Origin of resistance to plum pox virus in Apricot: what new AFLP and targeted SSR data analyses tell
Original language description
Amplified fragment length polymorphisms (AFLP) and targeted simple sequence repeats (SSR) were employed to assess genetic similarity of North American apricots having natural resistance to plum pox virus (PPV) within diversified germplasm including six nondomesticated apricot species. On a dendrogram constructed from 231 AFLP loci, the position of the North American cultivars reflects relatedness to the European apricots and introgression of non-European germplasm as well. The occurrence of diagnostic AFLP markers supports an introgression of Chinese germplasm into the North American PPV resistant assortment and supports a different breeding history for 'Stark Early Orange' (SEO) and Goldrich-Harlayne lineages. Five SSR loci linked to the PPV resistance region on G1 provided evidence that the investigated lineages (SEO and 'Harlayne'-'Goldrich') have the same or related source of resistance introduced presumably from Northern China. Possible introgression of genetic material from nondo
