Coker’s Pedigreed 
COKER 
47-27 WHEAT 
1951 BREEDER’S REGISTERED SEED 
Coker 47-27, a new wheat variety first offered 
in 1950, was developed in our breeding nurseries 
from a cross between Fronteira and Hardired. Fron- 
teira, a spring wheat introduced by the U.S.D.A. 
Cereals Division, carries high resistance to leaf rust, 
many races of stem rust, and some degree of resis- 
tance to mildew. The Hardired parent contributed 
an adequate degree of cold hardiness for most sec- 
tions of the South. 
Coker 47-27 is a vigorous, stiff-strawed wheat 
maturing about midseason. In height it is slightly 
taller than Hardired, but owing to better straw, 
is more storm resistant, and is an excellent combine 
type. Being slightly later than Redhart, there is less 
likelihood of damage from frost occurring after 
heading. 
In productivity, Coker 47-27 has been outstanding. 
Two-year average results on co-operative tests con- 
ducted at 21 stations in 1949 and 19 stations in 1950 
located in 10 Southern states show that Coker 47-27 
was the highest yielding variety commercially avail- 
able. In 11 of the 21 tests in 1949, Coker 47-27 pro- 
duced yields higher than either of its 2 principal 
competitors. Similarly, in 10 of the 19 tests in 1950, 
Coker 47-27 yielded better than either of those 2 
varieties. The average yield of Coker 47-27 in the 
total of 40 tests was 23.6 bushels per acre. 
The yield data reported above indicate that Coker 
47-27 is very widely adapted throughout the South- 
ern wheat region. However, owing to the more 
severe winters at the higher elevations of the Pied- 
mont and mountain areas, we recommend that its 
sowing be confined to the middle and lower Piedmont 
and throughout the coastal plain. 
DESCRIPTION 
Plant: Semi-winter habit; good stooling; leafy, vigorous 
early growth; slightly taller than Redhart. 
Straw: Yellow, stiff, storm resistant. 
Heads: Erect, square, broad to the tip, with fully filled mesh 
and closely fitting straw-colored glumes. 
Yield: Very satisfactory. 
Disease resistance: Relatively tolerant, but not resistant to 
mildew. Excellent resistance to leaf rust and to the 
races of stem rust prevalent in the Southeast. 
Season: About two days later than Hardired; one week earlier 
than Fuleaster and Vahart. 
Grains: Plump, horny, with high gluten content; excellent 
in milling quality. 
OUT OF STOCK AND NOT AVAILABLE FOR 
1951 PLANTING SEASON. WILL BE OFFERED 
FOR 1952 PLANTING. 
LEFT: Photo on left shows stiff, storm-resistant straw, well-filled, erect 
heads of Coker 47-27 wheat. This variety has excellent resistance to leaf 
rust, is tolerant to mildew, and is making excellent yields in many parts 
of the southern wheat belt.
