| 520 | _ | _ | |a Erysiphe necator Schwein is a fungus that causes grapevine powdery mildew. It is one of the most problematicpathogens attacking Vitis vinifera L. The pathogen infects all green parts of the plant and reduces grape yieldand quality. The suppression on mildew-susceptible cultivars requires intensive use of fungicides againstpathogen, which has negative impact on the environment and human health. The identification, quantification,and use of host resistance is therefore a research priority favored by grape growers, genetics, breeders andwinemakers, governments, regulatory and grant agencies.At the end of 19th century, the breeding programs were carried out by crossing V. vinifera with resistantspecies, and in particular with North American Vitis that co-evolved with the pathogen. However, obtainedhybrids were mostly unsuitable for the production of high-quality wines, due to their unpleasant foxy aromas.Nearly all major cultivars of V. vinifera exhibit little evidence of strong genetic resistance against E. necator, withthe exception of ontogenic resistance that appears to be a universal trait. However, recent studies haveindicated that certain V. vinifera cultivars of Caucasus and Central Asian origin exhibit an unusual degree of fieldresistance to powdery mildew. Some Georgian V. vinifera accessions from the South Caucasus have beenreported to be resistant to E. necator and to have no known genetic relationship to non-vinifera species. Theaim of our preliminary research was to quantitatively measure the field resistance of local Georgian varieties topowdery mildew, as a necessary first step to more in-depth phenotyping and genetic studies. |
