In the reference 9 varieties crop Vitis berlandieri Planch x Vitis rupestris Scheele, where this is mentioned in the description.

Vitis berlandieri x Vitis rupestris hybrids demonstrate pronounced resistance to root system infestation by phylloxera. Unlike the European species Vitis vinifera, these rootstock forms are capable of effectively limiting pathogen development on the roots due to the presence of natural defense mechanisms.

The resistance of these hybrids to phylloxera is a quantitative trait; specific named resistance genes or individual pathotypes capable of overcoming the defense of this particular hybrid group have not been identified in scientific literature. The crop maintains the status of a stable rootstock with complex resistance, combining high vigor and adaptability to various soil conditions.
