BUD VARIATION IN THE VALENCIA OEANGE. 



109 



Section B of Table IV shows the groups of trees of the different 

 strains ranked according to the average annual crop of first, or 

 Orchard, grade fruit produced. This change alters the relative 

 position of several of the strains, but the Valencia strain is still at 

 the head and the Barren strain at the foot of the list.

 orange occurring in the investigational performance-record plat, showing production by 

 commercial grades for the 4-year period, 1912 to 1915, inclusive.

It should be noted that the 10 highest producing trees of the 

 Valencia strain are also the 10 highest producing trees in the plat, 

 irrespective of strain. Table I shows that the highest producing 

 tree of a strain other than the Valencia is twenty-eighth in rank. 



Figure 2 shows graphically the percentages of Orchard, Standard, 

 and Cull grade fruits in the average annual production of groups of 

 trees of the various strains represented in the investigational per- 

 formance-record plat. This diagram can best be interpreted by com- 

 paring it with Table IV, which shows the actual average crops of 

 these groups of trees of the different strains. Although the trees of 

 the Smooth strain head the list in figure 2, their actual average pro- 

 duction was only 60.6 pounds of Orchard-grade fruit, with a total 

 production of 75.8 pounds, so that in value to the grower they are
