BUD SELECTION IX THE VALENCIA ORANGE 
15 
yields of 626 and 546, respectively, for the two progeny trees of the 
Persistent-Style strain. From these data it will be seen that the tree 
of the Valencia strain has been almost twice as productive as the 
trees of the Persistent-Style strain.

The light production of fruit from the trees of the Persistent-Style 
strain has been correlated with inferior commercial quality on ac- 
count of the small size, undesirable shape, and poor color of the 
fruit. The persistent styles are also an undesirable feature from the 
commercial standpoint, because they are likely to be injured during 
picking or other handling operations, thus leading to the possible 
development of decay during transportation and marketing. 
FLATTENED STRAIN 
The trees of the Flattened strain of the Valencia orange do not 
differ in foliage characteristics, so far as observed, from those of the 
Valencia strain, their habit of growth, the number, size, shape, and 
distribution of their leaves being about normal. 
The fruits of this strain are markedly flattened at both the stem 
and blossom ends. This characteristic is not uniform for all of the 
fruits on the trees of this strain thus far studied, and fruits of normal 
shape have been found in the crops of all of these trees. On the 
other hand, in trees of the Flattened strain in Valencia orchards 
other than the one in which these investigations have been carried 
on, the writers have found instances where nearly all of the fruits 
have shown a decidedly flattened shape in contrast to the normal 
shape of fruits borne by other comparable normal trees in the same 
orchards. 
Flattened strain limb variations in otherwise normal trees were 
found in two of the trees in the original Valencia performance- 
record plots. The fruits from both of these limbs were not all 
flattened in any season during the period of individual-tree study. 
However, typical flattened fruits were found to occur in the crops 
produced by these limbs each season, together with normal ones and 
others having thick rinds and coarse texture. Xeither of the parent 
limbs have at any time been considered to be inherently stable. The 
four progeny trees propagated from these limbs have proved that
