“…Vf and Va scab resistance genes have been closely mapped on LG1 (Gessler et al 2006) and it is possible that Vf molecular marker identified Va scab resistance gene or another allele of Vf scab resistance gene (e.g. Vd3 - Soriano et al 2009). Cultivar Dukát was derived from the crossing of cultivars Golden Delicious × Cox,s Orange Pippin (Zoufalá et al 2009).…”

“…Crosby et al (1992) suggested that Romus cultivars could contain only a high level of polygenic resistance and not the Vf scab resistance gene. There are also possibilities of the absence of molecular marker on LG1, presence of different allele of Vf resistance gene or Va resistance gene (Gessler et al 2006;Soriano et al 2009). But the used PCR molecular marker of Vf scab resistance gene (Tartarini et al 1999) was not in tight linkage to Va resistance gene, which is present in the scab resistant cultivar Produkta, which was not amplified (Table 3).…”

“…Most of the commercial apple cultivars are susceptible to fungal diseases, and growers have to apply fungicides 20-30 times per season. The use of resistant cultivars could cut growers' costs and might also contribute to a cleaner environment and to a reduction of fungicide residues on apples for consumers (Soriano et al 2009). …”

“…The sources of scab resistance are cvs Golden Delicious (Vg), Antonovka (Va), GMAL 2473 (Vr2), Durello di Forli (Vd), 1980-015-25 (Vd3), Mildew Immune Selection (MIS) (Vmis), differential host 2 (Vh2) and host 4 (Vh4) (derived from M. pumila R12740-7A), M. sylvestris W193b (Vh8) (Gessler et al 2006). Resistance genes Va, Vf and Vd3 have been mapped on LG1; Vbj, Vr, Vr2, Vh2, Vh4 and Vh8 have been mapped on LG2; Vmis has been mapped on LG3; Vd has been mapped on LG10; Vb and Vg have been mapped on LG12 and Vm has been mapped on LG17 (Soriano et al 2009). Recently, scab resistance genes have been renamed to Rvi genes, according to gene-for-gene relationships in the V. inaequalis-Malus pathosystem (Bus et al 2009) and currently there are about 17 known genes (Bus et al 2010).…”

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.

“…Fungicides applied during spring and summer are used to control scab dieases caused Vinaequalis in apple orchards in Turkey (Boyraz et al, 2005). Most of the commercial apple cultivars are susceptible to the disease, and growers have to spray 20-30 times with fungicides in a season (Boyraz et al, 2005;Soriano et al, 2009). The use of pesticides adversely affect useful insects, microorganisms, plants, water, and even human health.…”

Content: Phenolic compounds play an important role in the plant defense mechanism and are responsible for antioxidant capacity in fruits and vegetables. It is known that the phenolics can determine in the leaves of plants which are resistant/susceptible to fungal infections. Objective: This study investigated the total phenolic compounds, content of shikimic acid from 33 different apple cultivars leaves infected with Venturia inaequalis [(Cke). Wint.] cultured in Fruit Research Station, in Egirdir, Isparta, Turkey. Materials and methods: Leaves of apple cultivars were collected three times in an interval of 30 d from July to September in 2010, and analyzed using HPLC methods to detect changes in the amount of the phenolic compounds and shikimic acid. Results: Total phenolic compounds and shikimic acid in resistant/moderate susceptible apple cultivars were higher than susceptible apple cultuvars, although not statistically different between resistant and susceptible apples. The content of shikimic acid was statistically higher only in the leaves of the domestic cultivar Ankara gü zeli on all three dates. Discussion and conclusion: Recently, there have been increased studies trying to explain the resistance mechanism in plants. Natural resistance genes are investigated in some apple cultivars and new resistance varieties which have resistant genes are identified daily. Our study hold to determine the relationship between the phenolic compounds and the expression of resistance seems to be promising.
