Leading Varieties op Spring Wheat. 
Of the 25 varieties of spring wheat that are listed in Table XV 
only 9 have been grown during the entire period. Of these, 5 belong 
to the durum group, 2 to the Fife group, 1 to the Preston group, and 
1 is a miscellaneous variety. Table XVI gives the average dates of 
seeding, heading, and maturity, the average height and weight per 
bushel, and the average yields of grain and of straw from each variety 
during the seven years. From this table it will be seen that, as a 
group, the durum varieties yield higher than the other groups.

Durum wheat. — The leading durum wheat is the Pelissier (C. I. 
No. 1584). This variety has white glabrous glumes and black awns. 
The kernels are large, hard, and of a clear amber color. The other 
durum varieties that have been grown at Moccasin belong to the 
Kubanka group. They have glabrous yellow glumes and yellow 
awns. 
Common wheat. — Among the common wheats that have been tried, 
the Galgalos (C. I. No. 2398) has produced the highest 7-year aver- 
age yield. This variety is beardless, with brown pubescent glumes 
and rather large soft white kernels. While it yields well it is consid- 
ered by millers to be poor in quality as compared with the hard 
wheats. 
Of the Fife group, only two varieties have been grown during the 
full period. These are the Rysting and Ghirka. The Ghirka ripens 
about the same time as the durum varieties, while the Rysting is 
somewhat later. These two varieties have yielded from 3 to 4 
bushels less than the durum wheats. 
The Fretes (C. I. No. 1596) is the only variety belonging to the 
Preston group that has been grown during the seven years. This
