Plant resistance to aphids can be improved by introgressing resistant traits from wild Solanum species into the potato germplasm. Breeding parents are commonly selected from the different accessions of each species. Accessions originate from several seeds collected in a restricted area and are conserved as seeds in genebanks. Genetic heterogeneity may be expected between genotypes from the same accession and...
