| Abstract:
Plum pox virus (PPV) causes serious damage in apricots and breeding and growing of PPV-resistant apricot cultivars are the only way of its efficient control. An integrated genetic linkage map for apricot (Prunus armeniaca L.) was obtained using a BC1 progeny ‘LE-3246’ × ‘Vestar’. A total of 316 molecular markers (290 AFLPs, 26 SSRs) and the resistance to PPV were assigned to 8 linkage groups covering 574 cM of the apricot genome. The average distance between adjacent loci is 2.5 cM. A PPVres1 locus conditioning resistance to PPV was mapped in linkage group 1. Several AFLPs and an SSR tightly linked to PPVres1 locus were identified. The construction of a genetic map for apricot and identification of molecular markers linked to PPV resistance will facilitate the breeder to obtain resistant apricot cultivars. | |
