Cash crops are grown and sold for monetary gain and not necessarily for sustenance. They include coffee, tea, coconut, cotton, jute, groundnut, castor, linseed, cocoa, rubber, cassava, soybean, sweet potato, potato, wheat, corn and teff. While some of these crops have been improved for realizing yield potential, breeding of many of them is still in infancy. Crops that underwent rigorous breeding have eventually lost much of the diversity due to extensive cultivation with a few improved varieties and the diversity in less bred species is to be conserved. Over the past years, scholars and policy makers have become increasingly aware of the short and long-run impact of climatic factors on economic, food security, social and political outcomes . Genetic diversity, natural and induced, is much needed for the future generations to sustain food production with more climate resilient crops. In contrast, crop uniformity produced across the farm fields in the form ofimproved varieties is genetically vulnerable to biotic and abiotic stresses. Thus, it is essential and challenging to address the issue of compromising between maximizing crop yield under a given set of conditions and minimizing the risk of crop failure when conditions change. Cash crops are grown in an array of climatic conditions. Many of the world¿s poor still live in rural areas. Many are subsistence farmers, operating very small farms using very little agricultural inputs for achieving marketable outputs. Conserving the diversity of these crops and addressing all issues of crop culture through modern tools of biotechnology and genomics is a real challenge. We believe the focus of this book is to fill an unmet need of this and other grower communities by providing the necessary knowledge, albeit indirectly via the academics, to manage the risks of cash crops breeding through managing genetic diversity.

This book highlights the recent progress on the applications of mutation breeding technology in crop plants. Plant breeders and agriculturists are faced with the new challenges of climate change, human population growth, and dwindling arable land and water resources which threaten to sustain food production worldwide. Genetic variation is the basis which plant breeders require to produce new and improved cultivars. The understanding of mutation induction and exploring its applications has paved the way for enhancing genetic variability for various plant and agronomic characters, and led to advances in gene discovery for various traits. Induced mutagenesis has played a significant role in crop improvement and currently, the technology has resulted in the development and release of more than 3600 mutant varieties in most of the crop plants with great economic impact. The field of ¿mutation breeding¿ has come long way to become an important approach for crop improvement. This book covers various methodologies of mutation induction, screening of mutants, genome editing and genomics advances and mutant gene discovery. The book further discusses success stories in different countries and applications of mutation breeding in food crops, horticultural plants and plantation crops.This informative book is very useful to plant breeders, students and researchers in the field of agriculture, plant sciences, food science and genetics.

This book is the first comprehensive assemblage of contemporary knowledge relevant to genomics and other omics in date palm. Volume 2 consists of 11 chapters. Part I, Nutritional and Pharmaceuticals Properties, covers the utilization of date palm as an ingredient of various food products, a source of bioactive compounds and the production of nanomaterials. Part II, Omics Technologies, addresses omics resources, proteomics and metabolomics. Part III, Molecular Breeding and Genome Modification, focuses on genetic improvement technologies based on mutagenesis, quantitative traits loci and genome editing. Part IV, Genomics of Abiotic and Biotic Stress, covers metagenomics of beneficial microbes to enhance tolerance to abiotic stress and the various genomics advances as they apply to insect control. This volume represents the efforts of 34 international scientists from 12 countries and contains 65 figures and 19 tables to illustrate presented concepts. Volume 1 is published under the title: Phylogeny, Biodiversity and Mapping.

Today, in a world with abundant food, more than 700 million people are chro- cally undernourished. Over the next 20 years, the world's population will probably double. The global food supply would need to double or to triple for the larger population to be fed adequately. Agriculture is closely linked to environmental quality in a variety of ways, and the challenge of our generation is how to feed a growing planet while maintaining the integrity of our ecological life-support system. The responsibility of governments for ensuring food security will grow proportionately with the growth of populations, and governments bear a special responsibility for promoting agricultural inputs. Agriculture in the 21st century, will certainly focus increasingly on adapting modern technologies to local farming systems, needs and environments. Worldwide climatic changes have been raising concerns about potential changes to crop yields and production systems. Such concerns include the ability to acc- modate these uncertain effects in order to ensure an adequate food supply for an increasing population. What can be done concretely to use agriculture to address some of the fundamental issues of today's world? We must recognize that agric- ture is part of the solution and not just a problem. Agricultural development is a key to social stability and equity in many parts of the world. It can help to al- viate the subtle and unspoken fears of modernization and the space of change if innovation is handled transparently.
