Rootstocks 



Trees on dwarfing rootstocks have been planted extensively 

 by Michigan apple growers in recent years. Nevertheless, clonal 

 rootstocks have not solved all of our apple production problems. 

 In fact they have introduced additional problems. 



Clonal rootstocks used initially were M.2 and M.7. M.2 tended 

 to be too vigorous and M.7 develops suckers from the rootstock and 

 gives poor anchorage to the more vigorous varieties, notably Deli- 

 cious. 



MM 106 and IM 111 were popular rootstocks when they became 

 available in the early 60's. MM 106 is a very productive and pre- 

 cocious rootstock but often produces a larger tree than antici- 

 pated, particularly with Mcintosh and Paulared varieties. It also 

 has been sensitive to cold injury and collar rot, particularly 

 when planted on poorly drained soils or on some of Michigan's heav- 

 ier textured soils. MM 111 has not been as dwarfing as desired 

 and has been slow to initiate bearing on young trees. 



M.9, popular for high density plantings, is not well adapted 

 to Michigan's light textured orchard soils. Trees on this root- 

 stock are readily stunted by drought and weed competition. The
