This book focuses on the previously neglected interface between the conservation of plant genetic resources and their utilization. Only through utilization can the potential value of conserved genetic resources be realized. However, as this book shows, much conserved germplan has to be subjected to long term pre-breeding and genetic enhancement before it can be used in plant breeding programs. The authors explore the rationale and approaches for such pre-breeding efforts as the basis for broadening the genetic bases of crop production. Examples from a range of major food crops are presented and issues are analyzed by leading authorities from around the world.

Grain legumes play significant and diverse role in the farming systems and provide nutrition security to the largely vegetarian and relatively poorer people around the world. These are ideal crops for achieving three simultaneous developmental goals viz. reducing poverty, improving human health and nutrition and enhancing ecosystem resilience. Globally, grain legumes are the second most important crop group next only to cereals but a large proportion of area of it is under rainfed-low input systems as compared to cereals contributing to lower yields. The other important factor responsible for reduced yield in grain legumes is the narrow genetic base of the present day pulse varieties. In order to break the yield barriers of these cultivars, new sources of genes/ alleles need to be identified and suitably incorporated into the adapted background. The information on various aspects of grain legume improvement although has been considerable in the recent past, these information are highly scattered and not available at one place. The present book consists of comprehensive and latest crop-wise information on important grain legumes of the world including their distribution, gene pool, systematics, status of genetic and genomic resources, production constraints, traits of importance, crop improvement methodologies - both conventional as well as contemporary and future strategies to be adopted for comprehensive grain legume improvement in various agro-ecological target areas of the globe. The chapters have been contributed by eminent crop experts from across the world engaged in research in their respective crops for the past several years thus providing a rare insight into the crop specific constraints and prospects drawing from their rich overall experience. The book therefore will be a useful source of information to the grain legume researchers, students, policy planners and developmental experts alike.

This book offers comprehensive coverage of important grain cereals including their origin and distribution, crop gene pool, level of diversity, production constraints, traits of importance for genetic base widening, crop improvement methodologies, genome mapping, genomics for breeding, and future strategies. The chapters, contributed by eminent crop researchers from around the world, provide rare insights into the crop-specific constraints and prospects drawing from their substantial experience. As such, the book offers an essential source of information for grain cereals scientists, teachers, students, policy planners and developmental experts alike. Grain cereals, which comprise rice, wheat, maize, barley, oats, sorghum and millets, are members of the grass family. These crops are vital to human nutrition, thanks to their roles as staple food crops in different parts of the globe. Some of them are rich sources of carbohydrates, which provide energy, while others are important sources of minerals, vitamins and proteins, in addition to their medicinal properties. In most cereals, the existing variability among elite germplasm has been exploited to attain a desirable level of productivity. However, to make further breakthroughs in enhancing yield and improving stability in future crop cultivars, new sources of genes/alleles need to be identified in wild/weedy species and incorporated into the cultivated varieties. Though there have been many publications on various aspects of grain cereal improvement in the recent past, to date this essential information has remained scattered among different periodicals.

Plant breeding is the art and science of changing the genetics of plants for the benefit of humankind. A major goal of plant breeders is to select genotypes with stable and high performing phenotypes across environments. However, a selected genotype often performs differently across environments. This book presents a comprehensive review of various stability analysis methods and their application in plant breeding for selection of stable and high performing genotypes. Additionally, efficient methods to produce doubled haploid plants and to provide embryogenic suitable haploid cells systems are needed for future genetic manipulations and breeding in bread and durum wheat. This book describes a new stress in durum wheat, for its effectiveness to induce embryogenesis and regeneration plants. Along with its implications for plant selection, the methods used for dose-response variation are also explored, as well as the relationship between genetic variation and changes in dose-response behaviour. Other chapters in this book discuss the breeding strategy of self-incompatibility, an evolutionary force to preserve genetic variability in plants, the pros and cons of marker-assisted selection (MAS) breeding along with its future prospects, and the use of Joint Regression Analysis (JRA) in the management of plant breeding programs.
