Abstract
In this study we evaluated the hybrid family Rinot x BV-7-6-2 derived from different resistance donors, such as French-American hybrids and Vitis amurensis, in Czech Republic. The objective of this breeding program was to obtain white wine cultivar of high resistance and high quality level, suitable for high density plantations and production of sparkling wines, low-alcoholic or non-alcoholic wines, grape juices and concentrates. The cross combination was performed in 2003. In this population 54 seedlings were obtained. 13 promising genotypes with high resistance level to the main fungal diseases and high grape and wine quality were selected for further investigation. Genotype Markus was found to be the most interesting and is currently under registration in national catalogue. The new resistant cultivar is suitable for integrated and organic viticulture due to significantly reduced number of pesticide applications.
