IQO AMERICAN VINES. 



Millardet and de Grasset also obtained a great number of 

 similar hybrids. 



Gros Col man X Rupestris A?o 160 are more vigorous 

 than the Rupestris hybrids so far tried in the chalky soils 

 of the Charentes; they also become less yellow, although 

 useless for those soils. They root very freely from cuttings, 

 the grafts knit well, and are very fructiferous. In the groies 

 soils of the Charentes they are better, and do not become 

 yellow, whether grafted or not. The development of their 

 grafts is very satisfactory ; but Millardet has ascertained that 

 their resistance to phylloxera is not sufficient. 



Cabernet X Rupestris No. 33 are also -very vigorous and 

 fairly resistant to chlorosis. 



Alicante-Bouschet X Rupestris No. 139 are less well 

 adapted to chalky soils, and become yellow in groies soils. 



Alicanle-Bouschet y: Rupestris No. 136 of the School of 

 Agriculture, Montpellier. Has a powerful vegetation, but is 

 not adapted to calcareous soils, and could, therefore, only be 

 cultivated in compact, siliceous, and non-calcareous soils, for 

 which the pure species is still superior. These hybrids 

 seem to be the best as far as resistance to phylloxera is 

 concerned. 



We might, again, mention many other hybrids of Vinifera 

 and Rupestris obtained by Millardet, de Grasset, Couderc, 

 Castel, the School of Agriculture, Montpellier, Terras, etc. 

 As a matter of fact considerable numbers of these hybrids 

 have recently been created; the Rupestris, on account of its 

 great vigour, has been much utilized as a hybridizing agent 

 in binary, ternary, or more complex combinations. What 

 has just been said will suffice to give an idea of the general 

 properties of adaptation of this group. We cannot study all 

 its forms. 



A few, however, have been advocated as direct producers, 

 such as Franc's Hybrid, Alicante X Rupestris Terras No. 

 20, etc. These vines are relatively fructiferous as far as the 

 number of grapes is concerned, but the yield is always small 

 compared with that given by the European vines, and, more- 

 over, the quality of their wine is inferior to that of the most 

 common French wines. The colouring matter of the wine 

 from these hybrids is sometimes very intense ; but it has 

 the defect of all Rupestris produce, that of rapidly attenuating. 

 Their resistance to phylloxera has not yet been ascertained.
