“…1. First, several major resistance genes, which had been mapped previously were positioned on the map: Vf, Va, and Vb on LG-1 (Maliepaard et al, 1998;Hemmat et al, 2003), Vr2, Vr, Vh8 and Vbj on LG-2 (Patocchi et al, 2003;Bus et al, 2004), Vd on LG-10 ( Tartarini et al, 2004), and Vg on LG-12 (Calenge et al, 2004).…”

In the frame of the D.A.R.E. project, five mapping populations have been studied for partial scab resistance against several races of Venturia inaequalis. A main objective was to identify QTLs (quantitative traits loci) with broad spectrum of resistance towards a wide range of strains of the fungus. Genetic markers (mainly SSR and AFLP) were tested on each population and genetic maps were constructed for both parents of each population. Meanwhile, pathological tests with several isolates of different races of V. inaequalis were performed. Four major genomic regions appear to be involved in scab resistance: they are located on linkage groups (LG) LG-1, LG-2, LG-11, and LG-17. Some other linkage groups carry either QTLs or major resistance genes that are isolate specific: a QTL on LG-5, Vd on LG-10, and Vg on LG-12. The QTL region located on LG-17 clearly exhibited the widest spectrum of resistance.

“…172632, and the major gene Va from 'Antonovka' P.I. 172633 mapped by Hemmat et al (2003) on LG-1 is another argument in favour of major genes and QTLs being different alleles of a single locus or different paralogs of a resistance gene family. Finally, two regions with broad spectrum of resistance were identified on LG-11 and LG-17.…”

“…Molecular markers have been developed for the identification of resistance genes to scab in the apple genome (Gessler et al 2006). There is a possibility to detect PCR molecular markers of resistance genes Va (Hemmat et al 2003), Vf (Tartarini et al 1999), Vm (Cheng et al 1998), Vbj (Gygax et al 2004), Vr1 (Boudichevskaia et al 2006), Vh4, Vr2 , Vh8 and Vh2 (Bus et al 2005).…”

Abstract:The presence of genes for resistance to scab (Venturia inaequalis) and powdery mildew (Podosphaera leucotricha) was studied using molecular markers in a sample of 279 apple cultivars from the Czech collection of apple genetic resources. The sample comprised 37 cultivars supposed to have the Vf gene for scab resistance, 97 reference world cultivars and 145 old and local cultivars. Six PCR molecular markers for the scab resistance genes Vf, Vm, Vbj, Vr and Vh and three PCR molecular markers for the powdery mildew resistance genes Pl-w, Pl-1 and Pl-d were used. The marker for the major scab resistance gene Vf was detected in all cultivars supposed to have Vf, except in Romus 1, and in the three small-fruited cultivars Malus Evereste, Golden Gem and Hilleri. The markers of the Vr and Vh scab resistance genes were detected in 22 cultivars in combination with the marker for Vf, in 56 reference world cultivars and in 82 old and local apple cultivars. PCR molecular markers for one or two of the powdery mildew resistance genes were detected in the small-fruited cultivars Malus Evereste, Golden Gem, prof. Sprengeri and Hilleri; and in the larger fruited cultivars Hagloe Crab, Borovinka and Tita Zetei. We did not find markers for the scab resistance genes Vm and Vbj in any of the studied cultivars. They are absent also in the remaining part of the Czech collection of apple genetic resources. PCR molecular markers are useful tools for the identification of resistance genes within apple germplasm collections and can be used to increase the number of sources for disease resistance in breeding programmes.

“…The Va-linked RAPD marker P-136 reported by Hemmat et al (2003) was also analyzed in the population 2000-012C to test its association with Vd3. RAPD amplification was performed in a GeneAmp® PCR System 9700 thermal cycler (Applied Biosystems) as described in Hemmat et al (2003).…”
