HYBRID VARIETIES 
The following hybrids were developed by the Texas Agricultural 
Experiment Station, and have proven to be generally well adapted 
in the corn growing sections of the state. 
TEXAS WHITE HYBRID NO. 7 (w) 
An early to mid-season prolific and vigorous double cross hybrid that has 
proven to be an outstanding roasting ear variety of special merit. Parentage: 
(102A x 158-4) x (4R3 x 61M). Ears of medium size, very uniform in shape 
and grain character, with good husk coverage; kernels tight set, of medium size, 
not hard. Has proven well adapted to varying soil and seasonal conditions. 
120 days 
TEXAS WHITE HYBRID NO. 9 (w) 
Similar to No. 7 except for better husk coverage. A later development than 
No. 7, seed will not be available until 1945 crop harvest. Parentage: (102A x 
155A) x (4R3 x 61M). 
TEXAS YELLOW HYBRID NO. 8 (y) 
A very early double top cross hybrid with Yellow Surcropper as the seed parent 
and a single cross hybrid (127C x 132A) as the pollen parent. Probably not as 
uniform in ear and grain character as the other hybrids in this series, but is quite 
drought-resistant and has a high shellout percentage. Ears medium, slightly 
tapered; kernels yellow to reddish, somewhat hard; cob medium. Not the highest 
yielding hybrid variety but is widely adapted. 118 days 
TEXAS YELLOW HYBRID NO. 10 (y) 
A double top cross similar to No. 8, but later maturing, with larger ears, having 
more dent character and uniformly large golden yellow kernels, tight set on the 
cob. The seed parent is Yellow Surcropper and the pollen parent (132A x 173D). 
122 days 
TEXAS YELLOW HYBRID NO. 12 (y) 
One of the most dependable and popular double cross hybrids yet developed in 
Texas. The seed parent is hybrid (KYS x K4) and the pollen parent (127C x 
132A). It is noticeably uniform in ear and grain character and has proven better 
adapted to the good corn soils in the higher rainfall areas than elsewhere. Ears 
are medium long and cylindrical to slightly tapered; kernels of rich yellow color, 
hard, with dimple dent. 120 days 
TEXAS YELLOW HYBRID NO. 18 (y) 
The most recent double cross released by the Texas Experiment Station. The 
seed parent is hybrid (173D x 203) and the pollen parent (127C x 132A). This 
is the first all Texas yellow double cross so far developed, with all inbreds used 
in the hybrid originating from native yellow dent varieties. This hybrid 
produces rather large, slightly tapering ears, with large, soft, deep yellow kernels. 
The stalk is stout and strong, but the plants may root lodge under heavy 
winds. Results so far indicate this hybrid may be expected to give yields similar 
to those of No. 12. 120 days
