Data were recorded in 1921 and 1922 on the number of spikelets 
and the percentage of seed set on 90 to 100 heads of each of the two 
varieties, Rosen and Abruzzes. The data for the two years show 
that Rosen produces on the average 37.2 spikelets to the head as 
compared with 34.5 for Abruzzes. The latter variety set the higher 
percentage of seed in 1921 and Rosen in 1922. It is probable that 
this character is more dependent on external factors than on varietal 
differences. On the average about two-thirds of the flowers set seed. 
The quality of rye produced at the Arlington Experiment Farm, as 
judged by bushel weight (Table 14) , has been poor. Rosen is especially 
low in bushel weight, and Abruzzes (C. I. No. 40) is of much better 
quality. Lodging has reduced the bushel weight of the ryes. Table 
14 shows other agronomic data obtained on six varieties of winter rye.
