Table 4. Classification of rootstocks on the base of the content of active lime and CPI (Juste & Pouget, 1972. In: Huglin
& Schneider, 1998).

Recently, the species Vitis cinerea is very often used when selecting new rootstock types. In the
Czech Republic, rootstock breeders used the German rootstock Börner and the Czech hybrid
Bruci [( Vitis berlandieri x Vitis rupestris) x Vitis cinerea ] as donors of resistance to phyloxera.
Hybrids with a very high tolerance to chlorosis originated from parent combinations [Binova
x (Binova x Teleki 5C) x Börner] and (Teleki 5C x Börner). These hybrids originated from
combinations of Vitis berlandieri, Vitis riparia and Vitis cinerea . Hybrid combinations with Vitis
rupestris and Vitis amurensis showed mostly only a medium tolerance to chlorosis. A simple
hybrid (Binova x Börner) showed also a medium tolerance to lime-induced chlorosis
(Pavloušek, 2009).

4. Tolerance of grape rootstocks to drought

Drought stress is one of the most important abiotic stress factors which are generally accom‐
panied by heat stress (Zulini et al ., 2007).

In recent years, climatic changes can be observed worldwide. Warm years are more frequent
and periods of drought are longer. This means that modern viticulture must look for methods
how to react to this increasing frequency of periods of drought.
