SEASON OF RED RASPBERRY VARIETIES 



One of the important characteristics of any fruit variety is its season of 

 harvest, 



V/ith any fruit which ripens over an extended period the meaning of early, mid- 

 season or late is not readily apparent. 



In order to obtain a numerical expression of time of ripening for the variet- 

 ies under test vre have divided the entire picking season for all varieties into 

 thirds. Then for each variety the percentage of its crop harvested in the first 

 and last third of the season has been determined. This information is recorded 

 in the following table for the years 1953 through 1955 • 



Season of Harvest - 1953-1955. 



The summer crops only of September and Durham are represented in the figures 

 for the two everbearers. The severity of winter injury on Willamette, Viking and 

 Amber in 1955 may have delayed their season of ripening for that year. 



During the period 1953-55 Gatineau, September, Madawaska, Latham and possibly 

 Milton have been the most dependable varieties under trial, Tweed and Antietam 

 have been discarded because of their small and poor quality fruit, Durham cannot 

 compete with other varieties in the early summer season, yet it is the earliest in 

 fall crop, Willamette has an excellent fruit but winter killing makes it unreliable 

 for any but the gambler.
