Grapevine cultivars

Three indigenous grape varieties are typically grown in the region Cor-vina, Rondinella, and Molinara. Their characteristics possess attributes facilitating production of the traditional red wines of the region, that is, Valpolicella, Recioto, and Amarone. 

The following provides a brief description of the most widely grown cultivars in the region.

The varietal composition of Amarone (Anonymous, 2010) stipulates that the content of Corvina can vary from 40% to 80% Corvinone can replace Corvina by up to 50% and Rondinella can vary from 5% to 30%. Up to 15% can come from other local grape varieties (each within a limit of 10%).

We are continuing our efforts to identify both inducing and inhibitory compounds from grapevine cultivars and other hosts of Agrobacterium. With a more complete understanding of the chemical signals involved, it should be possible to induce Ti-mediated transformation in virtually any plant species. Clearly such a distant goal will also require a synthesis of data from a number of fields of research.

In former times, no quarantine or border inhibited the spread of new grapevine cultivars. The exchange of material could easily happen. In Mid Europe, cultivars from far away had the chance to become established, and in some cases, they are still cultivated today. Prominent imports done centuries ago are the Pinot family (Jahnke et al., 2011) or Portugieser (Regner et al., 1999). The most important argument to keep a...

An important collection of grapevine cultivars is also at the Faculty of Horticulture in Lednice na Morave. This collection involves, above all, interspedlic cultivars of V. vinifera xVitis amurensis, V. vtm/crax Fiench-American hybrid vines (Seibel, Seyve Villard, Baco, etc.) and V. viniferaxV. amurensisxFrench-Amencaa hybrids. This collection involves -300 cultivars and hybrids. 

The evaluation of genetic sources from the viewpoint of their resistance to fungal diseases, for example to downy mildew (Plasmopara viticola), was also performed under field conditions. In this study, the resistance to downy mildew of 44 grapevine cultivars was evaluated in a long-term field experiment (1996-2003). The resistance was evaluated under conditions of a natural infection pressure using the OlV 452 scale on the one hand and on the base of the evaluation of disease incidence of sporulation and disease incidence of necrosis on the other (Table 10.1).

A mutual crossing of inbred lines of different grapevine cultivars resulted in the creation of two new cultivars (Hetera and Inzuchta).
