BUD SELECTION IN THE VALENCIA ORANGE 
33 
In these progeny studies the quantity of fruit produced generally 
has been found to be correlated with its market quality. The high- 
yielding trees have been found to bear consistently a high percentage 
of first-grade fruit, and the low-yielding trees have borne a small pro- 
portion of first-grade oranges. In the high-yielding trees the large 
proportion of the fruit has usually been of the desirable medium sizes 
and of the most desirable shape for packing. In the case of the low- 
yielding trees there has been a tendency to produce fruits of ex-

tremely large or abnormally small sizes and of irregular shapes 
which are not so well adapted for packing under present methods 
as the shape typical of the Valencia strain. 
The characteristics of the foliage of the limb variations studied in 
these progeny tests have been perpetuated in a manner similar 
to those of the fruits. In some instances, as for example in the case 
of the Willow-Leaf strain, the characteristics of the foliage are 
correlated with certain characters of the fruits, so that it is possible 
to identify such limb variations by either the foliage or the fruits.
