Abstract:
149 immune or high resistant accessions , 495 susceptible accessions and 21 accessions from U .S .A were analyzedusing SSR marker Satt309 which was closely linked to rhg1 , the most important gene resistant to SCN .A total of6 alleles were identified and the allele 5th between 134bp and 149bp was new , the two accessions with allele 5th wereimmune and medium resistant to Race1 separately .The results indicated that 92 .13 % susceptible accessions had one of125bp , 134bp and 149bp alleles ;while resistant accessions distributed at each allele , but most immune or multi -resistantaccessions were identified with 128bp or 134bp allele .14 of 16 accessions with 128bp allele came from ShanxiProvince , which suggested that Shanxi Province maybe was the original of accessions with 128bp allele .Results of thepaper can be references for the identification of resistant germplasm and breeding resistant to SCN .
