TESTING GEAPE VAEIETIES IN THE VINLEEEA EEGIONS. 



129 



Table IX shows additional tests of improved American native and 

 Franco-American grape varieties grafted on resistant stocks which 

 are being made at the Fresno and Oakville experiment vineyards. 

 (See PI. I, figs. I and 2.) Arabic figures are used to indicate the 

 number of different stocks upon which each is grafted and the location 

 of the same. The tests are too young to permit the drawing of 

 conclusions.

The explanation of columns already given for Table VII will apply 

 for the most part to Table X, showing the relative behavior and value 

 for different purposes of improved American native and Franco- 

 American grape varieties, except that the parentage of the varieties 

 displaces the designation of the stock, the column for the "Year 

 grafted" is omitted, and the congeniality column is changed to a 

 growth-rating column, because all the varieties are on their own roots. 

 The column for weight of pruning is also omitted. The abbreviations 

 used to designate the parent species are as follows: Aest. for Aesti- 

 valis, Bourq. for Bourquiniana, Champ, for Champini, Lab. for 

 Labrusca, Lins. for Linsecomii, Rip. for Riparia, Rup. for Rupestris, 

 Vin. for Vinif era.
