Abstract

Powdery mildew, caused by Sphaerotheca pannosa var. Persicae, is one of the most important diseases in apricot production areas around the world. The transmission of resistance to powdery mildew and the identification of related quantitativetrait loci (QTLs) were analysed during 3 years in two F1 apricot progenies derived from the crosses ‘Bergeron’ 9 ‘Currot’ (B 9 C) and ‘Goldrich’ 9 ‘Currot’ (G 9 C). Field evaluation showed the great variability and segregation in each apricot population in terms of powdery mildew symptoms, demonstrating the polygenic nature and quantitative inheritance of this trait. In accordance with this polygenic nature, several related QTLs were detected using the Kruskal–Wallis non-parametric test, with two main genomic regions are involved in powdery mildew resistance in apricot. Two identified QTLs were mapped in the genetic linkage groups 2 (LG2) and 3 (LG3). In addition, in LG2 we can highlight the single nucleotide polymorphism (SNP) S2_18992724, which shows a strong influence in the presence-absence of disease. Finally, other linkage groups such as LG1, LG5 and LG6 were also related to different levels of expression of powdery mildew symptoms, but their influence appears to be less significant.
