-13， Nannong 1138-2 was susceptible. F₂ segregated in a 3∶1 ratio and the RILs in a 1∶1 ratio， which indicated a dominant gene controlled the resistance to SC-13. Through linkage analysis， the resistance gene Rsc-13was mapped on the linkage group N8-D1b+W and linked with Rn1、Rn3、Rsc-7.
