FALL-SOWN OATS IN THE SOUTH 15 
slightly the highest yield of all Winter Turf strains grown in the nursery 
during the period from 1921 to 1925. 
The Culberson strains when grown in the nursery, as in the field 
plot experiments, were slightly below those of the Winter Turf group 
in yield. One of the Culberson strains (C. I. No. 273-41-203) is of 
particular interest, as the young plants are completely covered with 
short setaceous hairs. This strain seems to possess unusual cold 
resistance, but so far it has not shown high-yielding ability. The one 
~ Bicknell strain for which data are given has about equaled the best 
Culberson strains in yield. 
The Hatchett or black winter strains have produced yields in the 
nursery considerably higher than in field plots. As a group these 
strains have about equaled the Winter Turf strains in average yield. 
The black kernels of these strains are not desirable. 
The Red Rustproof strains in the nursery have fallen considerably 
below those of the three preceding varieties in yield, agreeing with 
the field-plot results. These strains yield less than the strains of 
other standard varieties when grown in either field or nursery, yet 
like the Hatchett strains their nursery yields have been inconsist- 
ently higher than in field plots. 
The two strains of Culred rank among the very highest yielders in 
the nursery. This oat differs from the Red Rustproof in having nar- 
rower leaves and amore spreading habit in early growth. The kernels 
of these two strains are a grayish white in color. Culred (Hybrid No. 
581 al—7-3) originated as a selection from a hybrid made about 20 
years ago between Red Rustproof and Culberson. The other strain 
(C. I. No. 518-189) was selected from Red Rustproof (C. I. No. 
518) in 1918. This strain is identical morphologically with Culred 
and probably resulted from natural hybridization. The grain qual- 
ity of these strains has been rather poor. Culred (C. I. No. 518- 
189) grown in field plots produced a very unsatisfactory yield, and 
its excellent nursery yield is difficult to explain. 
The original Fulghum strains (C. I. Nos. 708, 839, and 850) gave 
very high yields under nursery conditions. These strains produced 
average nursery yields exceeding those of the best Winter Turf 
strains during the three-year period from 1923 to 1925, inclusive. 
Under the nursery conditions prevailing at the Arlington Experiment 
Farm, the tender varieties seem to be more favored than when 
erown in plots under field conditions. This is indicated by the 
behavior of the Hatchett, Red Rustproof, and Fulghum strains. 
Promising strains of Fulghum have been isolated, as is shown by 
nursery yields during the years 1923 to 1925, inclusive. These selec- 
tions represent a distinct winter form of Fulghum. The young plants 
are a darker green in color and more prostrate in early growth habit, 
and most of the strains are a little later in maturity than the original 
Fulghum. There also is considerable variation in size of kernel. 
These winter forms of Fulghum appear promising as new fall-sown 
strains for the Fulghum oat area of the South. 
The identical varieties Aurora and Yellow Peruvian have not pro- 
duced high nursery yields. They have about equaled the Red Rust- 
proof strains. The Aurora type of oats is entirely too tender for 
best results from fall seeding. The variety Navarro (Ferguson 
Navarro, C. I. No. 966) was obtained from the Ferguson Seed Farms, 
Sherman, Tex., a few years ago. It is said to have originated as a
