vines that have purple spines and canes will in 

 future produce berries that are dark purple or 

 dark red in color. Pinkish leaves, on the other 

 hand, foretell fruit of light pink or red color; 

 plants with yellowish vines and foliage may be 

 expected to produce berries of a yellowish color. 

 Very pale foliage and canes usually indicate that 

 the crop will be of a whitish or amber color. 



A knowledge of this correlation between vine 

 and fruit was of great service to me in my later 

 experiments for the development of the race of 

 white blackberries. It enabled me to select for 

 transplantation and particular care vines that 

 would produce the type of berry I was seeking. 

 It was not necessary to await the time of fruiting 

 in order to gauge progress. 



The correlation of characters between the vine 

 and the fruit of the grape is not always quite 

 so clearly established, yet it is often observable. 

 Grape tentacles may give clear indication of the 

 size and flavor of the future bunches of fruit. 

 Long before a grape vine has come to the age 

 of fruiting, the taste of the tendrils may give 

 a fair idea of the flavor of the grapes it will 

 ultimately bear. 



Moreover the seedling vines that produce bushy 

 stems that are small and much branched, and 

 have small leaves, will almost invariably produce
