latter being about equal to Winter Turf in hardiness and ranking 
next to it. Winter hardiness is an important factor in the adapta- 
bility of oat varieties at Arlington Farm. The lower yield of Red 
Rustproof is owing to lack of hardiness, resulting in reduced stands 
and yields. Of the three Red Rustproof strains now being grown at 
Arlington Farm, none is sufficiently winter hardy to warrant increase 
or distribution in the northern part of the winter-oat territory. 
Culred (C. I. No. 518-189), a variety belonging to the Avena byzan- 
tina group, with whitish kernels, has been even less promising. In 
nursery experiments this strain has produced very high yields, and 
the low yields obtained in field plots are difficult to explain.

Among the Fulghum strains only Fulghum (C. I. No. 708) has been 
grown for a period of sufficient length to determine relative values. 
This strain has produced better yields than the Red Rustproof 
strains, but not such good yields as the leading strains of the other
