their flattened shape, which renders them somewhat difficult to pack 
satisfactorily under present commercial methods. 
LONG STRAIN 
The trees of the Long strain of the Valencia orange do not differ 
from those of the normal strain in observed characteristics of habit 
of growth or foliage development. The fruits of the Long strain 
have a somewhat cylindrical shape and are longer in comparison 
with their transverse diameter than is the case with fruits of the 
normal strain. 
There is more or less variation in the shape of fruits produced by 
trees of the Long strain, as is also the case with the trees of the 
Flattened strain of the Valencia orange. There is a marked tend- 
ency toward the production of oblong fruits in trees of the Long 
strain, but so far as studied these trees also produce some fruits of 
approximately the normal shape as well as others more or less inter-

mediate so far as the typical long and normal shape of fruits is 
concerned. 
In Table 7 are presented the performance records of eight progeny 
trees which were propagated from five limb variations bearing 
oblong fruits in otherwise apparently normal Valencia trees. It will 
be noted in this table that all of the progeny trees of the limb varia- 
tions have produced fruits of both Long and Valencia strains each 
season during the performance-record period. In the case of progeny 
trees Nos. 11-15 and 11-16 the tendency has been to produce a large 
proportion of Long strain oranges, as has also been true of progeny 
trees Nos. 12-29 and 12-31. On the other hand, progeny trees Nos. 
11-28 and 12-24 have produced a greater total number of fruits of 
the Valencia strain than of the Long strain. Typical fruits of 
the Long strain produced by one of these progeny trees are shown in 
Figure 9.
