Effect of the scab inoculum and the susceptible parent on resistance to apple scab (Venturia inaequalis) in the progenies of crosses to the scab resistant cv 'Florina' [PDF]

open access: yesAgronomie, 1993
La création de variétés de pommes résistantes à la tavelure est très importante en vue de diminuer les interventions phytosanitaires dans les vergers. Pour que la résistance soit durable, il est indispensable de tester différents inoculums et de définir les meilleures stratégies d’amélioration génétique. Nous avons inoculé en serre, avec une suspension

An apparent breakdown of Vf resistance occurring in an apple orchard in Bistrita area

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture, 2022
Scab resistance through the Rvi6 gene was largely used in Romanian breeding programs including those from Fruit Research & Development Station (FRDS) Bistrita. The aim of the study was to verify the efficacy of the resistance due to the Vf gene under the

Scab-Resistant Apples

open access: yesHortScience, 1977
Abstract Apple scab, caused by the fungus Venturia inaequalis (Cke.) Wint. is one of the most economically important apple diseases, because of the annual loss of marketable fruit, tree debilitation as a result of foliage destruction, and the cost of chemicals, equipment ...

Is it feasible to use mixed orchards to manage apple scab?

open access: yesFruit Research, 2023
Apple scab, caused by the fungus Venturia inaequalis, is one of the most damaging diseases of cultivated apples (Malus x domestica) worldwide. It results in huge losses as it diminishes fruit quality and impacts tree growth.

Scab Resistance in some Apples Genotypes from the UASVM Collection Cluj-Napoca

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture, 2023
Apple is one of the most consumed fruits in the world and as well one of the most important crops in temperate areas. Apple scab, caused by Venturia inaequalis is damaging diseases that affects apple species and causes up to 70% yield losses depending of

Apple Contains Receptor-like Genes Homologous to the Cladosporium fulvum Resistance Gene Family of Tomato with a Cluster of Genes Cosegregating with Vf Apple Scab Resistance

open access: yesMolecular Plant-Microbe Interactions, 2001
Scab caused by the fungal pathogen Venturia inaequalis is the most common disease of cultivated apple (Malus × domestica Borkh.). Monogenic resistance against scab is found in some small-fruited wild Malus species and has been used in apple breeding for ...

Two Receptor-Like Genes, Vfa1 and Vfa2, Confer Resistance to the Fungal Pathogen Venturia inaequalis Inciting Apple Scab Disease

open access: yesMolecular Plant-Microbe Interactions, 2008
The Vf locus, originating from the crabapple species Malus floribunda 821, confers resistance to five races of the fungal pathogen Venturia inaequalis, the causal agent of apple scab disease. Previously, a cluster of four receptor-like genes, Vfa1, Vfa2,

Identification of apple scab and powdery mildew resistance genes in Czech apple (Malus × domestica) genetic resources by PCR molecular markers

open access: yesCzech Journal of Genetics and Plant Breeding, 2011
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.

Selection of promising apple genotypes for columnar growth habit and scab resistance using diagnostic DNA markers

open access: yesВавиловский журнал генетики и селекции, 2016
Monogenic scab resistance and columnar growth habit are important breeding traits of apple. The use of molecular markers very accurately determines the presence of necessary genes in the genome early during ontogenesis and reduces the time of selection ...
