Turkey has a very old history of viticulture and also homeland of the grapevine (Vitis spp.). Vitis cultivars belonging to different species are grown in almost every region in the country. However, particularly downy mildew and powdery mildew diseases affect the cultivars belonging to Vitis vinifera. In northern of Turkey Vitis labrusca and hybrids between V.vinifera and V.labrusca are rather common. V.labrusca cultivars or genotypes exhibit generally higher degree of resistance than V. vinifera cultivars. However, resistance level can vary from cultivar to cultivar and even from clone to clone within one cultivar. In this study, different Vitis hybrids and genotypes which exhibit different downy and powdery mildew susceptibility are compared for two years. Especially some V.labrusca hybrids and genotypes appeared resistance for both diseases. On the other hand, interspecific crosses and V.vinifera cultivars were found to be more susceptible. Using resistant lines as parent in later breeding activities, it could be possible grow high quality table cultivars with much fewer pesticide applications or possibly without them.
Resumo
A Turquia tem uma longa história vitícola, sendo inclusivé um dos pontos de origem da videira (Vitis spp.). As diferentes espécies de Vitis são cultivadas em quase todas as regiões do país. Doenças como o míldio e oídio afetam em particular as videiras pertencentes à espécie V.vinifera. No Norte da Turquia, as espécies Vitis labrusca e híbridos entre V. vinifera e V. labrusca são bastante comuns. As cultivares/genótipos de V. labrusca exibem um grau de resistência geralmente mais elevado do que as cultivares de V. vinifera. No entanto o nível de resistência pode variar de cultivar para cultivar e até mesmo de clone para clone dentro de uma mesma cultivar. Neste estudo foram comparados diferentes híbridos de Vitis e genótipos com diferentes suscetibilidades ao míldio e ao oídio por um período de dois anos. Alguns híbridos e genótipos de V.labrusca apresentaram resistência a ambas as doenças. Por outro lado, os cruzamentos interespecíficos e as cultivares de V.vinifera foram identificados como sendo mais susceptíveis. Usando linhas resistentes como linha parental em atividades de melhoramento posteriores, poderia ser possível desenvolver cultivares para produção de vinhos de mesa de alta qualidade com menores exigências de aplicações de pesticidas ou possivelmente sem eles.
