Breeding Field Crops


Book Description

While preparing the first edition of this textbook I attended an extension short course on writing agricultural publications. The message I remember was "select your audience and write to it. " There has never been any doubt about the audience for which this textbook was written, the introductory course in crop breeding. In addition, it has become a widely used reference for the graduate plant-breeding student and the practicing plant breeder. In its prepa ration, particular attention has been given to advances in plant-breeding theo ry and their utility in plant-breeding practice. The blend of the theoretical with the practical has set this book apart from other plant-breeding textbooks. The basic structure and the objectives of the earlier editions remain un changed. These objectives are (1) to review essential features of plant re production, Mendelian genetic principles, and related genetic developments applicable in plant-breeding practice; (2) to describe and evaluate established and new plant-breeding procedures and techniques, and (3) to discuss plant breeding objectives with emphasis on the importance of proper choice of objec tive for achieving success in variety development. Because plant-breeding activities are normally organized around specific crops, there are chapters describing breeding procedures and objectives for the major crop plants; the crops were chosen for their economic importance or diversity in breeding sys tems. These chapters provide a broad overview of the kinds of problems with which the breeder must cope.




Religion, Politics, and Sugar


Book Description

Mary Lois Walker Morris was a Mormon woman who challenged both American ideas about marriage and the U.S. legal system. Before the Manifesto provides a glimpse into her world as the polygamous wife of a prominent Salt Lake City businessman, during a time of great transition in Utah. This account of her life as a convert, milliner, active community member, mother, and wife begins in England, where her family joined the Mormon church, details her journey across the plains, and describes life in Utah in the 1880s. Her experiences were unusual as, following her first husband's deathbed request, she married his brother as a plural wife in the Old Testament tradition of levirate marriage. Mary Morris's memoir frames her 1879 to 1887 diary with both reflections on earlier years and passages that parallel entries in the day book, giving readers a better understanding of how she retrospectively saw her life. The thoroughly annotated diary offers the daily experience of a woman who kept a largely self-sufficient household, had a wide social network, ran her own business, wrote poetry, and was intellectually curious. The years of "the Raid" (federal prosecution of polygamists) led Mary and Elias Morris to hide their marriage on "the underground," and her to perjury during Elias's trial for unlawful cohabitation. The book ends with Mary Lois's arrival at the Salt Lake Depot after three years in exile in Mexico with a polygamist colony.




Theory of Vibrating Lifting Tools of Sugar Beet Harvesters


Book Description

The cultivation and harvesting of sugar beets (roots and haulm) is one of the most labour and energy consuming work processes in the agricultural industry. The improvement of the qualitative indicators of the sugar beet harvesting process as the final operation in the work flow of its production represents a multi-faceted research-and-engineering problem, which is to be solved basing on the search for new implement design concepts and overall beet harvester design layouts, the thorough theoretical substantiation of their design and process parameters, the experimental verification of the completed theoretical research with the ultimate objective of the analysis and synthesis of their rational parameters. Theoretical research must play a fundamental role in the mechanical and technological substantiation of the root lifting process. It must be used as the basis for developing rational kinematic and dynamic operation conditions in order to achieve the required quality of the performed work process as well as the streamlined energy consumption. The book can be considered as one of the first solid analytical studies of the process of vibrational digging of sugar beet roots. It offers the analysis of up-to-date engineering solutions of vibrational digging tools and experimental investigations of the first vibrational lifters, the equation of oscillating motions of digging shares.










Metabolomics in Food and Nutrition


Book Description

Metabolomics enables valuable information about the biochemical composition of foods to be rapidly obtained. Since the biochemical profile of food largely determines key food properties such as flavour and shelf life, the information gained using metabolomics-based methods will enable greater control of food quality and also help to determine the relationship between diet and health. Metabolomics in food and nutrition provides an overview of their current and potential use in the food industry. Part one reviews equipment, methods and data interpretation in metabolomics including the use of nuclear magnetic resonance (NMR), statistical methods in metabolomics, and metabolic reconstruction databases and their application to metabolomics research. Part two explores applications of metabolomics in humans, plants and food. Chapters discuss metabolomics in nutrition, human samples for health assessments, and current methods for the analysis of human milk oligosaccharides (HMOs) and their novel applications. Further chapters highlight metabolomic analysis of plants and crops, metabolomics for the safety assessment of genetically modified (GM) crops, and applications of metabolomics in food science including food composition and quality, sensory and nutritional attributes. With its distinguished editors and team of expert contributors, Metabolomics in food and nutrition is a technical resource for industrial researchers in the food and nutrition sectors interested in the potential of metabolomics methods and academics and postgraduate students working in the area. Provides an overview of the current and potential future use of metabolomics in the food industry Chapters focus on key applications and review the analytical methods used and the bioinformatics techniques involved in processing the results Discusses metabolomics in nutrition, human samples for health assessments, and current methods for the analysis of human milk oligosaccharides (HMOs) and their novel applications







The Sugar Beet Crop


Book Description

D.A. Cooke and R.K. Scott Sugar beet is one of just two crops (the other being sugar cane) which constitute the only important sources of sucrose - a product with sweeten ing and preserving properties that make it a major component of, or additive to, a vast range of foods, beverages and pharmaceuticals. Sugar, as sucrose is almost invariably called, has been a valued compo nent of the human diet for thousands of years. For the great majority of that time the only source of pure sucrose was the sugar-cane plant, varieties of which are all species or hybrids within the genus Saccharum. The sugar-cane crop was, and is, restricted to tropical and subtropical regions, and until the eighteenth century the sugar produced from it was available in Europe only to the privileged few. However, the expansion of cane production, particularly in the Caribbean area, in the late seventeenth and the eighteenth centuries, and the new sugar-beet crop in Europe in the nineteenth century, meant that sugar became available to an increasing proportion of the world's population.
