| Abstract:
The first interspecific crossing at the experiment station in Sremski Karlovci was made in 1975. Since then, more than 100 combinations were raised. Beside Vitis vinifera germplasm, genes from East-Asian species Vitis amurensis and several species originated from North America were used. Cultivars Kunbarat and Kunleany were the main donors of V. amurensis, and Seyve Villard hybrids and cultivars derived from it for North-American germplasm. During these two decades, we made a few back crossings with the intention to increase the quality and to combine it with the resistance to the three main fungal diseases, with high cold hardiness and with grape maturity in early season. In this paper, several crossings are analysed from three successive generations developed at this experiment station by hybridisation in 1977, 1986 and 1990. The progeny of the last crossing (SK 90–2) contains 3,13% of V. amurensis, 6,25% of North-American species and over 90% of V. vinifera germplasm. Seedlings were raised and selected in field conditions without plant protection. The ratings were done for four years at the end of August in accordance with the IBPGR scheme. | |
