Evaluation of strawberry cultivars for resistance to Verticillium dahliae Kleb
نویسندگان
چکیده
Verticillium dahlia Kleb. is a soil-borne pathogen which causes worldwide economically important plant and yield losses. So far no resistance preventing the fungus from growing in the plants could be found in the genus Fragaria. But there are cultivars with different levels of tolerance. In particular after the ban on chemical control with effective soil disinfectants (methylbromid) cultivation methods and the breeding of tolerant cultivars become important. In this experiment, 21 strawberry cultivars were inoculated under greenhouse conditions with a suspension of seven Verticillium dahliae isolates from various regions of Germany and from Poland. The isolates belong to different genetic groups as first investigation by RAPD analysis reveals. After resistance evaluation strawberry cultivars were scored in three resistance classes: “highly tolerant”, “medium susceptible” and “highly susceptible”.

EFFICACY OF RESISTANCE SELECTION TO VERTICILLIUM WILT IN STRAWBERRY (Fragaria x ananassa Duch.) TISSUE CULTURE
The soil-borne pathogenic fungus Verticillium dahliae Kleb. causes economic losses in crops in temperate regions of the world and hence is the most studied species. Strawberry (Fragaria x ananassa Duch.) belongs to plant species susceptible to Verticillium dahliae, although the response to infection caused by this pathogen is varied and depends on the cultivar. Due to a lack of efficient method...

Verticillium dahliae Kleb. the causal agent of vascular wilt is an important pathogen of olive trees in growing areas of the world. Nine-month-old nursery olives including ‘Bladi’, ‘Conservalia’, ‘Kalamon’, ‘Koroneiki’, ‘Manzanilla’, ‘Mission’, ‘Marry’, ‘Picual’, ‘Rowghani’, ‘Sevillana’ and ‘Zard’ cultivars were root-dip inoculated with a defoliating (VCG1) isolate of V. dahliae obtained from d...

Verticillium wilt is a vascular disease predominantly caused by the soil-borne fungi Verticillium dahliae and Verticillium albo-atrum. Most of the commercial potato cultivars grown in the USA are susceptible to Verticillium, resulting in significant crop losses. Development of new cultivars with resistance gene(s) against the pathogen can be assisted with molecular marker technology that allows...
