Endangered Maize by Helen Anne Curry Pdf

Charting the political, social, and environmental history of efforts to conserve crop diversity. Many people worry that we're losing genetic diversity in the foods we eat. Over the past century, crop varieties standardized for industrial agriculture have increasingly dominated farm fields. Concerned about what this transition means for the future of food, scientists, farmers, and eaters have sought to protect fruits, grains, and vegetables they consider endangered. They have organized high-tech genebanks and heritage seed swaps. They have combed fields for ancient landraces and sought farmers growing Indigenous varieties. Behind this widespread concern for the loss of plant diversity lies another extinction narrative that concerns the survival of farmers themselves, a story that is often obscured by urgent calls to collect and preserve. Endangered Maize draws on the rich history of corn in Mexico and the United States to uncover this hidden narrative and show how it shaped the conservation strategies adopted by scientists, states, and citizens. In Endangered Maize, historian Helen Anne Curry investigates more than a hundred years of agriculture and conservation practices to understand the tasks that farmers and researchers have considered essential to maintaining crop diversity. Through the contours of efforts to preserve diversity in one of the world's most important crops, Curry reveals how those who sought to protect native, traditional, and heritage crops forged their methods around the expectation that social, political, and economic transformations would eliminate diverse communities and cultures. In this fascinating study of how cultural narratives shape science, Curry argues for new understandings of endangerment and alternative strategies to protect and preserve crop diversity.

Maize by Duccio Bonavia Pdf

This book examines one of the thorniest problems of ancient American archaeology: the origins and domestication of maize. Using a variety of scientific techniques, Duccio Bonavia explores the development of maize, its adaptation to varying climates and its fundamental role in ancient American cultures. An appendix (by Alexander Grobman) provides the first-ever comprehensive compilation of maize genetic data, correlating this data with the archaeological evidence presented throughout the book. This book provides a unique interpretation of questions of dating and evolution, supported by extensive data, following the spread of maize from South to North America and eventually to Europe and beyond.

Maize and Grace by James C. McCann Pdf

Sometime around 1500 AD, an African farmer planted a maize seed imported from the New World. That act set in motion the remarkable saga of one of the world’s most influential crops—one that would transform the future of Africa and of the Atlantic world. Africa’s experience with maize is distinctive but also instructive from a global perspective: experts predict that by 2020 maize will become the world’s most cultivated crop. James C. McCann moves easily from the village level to the continental scale, from the medieval to the modern, as he explains the science of maize production and explores how the crop has imprinted itself on Africa’s agrarian and urban landscapes. Today, maize accounts for more than half the calories people consume in many African countries. During the twentieth century, a tidal wave of maize engulfed the continent, and supplanted Africa’s own historical grain crops—sorghum, millet, and rice. In the metamorphosis of maize from an exotic visitor into a quintessentially African crop, in its transformation from vegetable to grain, and from curiosity to staple, lies a revealing story of cultural adaptation. As it unfolds, we see how this sixteenth-century stranger has become indispensable to Africa’s fields, storehouses, and diets, and has embedded itself in Africa’s political, economic, and social relations. The recent spread of maize has been alarmingly fast, with implications largely overlooked by the media and policymakers. McCann’s compelling history offers insight into the profound influence of a single crop on African culture, health, technological innovation, and the future of the world’s food supply.

Mutants of Maize by M. Gerald Neuffer,Edward H. Coe,Susan R. Wessler Pdf

This unique work of reference provides quick and easy access to the remarkable diversity of mutant phenotypes expressed by the maize plant. Its major portion consists of over 400 color photographs of well-established mutants arranged by chromosome position, detailed descriptions of the mutants' gene loci, and a current summary of the physical structure of genes that have been characterized at the molecular level. First published in 1968 and long out of print, Mutants of Maizehas been entirely revised by three of the corn plant's most distinguished investigators, enlarged to cover twice the number of mutants, and redesigned with clarity and elegance. All maize biologists will want this magnificent book in their personal library. In addition, because mutant maize genes have counterparts in most species, the book can be considered a general guide to the consequences of mutation in the entire plant kingdom.

