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
This chapter reviews the present status of genetic and genomic resources of Lathyrus and their use in current breeding programmes.
Pigeon pea (Cajanus cajan (L.) Millspaugh) is an important grain legume crop grown in tropical and subtropical regions of the world.
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.
Lentil (Lens culinaris spp. culinaris) has a long history associated with the early civilizations 11,000 BP in southwestern Asia.
Cowpea (Vigna unguiculata), an indigenous legume to sub-Saharan Africa, is mainly grown in the dry savanna areas as an intercrop with millets, sorghum, groundnut and maize.
In India, the National Bureau of Plant Genetic Resources (NBPGR), New Delhi, is a nodal agency for the collection, conservation and documentation of horse gram germplasm; a total of 1627 accessions of horse gram are conserved in its gene ...
These are ideal crops for achieving three simultaneous developmental goals viz. reducing poverty, improving human health and nutrition and enhancing ecosystem resilience.
This book serves as a reference resource to legumes researchers for the use of genome information twoard the improvement of major legume crops.
relatives as sources of new germplasm is well established in breeding programmes for crop improvement on a worldwide ... legume crop species, the wild related species do not form a particularly extensive or accessible genetic resource.
