Riparia x rupestris 101‑14 is a medium-sized rootstock for grapevines, created in France and widely distributed in European gardens. The bushes are characterized by dark brown shoots, which are upright and knee-bent, while the leaves have a matte texture, are of medium size, and slightly curve along the central vein with widely scalloped edges.
The variety is distinguished by high resistance to fungal diseases: downy mildew, powdery mildew, and phylloxera. The root system is branched but not too powerful, which allows the vine to develop well even in soils with a moderate concentration of soluble carbonates (up to 9%). The frost resistance of the roots and buds is high, while drought resistance is at a medium level.
Successful cultivation requires complex agronomy: regular suckering, pinching, and timely insecticide treatments due to high susceptibility to the leaf form of phylloxera. With proper care, the vine reaches 80% fruit maturity, and the total volume of annual growth is about 1100 cm³. The rootstock grafts well with most European varieties and is suitable for creating hybrid vineyards.
