Book Description
Excerpt from Funk Farms, Birthplace of Commercial Hybrid Corn: A History of Hybrid Corn At the opening of the twentieth century attention of corn breeders was focused on ear type. In this heyday of what he contemptuously called the ten pretty ears, Mr. Funk was not only the largest commercial seed corn grower but the lead ing critic of contemporary corn selection methods. Mr. Funk early recognized that appearance of an ear of corn was no guarantee of its seed value. Funk Brothers maintained a large exhibit at the St. Louis Louisiana Exposition in 1904 to demon strate that the popular show type of corn was not sound from the farmer's standpoint. With James Reid (developer of Reid's Yellow Dent) Mr. Funk set himself squarely against the then-popular rough starchy corn of late maturity, low vitality and inferior root development that was taking the blue ribbons at corn shows. The result was develop ment of Funk's Utility Type Corn smoother, medium dent, faster growth, firmer and more solid ears. Another decade was to pass before farmers generally, following the lead of experiment stations and farm bureaus, endorsed the utility ear. Meanwhile Gene Funk had gone on to newer fields. He abandoned ordinary ear selection entirely to develop on a commercial scale a new system of corn improvement. For, in disapproving the value of the Ten Pretty Ears, Mr. Funk repudiated the whole principle of selection simply from either the ear or plant. The trouble with seed selection, he found, was that while the ear itself came from a good plant and carried desirable characters it would not reproduce those characters unless fertilized by pollen from equally desirable plants.

Book Description
Maize is one of the world’s highest value crops, with a multibillion dollar annual contribution to agriculture. The great adaptability and high yields available for maize as a food, feed and forage crop have led to its current production on over 140 million hectares worldwide, with acreage continuing to grow at the expense of other crops. In terms of tons of cereal grain produced worldwide, maize has been number one for many years. Moreover, maize is expanding its contribution to non-food uses, including as a major source of ethanol as a fuel additive or fuel alternative in the US. In addition, maize has been at the center of the transgenic plant controversy, serving as the first food crop with released transgenic varieties. By 2008, maize will have its genome sequence released, providing the sequence of the first average-size plant genome (the four plant genomes that are now sequenced come from unusually tiny genomes) and of the most complex genome sequenced from any organism. Among plant science researchers, maize has the second largest and most productive research community, trailing only the Arabidopsis community in scale and significance. At the applied research and commercial improvement levels, maize has no peers in agriculture, and consists of thousands of contributors worthwhile. A comprehensive book on the biology of maize has not been published. The "Handbook of Maize: the Genetics and Genomics" center on the past, present and future of maize as a model for plant science research and crop improvement. The books include brief, focused chapters from the foremost maize experts and feature a succinct collection of informative images representing the maize germplasm collection.

Book Description
Woven throughout the colorful history of corn production are multitudes of individuals – farmers, mechanical inventors, scientists, etc. – who have created the deep and fascinating fabric of corn history. In a special 1992 edition, TIME Magazine described corn hybridization as “one of mankind's greatest achievements in the last 1,000 years.”“Kernels of Corn History,” authored by fifth-generation Iowa farmer Steve Kenkel and South Dakota author/publisher Loretta Sorensen, brings together the story of 18 Iowa hybrid seed corn companies and detailed information about development of early corn farming implements those farmers used. The book also contains a pictorial tour of Kenkel's one-of-a-kind corn museum which grew out of his research efforts. The book is the outgrowth of 10 years of work Kenkel began in 2003 with a search for information about Iowa's Shelby County hybrid seed corn companies.Readers will enjoy a snapshot of the history of some innovative farmers and equipment manufacturers who have helped create the captivating history of growing corn in America.

Book Description
This volume explores problems in the history of science at the intersection of life sciences and agriculture, from the mid-eighteenth to the mid-twentieth century. Taking a comparative national perspective, the book examines agricultural practices in a broad sense, including the practices and disciplines devoted to land management, forestry, soil science, and the improvement and management of crops and livestock. The life sciences considered include genetics, microbiology, ecology, entomology, forestry, and deal with US, European, Russian, Japanese, Indonesian, Chinese contexts. The book shows that the investigation of the border zone of life sciences and agriculture raises many interesting questions about how science develops. In particular it challenges one to re-examine and take seriously the intimate connection between scientific development and the practical goals of managing and improving – perhaps even recreating – the living world to serve human ends. Without close attention to this zone it is not possible to understand the emergence of new disciplines and transformation of old disciplines, to evaluate the role and impact of such major figures of science as Humboldt and Mendel, or to appreciate how much of the history of modern biology has been driven by national ambitions and imperialist expansion in competition with rival nations.
