This book is the first comprehensive compilation of deliberations on whole genome sequencing of the diploid and tetraploid alfalfa genomes including sequence assembly, gene annotation, and comparative genomics with the model legume genome, functional genomics, and genomics of important agronomic characters. Other chapters describe the genetic diversity and germplasm collections of alfalfa, as well as development of genetic markers and genome-wide association and genomic selection for economical important traits, genome editing, genomics, and breeding targets to address current and future needs. Altogether, the book contains about 300 pages over 16 chapters authored by globally reputed experts on the relevant field in this crop. This book is useful to the students, teachers, and scientists in the academia and relevant private companies interested in genetics, breeding, pathology, physiology, molecular genetics and breeding, biotechnology, and structural and functional genomics. The work is also useful to seed and forage industries.

Grassland covers 26% of the world’s total land area. It produces feed for livestock; maintains soil fertility; protects and conserves soil and water resources; creates a habitat for wildlife; provides recreational space for sport and leisure and contributes to the general landscape. This book provides an up-to-date account of progress and potential in the genetic improvement of grassland to meet all needs. It encompasses work on a wide range of temperate and tropical grassland species (including grasses, clovers and other forage legumes) and will interest all those concerned with grassland use in livestock-based agriculture, recreation, environmental protection, bio-industry etc. Specifically, it demonstrates how recent advances in molecular techniques are being used to develop breeding objectives and strategies with key-note papers on: Objectives and benefits of molecular breeding, Linkage/physical mapping and map-based cloning, QTL analysis and trait dissection, Genomics, model species, gene discovery and functional analysis, Use of molecular markers and bioinformatics for breeding, Molecular genetics and breeding of endosymbiont and grass/legume associations, Transgenics, Genetic diversity, breeding systems and resources Future directions for research and breeding. State-of-the-art molecular techniques and resources are described that encompass a unique range of expertise in genetic mapping, trait dissection, comparative genomics, bioinformatics, gene discovery and risk assessment. Examples of work in progress or recently completed are provided from across the world. The book has broad educational value and will interest plant geneticists and breeders as well as grassland users and policy makers.

Global demand for food is rising as a result of increases in the global population as well as dietary changes. Furthermore, climate change exerts additional pressure on the food supply, adversely affecting sustainable food production. Increased temperatures and drought stresses coupled with the migration of pests limit crop yields and affect their nutritional quality. Many staple crops are unable to adapt to these changing climatic conditions. To achieve the Sustainable Development Goals of the United Nation to end hunger and promote good health and well-being, concerted efforts need to be made to enhance food production while mitigating the effects of climate change through the promotion of climate-smart agricultural practices and the utilization of neglected and underutilized crop species. These species can be highly nutritious and well-adapted to different agroecologies and climatic conditions, meaning that they offer the possibility of improving food and nutritional security.
