In the beardless common wheats there were 18 smooth-glumed and 
12 hairy-glumed races. As in the durums, the smooth-glumed races 
(mostly fifes) produced more grain, longer heads, and fewer tillers per 
plant than the pubescent-glumed ones (mostly bluestems). The 
smooth-glumed races also had shorter and lighter straw, more heads — 
per plant, and greater kernel weight than the hairy-glumed races. 
In the field plats the fife (glabrous glumes) and the bluestem (pubes- 
cent glumes) groups gave similar results in a 6-year average. The 
fifes had shorter straw and heavier yields of grain, with Beate! 
bushel weight, than wheats of the bluestem group. 
WINTER WHEAT. 
Winter wheat has been tried at Williston for six years, but the re- 
sults so far obtained are not favorable. Winter wheat can not be 
grown here successfully, at least not until some hardier varieties are 
secured. In 1909, 1910, and 1912 the winter-wheat varieties were on 
ground that Bhi was newly broken or had been fallowed. The 
other years they were in corn stubble, the cornstalks having been left 
standing during the winter. 
In the first case the varieties had no protection during the winter 
except the covering of snow that the plants themselves held, and win- 
terkilling was severe in all three years, with a total loss in 1912. For 
the three years that the wheat was sown in the standing cornstalks, 
the spring survival was much higher. Table XI shows the annual 
and average yields of seven varieties of winter wheat grown during 
the six years from 1909 to 1914, inclusive.

1 The 1912 crop was entirely winterkilled. 
The Beloglina (C. I. No. 1543) and an unnamed variety known as 
North Dakota No. 1997 (C. I. No. 3084) have been found to be the 
hardiest and best yielding varieties at Williston for the entire period. 
Both these varieties are of the Crimean or Turkey group of hard red