Maize Crop by A. Solaimalai,P. Anantharaju,S. Irulandi,M. Theradimani Pdf

Maize is one of the versatile emerging crops with wider adaptability under varied agro-climatic conditions. Globally, maize is known as queen of cereals because it has the highest genetic yield potential among the cereals. It is cultivated on nearly 150 m/ha in about 160 countries having wider diversity of soil, climate, biodiversity and management practices that contributes 36 % (782 m/t) in the global grain production. The United States of America (USA) is the largest producer of maize contributes nearly 35 % of the total production in the world. It is the driver of the US economy. This book talks about the improvement, production, protection and post harvest technology of the maize crop.

Midwest Maize by Cynthia Clampitt Pdf

Food historian Cynthia Clampitt pens the epic story of what happened when Mesoamerican farmers bred a nondescript grass into a staff of life so prolific, so protean, that it represents nothing less than one of humankind's greatest achievements. Blending history with expert reportage, she traces the disparate threads that have woven corn into the fabric of our diet, politics, economy, science, and cuisine. At the same time she explores its future as a source of energy and the foundation of seemingly limitless green technologies. The result is a bourbon-to-biofuels portrait of the astonishing plant that sustains the world.

Maize in India by Anonim Pdf

Maize is a promising substitute crop allowing diversification from the rice-wheat system in the upland areas of India. The crop has high production potential, pr ovided the available improved hybrids and composites reach the farming community. This study found that major biotic production constraints were Echinocloa, Cynodon dactylon, rats, and termites, which reduced maize production levels by more than 50%. Other important abiotic and biotic stresses listed in descending order of importance were: caterpillars, water stress, stem borers, weevils, zinc deficiency, rust, seed/seedling blight, cutworm, and leaf blight. Non-availability of improved seeds, inadequate input markets, inef fective technology dissemination, and lack of collective action were the principal socio-economic constraints.

The Maize Handbook by Michael Freeling,Virginia Walbot Pdf

The Maize Handbook represents the collective efforts of the maize research community to enumerate the key steps of standard procedures and to disseminate these protocols for the common good. Although the material in this volume is drawn from experience with maize, many of the procedures, protocols, and descriptions are applicable to other higher plants, particularly to other grasses. The power and resolution of experiments with maize depend on the wide range of specialized genetic techniques and marked stocks; these materials are available today as the culmination of nearly 100 years of genetic research. A major goal of this volume is to introduce this genetical legacy and to highlight current stock construction programs that will soon benefit our work, e. g. high-density RFLP maps, deletion stocks, etc. Both stock construction and maintenance are relatively straightforward in maize as a result of the ease of crossing and the longevity of stored seeds. Crossing is facilitated by the separate staminate (tassel) and pistillate (ear) flowers, a feature almost unique to maize. On the other hand, many of the genetic methodologies utilized with maize, including the precision of record keeping, can be adapted to other plants. Facile communication and a spirit of co-operation have characterized the maize genetics community since its earliest days. Starting in the 1930s, institutions such as annual Maize Genetics Cooperation Newsletter, the Maize Genetics Stock Center, and the annual maize genetics meeting provide continuity to the field.

Molecular Genetic Approaches to Maize Improvement by Alan L. Kriz,Brian A. Larkins Pdf

During the past decade, there has been tremendous progress in maize biotechnology. This volume provides an overview of our current knowledge of maize molecular genetics, how it is being used to improve the crop, and future possibilities for crop enhancement. Several chapters deal with genetically engineered traits that are currently, or soon will be, in commercial production. Technical approaches for introducing novel genes into the maize genome, the regeneration of plants from transformed cells, and the creation of transgenic lines for field production are covered. Further, the authors describe how molecular genetic techniques are being used to identify genes and characterize their function, and how these procedures are utilized to develop elite maize germplasm. Moreover, molecular biology and physiological studies of corn as a basis for the improvement of its nutritional and food-making properties are included. Finally, the growing use of corn as biomass for energy production is discussed.
