Apple Clone Series" from Michigan State Uni- 

 versity, and the "Cornell-Geneva (or Geneva) 

 Series" from the New York State Agricultural 

 Experiment Station. In 1984, a trial of a num- 

 ber of these new rootstocks was planted at 

 approximately 30 locations throughout the 

 United States and Csmada. One of the plantings 

 is at the University of Massachusetts Horticul- 

 tural Research Center in Belchertown, Mass. 

 This article will report the results from this 

 planting through its ninth growing season. 



In April 1984, Starkspur Supreme Delicious 

 trees on Bud.9, MAC-1, MAC-39, P.l, P.22, 

 seedling, M.4, M.7 EMLA, M.26 EMLA, 



Bud.490, P.2, P.16, P.18, C.6, or Ant.313 were 

 planted in a randomized complete block design 

 with 10 replications. The soil is a Montauk fine 

 sandy loam. Mcintosh and Golden Delicious 

 trees were included in each rephcation for polli- 

 nation. All trees were trained as central leaders 

 and supp>orted by a post only when they leaned 

 more than 45° from vertical. All trees received 

 the same fertilizer apphcations, pest control 

 treatments, and chemical thinning sprays. 



Table 1 reports the trunk cross-sectional 

 area, yield, jdeld efficiency, and crop load of 

 these trees. MAC-1, seedling, Bud.490, P.18, 

 and Ant.313 produced trees of standard size.
