Genetic architecture of cherry leaf spot (<i>Blumeriella jaapii</i>) resistance in sour cherry (<i>Prunus cerasus</i> L.) uncovered by QTL analyses in a biparental population genotyped with the 6 + 9 K SNP array.

ABSTRACT: Sour cherry (Prunus cerasus L.) is an economically significant species in the Rosaceae family. Hitherto, there had been limited genetic and genomic resources to elucidate important horticultural traits in this species mainly because of the complex polyploid nature of its genome, a hybrid between Prunus avium and Prunus fruticosa. An important trait that has not been well studied in sour cherry is resistance to cherry leaf spot (CLS), caused by the fungus Blumeriella jaapii. This work took advantage of the RosBREED 6 + 9 K SNP array to study the genetic basis of CLS resistance and inheritance in sour cherry. We established an F ₁ segregating population by crossing two cultivars, 'Schattenmorelle' and 'Pc 2' and genotyped both parents and the pro
