​The study of origin and domestication of legumes described in this book emerged when it became apparent that while this kind of information is adequate for cereals, the pulses lagged behind. At the end of the 1960s the senior author initiated a study on the chickpea's wild relatives followed by similar attempts for broad bean, fenugreek, common vetch, bitter vetch, and lentil. The junior author joined the project in the late 1980s with a study of the genetics of interspecific hybrid embryo abortion in lentil and later has extensively investigated chickpea domestication and wild peas. While this book mainly describes our research findings, pertinent results obtained by others are also discussed and evaluated. Studying the wild relatives of legumes included evaluation of their taxonomic status, their morphological variation, ecological requirements, exploration of their distribution, and seed collection in their natural habitats. Seeds were examined for their protein profile as preliminary hints of their affinity to the cultigens and plants grown from these seeds were used for establishing their karyotype, producing intra- and interspecific hybrids and analyses of their chromosome pairing at meiosis and fertility. The aim of these investigations was the identification of the potential wild gene pool of the domesticated forms. Assessment of genetic variation among accessions, particularly in the genus Lens, was made by isozymes and chloroplast DNA studies. The main findings include the discovery of the chickpea wild progenitor; studies of lentil in three crossability groups; wild peas proceeded in two lines of study; faba bean and fenugreek and their wild progenitors have not yet been identified; common vetch and its related form were treated here as an aggregate (A. sativa); we found gene flow between members of different karyotypes is possible; bitter vetch and its relation to the domesticated form were established by breeding experiments.
Grain legume crops are an important component of global food and nutritional security and help in maintaining agro-ecological systems. They fix atmospheric nitrogen via the root-inhabiting rhizobacteria, thereby minimising the harmful effects caused by the excessive application of synthetic nitrogenous fertilizers in the soil environment. There has been less focus on legume crop wild relatives for harnessing their potential traits and novel gene(s) to incorporate them into the cultivated legumes for developing climate-resilient grain legumes. In this edited book, we will highlight the importance of various potential traits of crop wild relatives, which are yet to be properly harnessed for designing future climate-resilient grain legumes. We also update how advances in molecular genetics and genomics have enabled the underpinning of several candidate genes/genomic regions in various crop wild relatives harbouring adaptive traits that confer climate resilience in grain legumes. Readers will benefit from new information on various crop wild relatives in grain legumes and how these wild relatives could be explored for novel climate resilience genes for developing future climate-resilient legume crops. They will gain an understanding of how genomic advances (genome sequence, pan genomes) have uncovered the novel genomic regions attributed to climate resilience in various grain legumes. Finally, the critical role of these wild relatives in maintaining the lost gene(s) due to the domestication process will be discussed. Comprehensive information on conventional breeding, advanced breeding, and recent advances in genomics covering all the major crop wild relatives of legumes is not available in a single book. Thus, this book will provide readers with the latest updates on various information covering all aspects of wild species of legumes.
Lexicon of Pulse Crops integrates botanical and linguistic data to analyze and interpret the grain legume significance from the earliest archaeological and written records until the present day. Aimed at both agronomic and linguistic research communities, this book presents a database containing 9,500 common names in more than 900 languages and dialects of all ethnolinguistic families, denoting more than 1,100 botanical taxa of 14 selected pulse crop genera and species. The book begins with overviews of the world’s economically most important grain legume crops and their uncultivated relatives, as well as the world’s language families with their inner structure, including both extinct and living members. The main section of the text presents 14 specialized book chapters covering Arachis, Cajanus, Cicer, Ervum, Faba, Glycine, Lablab, Lathyrus, Lens, Lupinus, Phaseolus, Pisum, Vicia, and Vigna. They provide the reader with extensive lists of the botanically accepted species and subtaxa and surveys lexicological abundance in all world’s ethnolinguistic families, comprising extinct and living as well as natural and constructed languages, while the vernacular names for the most significant taxa are presented in comprehensive tables. Each of these chapters also presents the existing etymologies and novel approaches to deciphering the origins of common names, accompanied by one original color plate depicting possible root evolutions in the form of corresponding pulse crop plants.
Plant improvement has shifted its focus from yield, quality and disease resistance to factors that will enhance commercial export, such as early maturity, shelf life and better processing quality. Conventional plant breeding methods aiming at the improvement of a self-pollinating crop, such as wheat, usually take 10-12 years to develop and release of the new variety. During the past 10 years, significant advances have been made and accelerated methods have been developed for precision breeding and early release of crop varieties. This work summarizes concepts dealing with germplasm enhancement and development of improved varieties based on innovative methodologies that include doubled haploidy, marker assisted selection, marker assisted background selection, genetic mapping, genomic selection, high-throughput genotyping, high-throughput phenotyping, mutation breeding, reverse breeding, transgenic breeding, shuttle breeding, speed breeding, low cost high-throughput field phenotyping, etc. It is an important reference with special focus on accelerated development of improved crop varieties.
Biotic stresses cause yield loss of 31-42% in crops in addition to 6-20% during post-harvest stage. Understanding interaction of crop plants to the biotic stresses caused by insects, bacteria, fungi, viruses, and oomycetes, etc. is important to develop resistant crop varieties. Knowledge on the advanced genetic and genomic crop improvement strategies including molecular breeding, transgenics, genomic-assisted breeding and the recently emerging genome editing for developing resistant varieties in pulse crops is imperative for addressing FPNEE (food, health, nutrition. energy and environment) security. Whole genome sequencing of these crops followed by genotyping-by-sequencing have facilitated precise information about the genes conferring resistance useful for gene discovery, allele mining and shuttle breeding which in turn opened up the scope for 'designing' crop genomes with resistance to biotic stresses. The nine chapters each dedicated to a pulse crop in this volume elucidate on different types of biotic stress agents and their effects on and interaction with the crop plants; enumerate on the available genetic diversity with regard to biotic stress resistance among available cultivars; illuminate on the potential gene pools for utilization in interspecific gene transfer; present brief on the classical genetics of stress resistance and traditional breeding for transferring them to their cultivated counterparts; depict the success stories of genetic engineering for developing biotic stress resistant varieties; discuss on molecular mapping of genes and QTLs underlying biotic stress resistance and their marker-assisted introgression into elite varieties; enunciate on different emerging genomics-aided techniques including genomic selection, allele mining, gene discovery and gene pyramiding for developing resistant crop varieties with higher quantity and quality of yields; and also elaborate some case studies on genome editing focusing on specific genes for generating disease and insect resistant crops.

Clothing was crucial in human evolution, and having to cope with climate change was as true in prehistory as it is today. In Climate, Clothing, and Agriculture in Prehistory, Ian Gilligan offers the first complete account of the development of clothing as a response to cold exposure during the ice ages. He explores how and when clothes were invented, noting that the thermal motive alone is tenable in view of the naked condition of humans. His account shows that there is considerably more archaeological evidence for palaeolithic clothes than is generally appreciated. Moreover, Gilligan posits, clothing played a leading role in major technological innovations. He demonstrates that fibre production and the advent of woven fabrics, developed in response to global warming, were pivotal to the origins of agriculture. Drawing together evidence from many disciplines, Climate Clothing, and Agriculture in Prehistory is written in a clear and engaging style, and is illustrated with nearly 100 images.
