Figure 1. Cumulative fruit drop in 1994 and 1995 from Pioneer 

 Mac, Marshall Mcintosh, and Rogers Red Mcintosh. 



days earlier than the other strains, but there was 

 no difference between Pioneer and Rogers. 



Drop was counted under each tree weekly dur- 

 ing the harvest seasons of 1994 and 1995 (Figure 

 2). In 1994, fruit dropped earlier from Marshall 

 trees than the other two strains, but there were no 

 differences between Pioneer and Rogers. In 1995, 

 again Marshall trees lost fruit earliest. Rogers trees 

 lost them the latest, and Pioneer trees were inter- 

 mediate between the two. 



From these data, it appears that Pioneer Mac 

 does not have delayed ripening or drop compared 

 to the standard strain, Rogers Red Mcintosh. Does 

 this result mean that it does not have a place in the 

 industry? No, Pioneer is a good Mcintosh. It pro- 

 duces a healthy tree with good productivity. Fur- 

 ther, it colors well, possibly better than Rogers, and, 

 although it was not measured here, there is some 

 indication that it will produce a firmer fruit, possi- 

 bly resulting in better condition out of storage.
