 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, tlie average height and weight per 

 bushel, and the average yields of grain and of straw from each variety 

 during the seven years. From tliis table it will be seen that, as a

Durum wheat. — The leading durum wheat is the PeHssier (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. Tliey have glabrous yellow glumes and yeUow 

 awns. 



Common wheat. — ^Among the common wheats that have been tried, 

 the Galgalos (C. I. No. 2398) has produced the liighest 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 cpahty as compared with the hard 

 wheats. 



Of the Fife group, only two varieties have been grown durmg the 

 full period. Tliese are the Kystmg 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 j^ears. This
