Book Description
Seed quality is crucial for a satisfactory crop establishment. It is also an important part of the process of breeding for sustainable farming systems, where varieties often grow under more difficult conditions than in conventional farming systems. Previous research suggests that corn genotypes and the environment where seeds are produced have an effect on seed quality. The objective of this study was to determine seed quality differences between organic and conventional farming systems. Twenty high protein breeding genotypes derived from exotic by adapted crosses were planted during two growing seasons in conventional and organic nurseries near Ames, Iowa, to produce seeds for laboratory tests. The laboratory tests to assess germination and vigor included: standard germination, saturated cold test, accelerated aging and soak test. Complementary tests such as fast green and electrical conductivity were performed to assess mechanical damage and membrane integrity of seeds, respectively. Protein and oil compositions also were analyzed by NIR. The standard germination and saturated cold test indicated that genotype and environment where seeds were produced affected seed quality. The germination and saturated cold test percentages of seeds produced in the organic farming system were lower than for seeds produced in the conventional system. The interactions between location and genotype was non significant in 2003 and 2004. These results indicate that selection of high seed quality genotypes for the organic system can be accomplished in the conventional system. Genotype also influences the protein and oil content of the seed. Protein was unaffected by the production environment, but oil content depended on environment. The oil content of seeds produced in the organic system was significantly higher than in the conventional system. This is important when selecting high protein lines in a conventional system as protein content will remain high when lines are grown in the organic farming system.

Book Description
Corn: Chemistry and Technology, Third Edition, provides a broad perspective on corn from expert agronomists, food scientists and geneticists. This encyclopedic storehouse of comprehensive information on all aspects of the world’s largest crop (in metric tons) includes extensive coverage of recent development in genetic modification for the generation of new hybrids and genotypes. New chapters highlight the importance of corn as a raw material for the production of fuel bioethanol and the emerging topic of phytochemicals or nutraceutical compounds associated to different types of corns and their effect on human health, especially in the prevention of chronic diseases and cancer. Written by international experts on corn, and edited by a highly respected academics, this new edition will remain the industry standard on the topic. Presents new chapters that deal with specialty corns, the production of first generation bioethanol, and the important relationship of corn phytochemicals or nutraceuticals with human health Provides contributions from a new editor and a number of new contributors who bring a fresh take on this highly successful volume Includes vastly increased content relating to recent developments in genetic modification for the generation of new hybrids and genotypes Contains encyclopedic coverage of grain chemistry and nutritional quality of this extensively farmed product Covers the production and handling of corn, with both food and non-food applications

Book Description
Plants have been successfully selectively bred for thousands of years, culminating in incredible yields, quality, resistance and so on that we see in our modern day crops and ornamental plants. In recent years the techniques used have been rapidly advanced and refined to include molecular, cell and genetic techniques. An Introduction to Plant Breeding provides comprehensive coverage of the whole area of plant breeding. Covering modes of reproduction in plants, breeding objectives and schemes, genetics, predictions, selection, alternative techniques and practical considerations. Each chapter is carefully laid out in a student friendly way and includes questions for the reader. The book is essential reading for all those studying, teaching and researching plant breeding.

Book Description
Nitrogen fixation by leguminous plants is especially important when farmers are trying to minimise fertilizer use for cost or environmental reasons. This second edition of the highly successful book, first published in 1991, contains thoroughly updated and revised material on the theory and practice of nitrogen fixation in tropical cropping systems.
