the thickness of the rind is usually somewhat greater than that of 
normal Valencia oranges. The typical fruits of several other strains, 
including the Dwarf, Willow-Leaf, Corrugated, and Unproductive, 
are also very coarse, but in those cases this characteristic is cor- 
related with shape, size, quality, or other character of the oranges, 
which is not the case with the typical fruits of the Coarse strain. 
The performance records of five progeny trees propagated from 
three Coarse strain limb variations in Valencia trees otherwise 
normal are shown in Table 11, and fruits from one of them are 
Fig. 13. — Fruits of the Coarse (left) and Valencia (light) orange strains. These were 
produced by progeny tree No. 12-9, as listed in Table 11, which was propagated from 
an unstable limb variation of the Coarse strain. Riverside, Calif., January, 1926.

shown in Figure 13. It will be noted that all of the progeny trees 
have produced both typical Coarse and Valencia strain fruits each 
season. The proportion of coarse to normal fruits has been fairly 
equally divided in the crops of the progeny trees, as was the case 
in the crops from the parent limbs. The crops of three of the Coarse- 
strain progeny trees have been smaller than those from comparable 
progeny trees in the same planting which were propagated from 
normal limbs in trees of the Valencia strain. The production has 
been about equal to progeny trees of the Valencia strain, and the 
character of the tree growth and habit of fruiting of these trees thus
