BUD VARIATION IN THE VALENCIA ORANGE. \) 



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.
