FALL-SOWN OATS IN THE SOUTH 19 
Most of the varieties grown in these experiments were pure-line 
selections. These were developed by selecting several hundred 
panicles from each variety. The seed from every head or panicle 
was sown in a separate row and threshed separately. The poorer 
strains were gradually eliminated from year to year in nursery tests 
until only the selection giving the highest average yield remained. 
This was multiplied and used for general seeding. 
At the Georgia State College of Agriculture the Hasting (Hundred 
Bushel) strain of Red Rustproof, which originated as a selection from 
Appier, another strain of Red Rustproof, gave the highest yield, with 
Bancroft a close second. (Table6.) These were followed in order by 
Fulghum, Coker Appler, Appler, and Texas Red Rustproof—all 
except Fulghum being strains of Red Rustproof. 
The Fulghum variety, while producing the third highest average 
yield, is more subject to seasonal variations than Appler, for instance. 
Fulghum produces very high yields in favorable years, but drops low 
in unfavorable years. The variety is extremely susceptible to leaf 
rust, which often reduces the yield. Burt and Early Ripe are not 
sufficiently hardy for successful culture from fall seeding even in the 
South. Such varieties as Culberson, Hatchett, and Winter Turf are 
not well adapted to conditions in Georgia. The Lee and Custis 
varieties have produced fair yields during the two years they have 
been grown, but because of their winter hardiness these varieties are 
ooo better adapted to the extreme northern part of the Cotton 
elt.

‘Many growers find it profitable when fairly large acreages are 
srown to sow Red Rustproof on part of the area and Fulghum on the 
remainder. The Fulghum ripens from 7 to 14 days earlier than the 
Red Rustproof. This simplifies the harvesting problem by dis- 
tributing the optimum time for cutting over a longer period. A field 
of Red Rustproof oats near Columbia, S. C., is shown in Figure 8. 
In the experiments at the Coastal Plain Experiment Station, 
Tifton, Ga., the Red Rustproof strains, Hasting (Hundred Bushel), 
Appler, Coker Appler, Bancroft, and Patterson, have all given 
_ slightly higher yields than Fulghum and appear to be somewhat better
