planted with Delicious and expect a good commercial crop on both varieties. 

 Other varieties that prove satisfactory when planted alone with Cortland 

 are Mcintosh, Northern Spy and W^ealthy. 



Delicious may be interplanted with any one of the following varieties and 

 both will set a good crop : Cortland, Oldenburg, Wealthy, Yellow Trans- 

 parent. 



Similarly Early Mcintosh and Wealthy are inter-fruitful, as are Fam- 

 euse and Mcintosh, and Gravenstein and Wagener. 



Mcintosh is inter-fruitful with each of the following varieties : Cortland, 

 Fameuse, Oldenburg, Wealthy, Yellow Transparent. 



Milton is inter fruitful with Wealthy. 



Northern Spy is interfruitful with Cortland, Golden Delicious, Olden- 

 burg and Wealthy. 



Wagener is inter-fruitful with Delicious and Gravenstein. 



Oldenburg is inter-fruitful with Delicious, Mcintosh, Northern Spy and 

 Wealthy. 



W^ealthy is inter-fruitful with Cortland, Delicious, Early Mcintosh, 

 Mcintosh, Milton, Northern Spy and Oldenburg. 



Yellow Transparent is inter- fruitful with Delicious and Mcintosh. 



On the other hand, in some combinations, two varieties may be planted 

 together and neither can successfully pollenize the other. Naturally such 

 combinations should be avoided unless other varieties are planted as pollen- 

 izers. They include the following : Baldwin and Rhode Island Greening or 

 Gravenstein ; Cortland and Gravenstein ; Delicious and Rhode Island 

 Greening ; Gravenstein and Baldwin or Cortland ; Mcintosh and Rhode 

 Island Greening; Northern Spy and Rhode Island Greening; Rhode Island 

 Greening and Baldwin, Delicious. Mcintosh, Northern Spy or Wealthy; 

 Wealthy and Rhode Island Greening. 



From this list the following combmations would be recommended where 

 desirable, because of coincidence of time of bloom and superior commercial 

 quality : 



Cortland and Delicious 

 Cortland and Wealthy 

 Delicious and Wagener 

 Delicious and Wealthy 

 Gravenstein and Wagener 

 Mcintosh and Cortland 

 Mcintosh and Wealthy 

 Northern Spy and Wealthy 



Often the choice of varieties is such that a third or occasionally even four 

 or more varieties need to be inter-planted to satisfy all needs for pollina- 

 tion. As an example of the latter, if Gravenstein, Baldwin, Delicious and 

 Mcintosh were the varieties to be planted in the orchard, all except De- 

 licious would be properly taken care of as far as pollenizers are concerned. 

 To insure a full set on Delicious, some other variety, such as Cortland, 

 Wagener or Wealthy, would also have to be planted in the orchard. 



If Rhode Island Greening, Gravenstein, Baldwin and Delicious were the 

 varieties desired for the commercial crop, it would be necessary to intro- 

 duce pollenizers for Delicious and Rhode Island Greening. Cortland is the
