Legume crops provide an excellent source of high quality plant protein and have a key role in arable crop rotations reducing the need for fertilizer application and acting as break-crops. However, these crops are affected by a number of foliar and root diseases, being ascochyta blights the most important group of diseases worldwide. Ascochyta blights are incited by different pathogens in the various legumes. A number of control strategies have been developed including resistance breeding, cultural practices and chemical control. However, only marginal successes have been achieved in most instances, most control methods being uneconomical, hard to achieve or resulting in incomplete protection. This eBook covers recent advances in co-operative research on these diseases, from agronomy to breeding, covering traditional and modern genomic methodologies.

The edited book covers all major and minor diseases in grain legumes (chickpea, pigeon pea, lentil, mung bean, common bean, groundnut, and soybean) and forages legumes (including Medicago, rice bean, and faba bean) and their control measures by using various breeding approaches. Grain legumes are versatile nutritionally rich crops, and are one of the important components of global food security. However, grain legumes are severely challenged by various major and emerging minor diseases causing serious limitations in grain yield and production. Thus, to minimize the negative impact of the growing yield loss caused by these diseases, several approaches have been developed and embraced. This book covers all the latest development in genetics, breeding, genomics, and molecular biology tools for combating various major and minor emerging diseases in all the grain legumes from expert authors. Chapters in this title contain all the relevant illustrations and statistical data detailing the present scenario and identifying the gap for meeting the future demand for sustaining global protein security by developing disease-resistant cultivars. This book is of interest to graduate and postgraduate students, researchers, and policymakers to understand the impacts of various diseases on yield loss in legume crops.

This book is devoted to grain legumes and include eight chapters devoted to the breeding of specific grain legume crops and five general chapters dealing with important topics which are common to most of the species in focus. Soybean is not included in the book as it is commonly considered an oil crop more than a grain legume and is included in the Oil Crops Volume of the Handbook of Plant Breeding.Legume species belong to the Fabaceae family and are characterized by their fruit, usually called pod. Several species of this family were domesticated by humans, such as soybean, common bean, faba bean, pea, chickpea, lentil, peanut, or cowpea. Some of these species are of great relevance as human and animal food. Food legumes are consumed either by their immature pod or their dry seeds, which have a high protein content. Globally, grain legumes are the most relevant source of plant protein, especially in many countries of Africa and Latin America, but there are some constraints in their production, such as a poor adaptation, pest and diseases and unstable yield. Current research trends in Legumes are focused on new methodologies involving genetic and omic studies, as well as new approaches to the genetic improvement of these species, including the relationships with their symbiotic rhizobia.

The protein molecule is the basic building block of every living entity. Its deficiency leads to restricted growth and development of individuals. Globally, such malnutrition is on the rise due to various reasons such as rapid population growth, stagnation of productivity, and ever-rising costs. Millions of people, especially in developing and under-developed countries, suffer from protein malnutrition and the only possible solution is to encourage farmers to grow high-protein food legume crops in their fields for domestic consumption. This, however, could be possible if farmers are provided with new cultivars with high yield, and resistance to major insects, diseases, and key abiotic stresses. The major food legume crops are chickpea, cowpea, common bean, groundnut, lentil, pigeonpea, and soybean. Predominantly, the legume crops are grown under a subsistence level and, therefore, in comparison to cereals and horticultural crops their productivity is low and highly variable. The crop breeders around the globe are engaged in breeding suitable cultivars for harsh and changing environments but success has been limited and not up to needs. With the recent development of new technologies in plant sciences, efforts are being made to help under-privileged farmers through breeding new cultivars which will produce more protein per unit of land area. In this book, the contributors analyze the constraints, review new technologies, and propose a future course of crop breeding programs in seven cold and warm season legume crops.

Faba bean was first domesticated in the Near East about 10,000 BC. It is now grown worldwide on 2.56 million ha with a yield of 4.56 million tons. The traditional landraces are affected by the different biotic and abiotic stresses. Replacement of these low-yielding landraces by improved cultivars has resulted in a yield increase of 15.4kg/ha/year over the last 40 years. A reduction of the planted area from 7.5 million ha in 1961 to 2.56 million ha in 2010 and cultivation of improved cultivars are the major causes of genetic erosion. Gene banks around the world conserved more than 36,000 accessions. Diversity studies showed limited variation among currently grown cultivars, but high variation among different botanical groups has been recorded. The International Center for Agricultural Research in the Dry Areas has undertaken desirable selection and breeding efforts to identify different sources of resistance and to develop improved varieties in collaboration with national agricultural research systems. A molecular approach was used in advanced research institutes to tag major genes/quantitative trait loci with molecular markers. However, more efforts are needed to saturate the genetic maps to facilitate marker-assisted breeding.

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.

Grain legumes, including common-bean, chickpea, pigeonpea, pea, cowpea, lentil and others, form important constituents of global diets, both vegetarian and non-vegetarian. Despite this significant role, global production has increased only marginally in the past 50 years. The slow production growth, along with a rising human population and improved buying capacity has substantially reduced the per capita availability of food legumes. Changes in environmental climate have also had significant impact on production, creating a need to identify stable donors among genetic resources for environmentally robust genes and designing crops resilient to climate change. Genetic and Genomic Resources of Grain Legume Improvement is the first book to bring together the latest resources in plant genetics and genomics to facilitate the identification of specific germplasm, trait mapping and allele mining to more effectively develop biotic and abiotic-stress-resistant grains. This book will be an invaluable resource for researchers, crop biologists and students working with crop development. Explores origin, distribution and diversity of grain legumes Presents information on germplasm collection, evaluation and maintenance Offers insight into pre-breeding/germplasm enhancement efforts Integrates genomic and genetic resources in crop improvement Internationally contributed work
