BUD VARIATION IN THE VALENCIA ORANGE. 9 
CORRUGATED STRAIN. 
The trees of the Corrugated strain are not so productive, as a rule, 
as those of the Valencia strain. They have a drooping habit of 
growth, and the leaves are usually smaller than those of the Valencia 
strain and are sharply pointed. 
The typical fruits, as shown in Plate II, are oblong or cylindrical; 
size usually large; texture of skin very rough, corrugated; rind 
thick; color greenish; rag tough; juice scant, of poor quality and 
flavor; seeds averaging 2 or 3 per fruit; in fact, these fruits are not 
worth shipping to eastern markets, but in these investigations they 
have been included in the standard grade for this variety. This 
strain, however, is one of the most interesting in the variety for 
purposes of studying the behavior of bud mutations in citrus fruits. 
LONG STRAIN. 
The habit of growth and foliage characteristics of the Long strain 
are similar to those of the Valencia strain, but the trees are less 
productive. 
The fruits, as shown in Plate III, are cylindrical and much longer 
than those of other strains; size, as measured by cross diameter, 
small to medium; texture smooth; color bright orange; rag tender; 
juice abundant, sweet, of good quality; seeds averaging 1 or 2 per 
fruit. The peculiar shape of these fruits makes them unsuitable 
for packing and marketing under prevailing conditions. This strain 
frequently occurs as limb sports in trees of the Valencia strain. 
RIBBED STRAIN. 
The trees of the Ribbed strain are usually very irregular in produc- 
tion, bearing full crops some seasons, followed by several seasons of 
very light- production. The habit of growth is usually drooping, 
and the foliage is sparse, the leaves being small and sharply pointed. 
The typical fruits, as shown in Plate IV, are globular, sometimes 
somewhat flattened on both stem and blossom ends; size small; 
texture coarse; color pale yellow; rind thin to medium; rag tender; 
juice abundant, inferior in quality and flavor to that of the fruits of 
the Valencia strain; seeds averaging 2 per fruit. The ribbed char- 
acter of the rind gives the fruits a striking appearance, but it detracts 
from their commercial value under prevailing market conditions. 
YELLOW STRAIN. 
The productiveness of the trees of the Yellow strain is about the 
same as those of the Ribbed strain, except that they show a tendency 
to more regularity of annual production. The habit of growth is 
spreading and drooping. The foliage is of medium density, the 
leaves being medium in size and sharply pointed.
