ancestry

Cross of Vitis rupestris × Vitis riparia by Pierre-Marie Alexis Millardet and Charles de Grasset, France, 1882.

This document comes from the crossing series "101", which was carried out by Alexis Millardet at the University of Bordeaux in 1882. As the parent of the crosses, he used Vitis Rupestris as the mother and Vitis Riparia as the father variety. From this he received 21 seedlings, the offspring of which were propagated until 1892 as a mixed set on the vineyards made available by Charles de Grasset. From this, Prosper Gervais then selected "101-14" in 1893, which turned out to be the best base for this series of crosses.

Properties - use

It has a weak to medium-strong growth. It prematurely ripens the grapes and is tolerant of waterlogging in spring. It is very sensitive to drought and not well tolerated by lime and has a very low level of resistance to the root aphid.

It is well suited as a rootstock for salty soils, also for clayey fertile soils in early, not too dry locations.

Synonyms

Designations for the variety contain the number "101-14" and often an abbreviation "MG", "MGT" or the crossbreeding of Riparia and Rupestris in different spellings.
