Abstract

Based on an inventory of the still existing traditional fruit accessions in Malus domestica, Pyrus communis, Prunus avium and Prunus domestica and their subsequent preservation in decentralised Swiss fruit genetic resources collections, the accessions were genotyped and phenotyped.
Microsatellite marker data was established on 2495 accessions of apple, 1302 accessions of pear, 860 accessions of cherry and 399 accessions of plum from 6 different repositories in Switzerland.
They allowed the identification of duplicates that ranged between 41 to 70% depending on the fruit species.
Additionally, susceptibility and resistance to apple plant diseases (scab, powdery mildew and fire blight) were evaluated for subsets of selected genotypes.
Here we report on the fire blight shoot inoculation test in the glasshouse of 38 accessions.
