| Abstract: | The potential for introgression of Prunus davidiana, a wild species related to peach, was evaluated with respect to problems of non-Mendelian segregation or suppressed recombination which often hamper breeding processes based on interspecific crosses. Three connected (F1, F2 and BC2) populations, derived from a cross between P. davidiana clone P1908 and the peach cultivar Summergrand were used. The intraspecific map of P. davidiana already established using the F1 progeny was complemented, and two interspecific maps, for the F2 and BC2 progenies, were built with a set of markers selected from the Prunus reference map. With the molecular data collected for the F2 map construction, regions with distorted marker segregation were detected on the genome; one third of all loci deviated significantly from the expected Mendelian ratios. However, some of these distorted segregations were probably not due to the interspecific cross. On linkage group 6, a skewed area under gametic selection was most likely influenced by the self-incompatibility gene of P. davidiana. Using anchor loci, a good colinearity between the three maps built and the Prunus reference map was demonstrated. Comparative mapping also revealed that homologous recombination occurred normally between P. davidiana and the Prunus persica genome. This confirmed the closeness of the two species. Higher recombination rates were generally observed between P. davidiana and P. persica than between Prunus amygdalus and P. persica. The consequences for plant breeding strategy are discussed. The three maps of the F1, F2 and BC2 progenies provide useful tools for QTL detection and marker-assisted selection, as well as for assessing the efficiency of the peach breeding scheme applied to introgress P. davidiana genes into peach cultivated varieties.
