European pear, SSR, linkage map, synteny

European pear is one of the most important fruit species but to date very limited genetic studies have been done. Many reports suggest that simple sequence repeats (SSR) are very useful as markers because they are codominant, highly polymorphic, abundant and reproducible. In the present work it is reported the transferability data of more than one hundred SSR markers in two progenies of European pear (‘Passe Crassane’ x ‘Harrow Sweet’ and 'Abbè Fétel' x 'Max Red Bartlett'). A total of 41 SSR markers have been positioned on a genetic linkage map of former cross population and 20 in the latter one (in this case the mapping work is still in progress). The degree of synteny among the chromosomes that carry two or more SSR markers have been analysed. The alignment of the pear and apple maps both in respect to identification as well as to orientation of the linkage groups confirmed the co-linearity between the two genomes.
