;graft-bearers of great value for such soils.*' But other hybrids 

 <of Rupestris, Riparia or Cordifolia with Vinifera, which have 

 a more powerful root system, would thrive equally well in 

 similar soils. However, the Cinerea hybrids could only 

 render services in such soils if they were resistant to 

 phylloxera. 



One of the progenitors of V. Cinerea is very sensitive to 

 chlorosis, and the strain of Vinifera contained has not 

 endowed them with a very high resistance to that disease, 

 therefore they are useless for the chalky soils of the 

 Charentes. All those tried in these soils became yellow the 

 first year of planting out, and, when grafted, rapidly 

 .succumbed. They root freely and knit well. 



Hybrids of V. Vinifera, V. Labrusca, V. >stivalis, 

 and V. Cinerea. Millardet assumes that the Alvey is the 

 result of. the union of four species. The cepage is only slightly 

 resistant to phylloxera (resistance, 7) and is now only to be 

 found in collections. It is without interest. Let us note 

 that its resistance to chlorosis is small, inferior to that of 

 Jacquez or Blue Favourite, which is no doubt due to the 

 predominance of its American progenitors. 



Hybrids of V. Vinifera, V. >Cstivalis, and V. Cinerea. 



This group contains very well-known cepages of great 

 interest : the following list shows their resistance to 

 phylloxera :

of G. Bazille) Resistance, 3.

of Aurelle) Resistance, 9. 

 Jacquez, with large berries (cuttings of Jacquez Nos. I 



and 2, of Aurelle) Resistance, 9. 

 Herbemont Resistance, 13.
