As shown in Table IX, Giant Winter, C. I. No. 30, is the leading 
variety in yield of those tested four years. The Abruzzes, C. I. 
No. 40, which has been grown only three years, is only slightly 
lower in yield than the Giant Winter for that period (fig. 4). The 
lowest average yield for the four years was obtained from the Ivanof, 
C. I. No. 34. The differences in yield are slight, however, and a test 
for a longer period may show a quite different ranking. 
According to the data in Table, IX, the period between heading 
and ripening in rye is about 6 weeks. This is about 2 weeks longer 
than in wheat. The average date of heading in the 12 varieties and 
selections has varied from April 28 to May 12 and the average time 
of ripening from June 16 to 27. The average height of the plants has 
been about 5 feet. The average yield of straw of those tested four 
years has varied from 2,990 to 4,350 pounds. The data on yield
