Committee established a trial including 17 rootstocks 

 with Gala as the scion cultivar at 25 locations. Six of 

 the rootstocks were different strains of M.9. In this 

 article, we report the results gathered from one 

 location after 10 years of trial, concentrating on the 

 M.9 strains. 



M.26 EMLA and 

 M.27 EMLA are in- 

 cluded in this article 

 for comparison (they 

 also were part of this 

 trial). Trees were 

 planted in April of 

 1 994 at the University 

 of Massachusetts Cold 

 Spring Orchard Re- 

 search & Education 

 Center in 



Belchertown. MA in a 

 randomized-com- 

 plete-block design 

 with 10 replications. 

 All trees were staked 

 and maintained 

 roughly as vertical 

 axes. Pest and fertil- 

 ity management was 

 per local recommen- 

 dations. Root suckers were counted and cut annually. 

 Yield per tree and fruit size were assessed each year 

 from I99»6 to 2003. Trunk cross-sectional area (20" 

 abo\ e the graft union), canopy spread, and tree height 

 were measured at the end of the 2003 growing season. 



Materials 

 & Met hods 



Gala trees were 

 budded on various 

 rootstocks during 1992 

 growing season and 

 grown in the nursery 

 through the 1993 sea- 

 son. Trees were dug in 

 the fall, stored, and 

 shipped to cooperators 

 in the Spring of 1994.
