BUD SELECTION IN THE VALENCIA ORANGE 
The progeny trees were transplanted from the nursery in July, 
1917. They were set 10 feet apart in rows spaced 22 feet apart, the 
close planting in the rows making possible the testing of twice as 
many progenies as would have been the case had the ordinary 
spacing been practiced. The planting is arranged so that when the 
trees reach such size as to interfere with cultural practices every 
alternate tree may be removed, thus attaining what is considered 
to be a normal spacing for this variety in this district. 
The trees in this progeny planting have been given ordinary culti- 
vation, irrigation, and other cultural care. Winter and summer 
cover crops have been grown each year with more than ordinary 
success and plowed under for the purpose of soil improvement. 
Very little fertilizer of any kind has been applied up to the present 
time, although it is believed that the use of additional organic 
fertilizer is now necessary. The trees have made normal growth 
thus far and have not suffered from serious frost damage at any 
time since their planting. Little or no injury from scale or other 
insect attack or from citrus-tree diseases has been observed, and 
the trees may be considered to have a somewhat better development 
than is usually the case in this region. 
PROGENY PERFORMANCE RECORDS 
In obtaining the performance records of the progeny trees propa- 
gated from the various bud variations, the fruits borne by each tree 
have been counted and classified annually according to their strain 
characteristics. For the last three years the weight of the crops has 
also been determined. 
The number of progeny trees of each propagation was limited by 
circumstances of planting, and while records from a larger number 
of trees would have been desirable, it is the opinion of the writers 
that reliable and economically sound conclusions can be drawn from 
the data available for consideration. The sets of progenies of the 
various strains will be considered separately in order to show more 
clearly the results of the propagation tests. 
UNPRODUCTIVE STRAIN 
In the Unproductive Valencia orange strain studied in these in- 
vestigations the type of fruit and the characteristics of the leaves 
are somewhat different from those of the productive or Valencia 
strain. The fruits are smaller in size and tend to be elongated or 
pear shaped with a thinner rind than is the case with normal fruits. 
The leaves on the Unproductive strain trees are somewhat smaller 
than those on normal 3 trees and are more acutely pointed. Also, 
the foliage on the trees and limbs of this strain usually shows a 
marked chlorotic condition in the winter months. 
In the limited number of trees in the original Valencia perform- 
ance-record plots from which buds were taken for these progeny 
propagations, no entire tree of the Unproductive strain was found. 
Later, in other performance-record studies in different Valencia

ing the characteristics of the Valencia or normal strain of the Valencia orange."
