FIXAL SELECTION 61 



A FEW PRACTICAL HINTS 



In selecting raspberry or blackberry plants 

 for color of fruit, for example, there is almost 

 always a correlation of the plant and fruit that 

 will foretell the future crop. 



I have observed in thousands of instances that 

 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 sought. 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 tendrils may give clear indication of the 

 size and flavor of the future bunches of fruit.
