1 California strain.

3 Grown prior to 1911 as a spring variety. 



4 Not comparable because of abnormal soil conditions. 



5 Data for 2 years only. 



6 Data for 1 year onlv. 



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
