SWEET CORN 
Developments in the field of hybridization during the last twenty years have 
revolutionized the sweet corn seed industry. Asa result of hybrid introductions 
during that period, seedsmen are able to offer their customers sweet corn with 
grater uniformity of ear type, plant habit and maturity than that possessed by 
open-pollinated varieties formerly used. Greater disease resistance, increased 
yields, and improved eating and processing qualities are to be found in the better 
hybrids. 
Our sweet corn breeding and trials program is designed to maintain excellent 
strains of the generally accepted hybrid and open-pollinated types, as well as to 
develop and test new hybrids that will offer improvement in quality, yield, 
kernel character, ear type and plant habit. 
An intense inbreeding program is carried on to originate new inbred lines 
and hundreds of experimental hybrids are made annually for testing in our trial 
plots. Only a very small percentage of such new crosses tested survive the 
critical evaluation to which they are subjected, as it is our intention to introduce 
only those hybrids which show definite superiority over established types of 
sweet corn in Current usage. 
Carefully selected and maintained parent stocks are used in our program. 
All possible care is exercised to maintain inherent purity of this parental material 
in the crossing fields by observing definite rules governing optimum isolation, 
careful roguing, and thorough and timely detasseling. Frequent inspections 
made during the growing season give assurance that the best field production 
practices are being employed. 
In all processing steps, from field harvest through drying, shelling, cleaning 
and the final hand-picking, every precaution is taken to use the best techniques 
and machinery of the latest design to avoid mechanical injury and to produce 
seed of uniformly high vitality. 
We wish to express our sincere appreciation to the personnel of the several 
Colleges and Universities through whose efforts and hybrid introductions much 
of the progress in sweet corn improvement has been made.
