In summary, Eastman produced a small tree which yielded poorly. Other 

 strains produced trees of similar size and productivity. Marshall produced 

 fruit which colored earlier and to a higher degree and ripened earlier than 

 fruit from other strains. Fruit quality after storage was similar for all 

 strains in this study. Another Mcintosh strain trial was established in 1985 

 with a number of high-coloring strains, including Redmax. Results from this 

 study will be reported in future issues of Fruit Notes.
