Not one man in a thousand has accuracy of eye and judgment sufficient to become an eminent breeder. If gifted with these qualities, and he studies his subject for years, and devotes his lifetime to it with indomitable perseverance, he will succeed, and may make great improvements; if he wants any one of these qualities he will assuredly fail.
Charles Darwin, 1859. The Origin of Species.
Maize is the most important crop plant in the Western Hemisphere and among the the top three food plants world wide. In addition to its efficiency in providing energy to a hungry world it is unsurpassed in its versatility. Specific types of maize are popular as vegetables and snackfoods, while others have myriad industrial uses. Maize is an important organism for fundamental research, especially in the fields of genetics, cytogenetics, quantitative genetics, and molecular biology. Researchers in all these areas often need to know the pedigrees of the particular strains with which they are working. However, such information is scattered, fragmentary, and often inaccessible. Hybrid maize and the development of inbreds are relatively recent technologies. The maize breeders who developed first cycle inbreds and recall the widespread use of open-pollinated varieties have acted as historians. As that generation passes the need for a written record has become clear.
This compilation is an attempt to bring together available pedigree information and to provide references for each pedigree. Many of the pedigrees in this volume have been found by searching through Experiment Station bulletins, mimeos, and memoranda, minutes of regional maize breeding meetings, and other written documentation. Other pedigrees are from the records of plant breeders who were asked to review certain sections. Thus, some of the references will be inaccessible to many readers, but the inclusion of these provides a historical record. Given the nature of the literature search it is inevitable that some inbreds or populations have not been included, and we would like to hear from you if you have useful records for future revisions.
We thank all the maize breeders who took the time to edit and revise the relevant sections, in many cases the amount of effort contributed was substantial. We also wish to express our extreme gratitude to those, who over the years have, carefully compiled and recorded the pedigrees of maize germplasm, most especially Clarion Henderson of Illinois Foundation Seeds, Inc., Champaign, IL, and the authors of the Seedsman's Handbook at Mike Brayton Seeds, Inc., Ames, IA.
