EXPERIMENTAL FARMS 



7 GEORGE V, A. I9l7 



Horticulturist, Mr. W. T. Macoun, and from these, several very proraising types have 

 been secured. This work is being further carried on and enlarged, so that it is hoped 

 ultimately a series of varieties may be produced that can be grov?n successfully 

 despite severe winter conditions in many of the more northerly areas. 



During the past season a number of crosses were made with apple varieties, as 

 follows : —

(N.B. — The letter F. denotes the female parent, or tree upon which the fruit was 

 produced, and M. the male parent, or tree from which the pollen was secured.) 



During the past season an effort was made to ascertain to what extent varieties 

 of apples in the orchards at the Central Experimental Farm might be considered self- 

 fertile. With this object in view a number of varieties were pollinated with their own 

 pollen, and the flowers were enclosed in bags. In some instances these flowers were 

 emasculated and then pollinated by hand; in others the flowers were 

 merely enclosed in bags, being periodically shaken, with the object of covering the 

 pistils of these flowers with their own pollen. The following is a table giving the 

 results of this work. Three counts were made of the number of fruits set; the first 

 about three weeks after flowering, the second early in August and the third at the 

 time of harvesting.
