446 THE APPLE 



Heredity and variation as affecting color. The environmental 

 factors influencing the color of apples have been discussed, but 

 other influences must be considered. The influence of internal 

 factors is obvious in such varieties as the Yellow Transparent, Yellow 

 Newtown, and Rhode Island Greening, or in other varieties, as the 

 Jonathan, Mcintosh, and Baldwin. The difference in color in these 

 varieties doubtless comes from variations in the seed. There is 

 evidence, however, that at least some of the differences are due to

 What is more inviting or more pleasing than a plate of extra-choice apples ? 



variations in buds or branches — even on the same tree. This is 

 true of the Banks and Collamer apples, which have been devel- 

 oped from the Gravenstein and Twenty Ounce varieties, respec- 

 tively, by variations in single branches of their parent trees. The 

 narrow red stripes of the parent apples have been broadened so as 

 to cover the fruit much more completely. In two other cases these 

 stripes are further broadened into practically solid-red colors. These 

 are the Hitchings, and the Red Gravenstein reported by Beach 

 from an island in Puget Sound. The origin of Gano which has 

 been obtained from the Ben Davis may also be a case emphasiz- 

 ing the particular fruit.
