摘要：

Rhizomania, caused by Beet necrotic yellow vein virus (BNYVV), is an important sugar-beet disease worldwide. The aim of this study was to investigate and map BNYVV resistance from the WB258 source. Presence of a major resistance gene (termed Rz5) was indicated by similar to 1 : 1 segregation of virus levels in a population of 170 individuals derived from WB258. The maximum logarithm of odds (LOD) position for Rz5, identified by interval mapping, explained similar to 81% of the phenotypic variance. Rz5 was mapped alongside the previously identified Rz4 from the R36 source. Rz4 and Rz5 were located to 6.9 cM and 6.0 cM regions, respectively, on chromosome III by interval mapping. These locations corresponded well to the position of the widely deployed Rz1 gene, suggesting that the three genes could represent an allelic series. Physical mapping is probably required to confirm this however. BNYVV resistance genes from novel sources are potentially important in breeding for more durable resistance either as separate genes or as BNYVV race-specific alleles.
