Uses Code 
ILLINOIS HULLESS (White) CIPNO 
Prof. B. L. Weaver, University of Illinois, originated this Japanese Hulless type which 
seems to mature practically free from smut. Particularly desirable for its high ratio 
of popping volume. 
EARS—Somewhat longer and slightly more slender than Japanese Hulless. 
JAPANESE HULLESS (White) or Australian Hulless CIPFA 
A white, small and slender pointed kernelled type, with short stubby ears about 
3!/ inches in length. Numerous irregular rows to zigzag kernel formation on cob. 
It is unusually tender, sweet and pure white when popped. Stalk slender and about 
5 feet tall. 
MINHYBRID 250 (White Hulless) CIHYB 
This white hybrid popcorn developed by Minn. Agric. Expt. Sta. is an improvement 
over Japanese Hulless for yield and popping expansion. It also matures earlier, prac- 
tically free from smut. Adapted to Northern areas. 
EARS—3 to 4 inches long, plump and blunt. 
PURDUE 32 or K4 (Yellow Hybrid) CIPKI 
A new development by Kansas State College and Purdue University. This is a yellow 
three-way cross hybrid to be used for the production of popping corn only. Extremely 
heavy yielding, kernels expand to exceptionally large size. The popped corn is desir- 
able for its tender texture and rich flavor. The plant growth is vigorous with a stalk 
approximately 6 ft. tall. The performance of this variety has been very satisfactory 
in the Central Western section. 
EARS—6 to 7 inches long, slightly tapered and well filled. This is mostly a 2 eared 
variety. 
SOUTH AMERICAN or T.N.T. or Dynamite (Yellow) CEPPO 
The most popular, widely adapted variety in the longer growing season areas. A large 
kernelled, dark yellow, pearl smooth kernelled type which is very productive of long 
slender 7 to 7!/> inch ears with 12 to 16 straight rows. A large dark green stalk about 
7\/ feet tall. Particularly desirable for its high yield of shelled corn per acre. 
When popped it has a buttered like, creamy appearance and expands to exceptionally 
large size. 
SUNBURST (Yellow) or Supergold CIYOM 
This is an early yellow variety with ears slightly smaller than those of South American. 
It has a fine creamy appearance and is sweet and tender when popped.
