It will be noticed that Early Ozark gave the highest yield per 
pot; Haverland second highest; Glen Mary third; Marshall 
fourth; Senator Dunlap fifth; Bubach sixth; William Belt 
seventh; Warfield eighth, and Aroma ninth. Eliminating the old 
plants of the Marshall and Glen Mary from the total number, 
Glen Mary is the highest yielder in weight and marketable fruit, 
followed by Marshall. While the Early Ozark gave a high yield, 
the fruit was small, soft and of, rather poor quality. The same 
was true of the Warfield. This variety bore the largest number 
of fruits, but the fruit is too small. Haverland gave a large yield, 
but the fruit was poorly colored and too soft for handling. 
Bubach gave a fine yield, but the fruit w r a.s somewhat irregular 
and not up to the standard. William Belt produces the largest 
berries, but this variety has a decided tendency to produce double 
fruit, and does not ripen evenly. Senator Dunlap produced fine 
fruit, but not of sufficient quantity. Aroma proved to be a very 
poor yielder, and gave the lowest results of all varieties. The old 
plants both of Marshall and Glen Mary produced small and in¬ 
ferior fruits. The vigor and general appearance of the plants were 
poor. 
CONCLUSIONS 
Marshall and Glen Mary proved to be the best two varieties 
for forcing in Colorado. The fruit produced is large, fine color, 
firm and of excellent quality. Marshall does not yield as heavily 
as the Glen Mary, but compensates for this deficiency by produc¬ 
ing an extra high quality of fruit. The chief reason for using 
Marshall in forcing is because of its ability to produce an abund¬ 
ance of pollen, while Glen Mary produces few, if any. 
New crowns are preferable to old ones, as they produce a 
heavier yield and larger and better berries.
