RIPARIA X RUPESTRIS 3306 AND 3309. 



These hybrids, raised by Conderc of Aubenas, have proved 

 very vigorous and resistant to phylloxera. They grow well 

 in calcareous soils, where all Riparias and most of the 

 Rupestris become yellow, and they bear very fructiferous 

 grafts. With regard to resistance to limestone they are 

 equivalent to the Rupestris du Lot, and withstand pourridie 

 better than the latter. It was noticed in 1897, in the Aude, 

 that folletage had generally affected all the vines grafted 

 on Riparia x Rupestris 101-14, while those grafted on 3309 

 were not subject to this accident. Under these circum- 

 stances these stocks may be considered as excellent graft 

 bearers capable of giving good results in soils which are too- 

 calcareous for Riparia and for certain Rupestris, and not 

 calcareous enough to necessitate the use of V. Berlandieri, 

 and sometimes too wet for the Rupestris du Lot. 



RIPARIA x RUPESTRIS 101-14. 



This hybrid was obtained by Millardet and de GrasseL 

 It shares the same qualities as the two above described, 

 except that its grafts have a tendency io folletage. 



RUPESTRIS WITH TAYLOR HABIT. 



This form, selected at Mas de las Sorres, seems to be a 

 hybrid between the V. ^Estivalis and the V. Rupestris. Its 

 resistance to phylloxera is 16. It is a very vigorous plant 

 with strong trunk and spreading habit. Its canes are 

 sinuous, strong, deep hazel colour, with bloom around the 

 nodes. The leaves are large, wide, thin, long, orbicular, 

 thick, fleshy, goffered between the sub-veins, light and 

 dull green on the under-face, with strong veins covered witli 

 stiff hair, petiolar sinus deep lyre shaped. 



(D). FORMS DERIVED FROM V. BERLANDIERL 



It is only since the viticultural mission ofViala to the 

 United States in 1887, that attention has been directed to 

 the V. Berlandieri, and that a selection to obtain forms more 

 resistant to the action of limestone started. According to 

 Viala the general characters of the forms resisting limestone 

 are : leaves slightly tornentose, of a shining golden yellow. 

 The types most in use are : The B. Resseguier No. 1, B. 

 Resseguier No. 2, B. Daignere,B. of Angeac, B. Viala, and 

 B. Ecole.
