NORTHRUP, KING & CO'S DEPENDABLE STERLING SEED CORN 
Varieties of Sterling Seed Corn 
(Open Pollinated, continued) 
90 Day Group 
STANDARD NORTHWESTERN RED DENT 
90 Day 
The original stock of this variety came into the Northwest from 
Indiana in an early day. Northwestern is called a red semi-dent being a 
cross between a red flint and a yellow dent. It is about 10 days earlier 
than Minn. No. 13 and adapted to northern Wisconsin and Minnesota and 
to North Dakota and similar areas. Ears carry 10 to 14 rows and are quite 
tapering. Kernels are red with a copper yellow cap. They are quite broad 
and shallow. Stalk height is about 3 /o to 1 ft. shorter than Minn. No. 13 
and suckers are general. Ears are borne quite low. Northwestern seems 
to have the same characteristics as Flint in being able to make more 
progress in cool weather than Dents. 
EXTRA EARLY MINN. NO. 13 HANEY STRAIN 
90 Day 
This strain came from an early selection of Standard No. 13 made by 
Mr. Thorpe of Mayville, North Dakota, beginning immediately after the 
introduction of Standard Minn. No. 13 in 1897. When J. G. Haney estab¬ 
lished the International Harvester Co.’s Experiment farm at Grand Forks, 
North Dakota, he secured this Thorpe Strain and continued selection and 
breeding. Haney Strain was introduced as such by Northrup, King & Co., 
in 1921. It is adapted to N. W. Minnesota, North Dakota and similar areas. 
General ear characters are the same as Standard Minn. No. 13 except 
smaller. Stalk height is from i/2 to 1 ft. shorter. Maturity about 10 days 
earlier than Standard Minn. No. 13. 
EXTRA EARLY RUSTLER, WHITE DENT, PAYNES STRAIN 
90 Day 
This strain came from Western South Dakota. It is about a week 
earlier than Standard Rustler. Stalk height is about 1/2 to 1 ft. shorter 
than Standard and is adapted to the same areas as Haney Strain Minn. 
No. 13. Ears carry mostly 12 rows ranging from 10 to 16 rows. Kernels 
are shallow and wide. 
RAINBOW MIXED COLORED FLINT 
90 Dav 
A 10 to 16 row flint with kernels colored all colors of the Rainbow. 
Matures about the same time as Haney Strain but stalk growth is taller 
with many long suckers. This variety probably originated in Southern 
South Dakota, but our Sterling Strain is an earlier strain than the South 
Dakota Strain and matures quitely nicely in North Dakota. Adapted to 
northern and central Wisconsin, northern and central Minnesota and North 
Dakota and Montana. This is our most popular flint variety because of 
its high yield of both grain and fodder. It seems consistently to outyield 
other flints of the same earliness. Do not confuse this variety with the 
native North Dakota Squaw Flint which is an extremely dwarf variety 
also with ears colored like Rainbow.
