Pigeonpea (Cajanus cajan) is a crop of small land holding farmers in arid and semi-arid regions of the world. It has a number of usages starting from protein rich food to vegetarian families; fuel wood; nitrogen supplier to soil; recycling minerals in soil to animal feed etc. Pigeonpea has been considered to be originated and domesticated in central India from where it travelled to different parts of the world such as Africa and Latin America. In ongoing scenario of climate change, biotic and especially abiotic stresses will make the conditions more challenging for entire agriculture. This volume focusing on the pigeonpea genome will collate the information on the genome sequencing and its utilization in genomics activities, with a focus on the current findings, advanced tools and strategies deployed in pigeonpea genome sequencing and analysis, and how this information is leading to direct outcomes for plant breeders and subsequently to farmers.

Oilseeds and legumes provide a significant proportion of the protein and energy requirements of the world population. This important new book provides comprehensive details of the main oil seed and legume crops focusing particularly on the nutritional aspects of these crops which are, or have the potential to be, more widely exploited in developing countries where are or have the potential to be, more widely exploited in developing countries where protein and energy malnutrition continue to escalate. The predicted rapid rise of populations in many world regions which are increasingly vulnerable to food shortages means that a full knowledge of the nutritional significance of available crops is vital in helping to prevent potential calamities. Food and Feed from Legumes and Oil Seeds has been written by a team of international contributors, each with direct experience of these important crops and their nutritional merits, and the editors are both international experts in the crops covered. This book will become of great value to nutritionists, food and feed scientists and technologists, agricultural scientists and all those involved with overseas developments and food aid organizations.

An account of the evolution and principles involved in breeding crops grown in the tropics. This book developed from a symposium held in New Delhi in 1970 at the Indian Agricultural Research Institute. It begins with a consideration of the history of agriculture. Recent techniques make is possible to set crop plant evolution against the time scale of agricultural development, enabling the rate of evolution to be determined with some precision. Throughout the account the studies stress the range of material and changes and improvements in crops, with special reference to their importance not only in the tropics, but also to world agriculture. This book brings to the notice of geneticists and breeders in western countries the work undertaken in India in elucidating the evolution and recent improvement of crop plants of world wide importance. It is also an authoritative account for students of plant breeding in the tropics taking courses in universities, in institutes and colleges of agriculture who need to have within the covers of one book a comprehensive, yet concise text that clearly sets out the principles involved in the breeding of crops grown in the tropics.

Chickpea is an important protein-rich crop with considerable diversity present among 44 annual Cicer species. A large collection of chickpea germplasm including wild Cicer species has been conserved in different gene banks globally. However, the effective and efficient utilization of these resources is required to develop new cultivars with a broad genetic base. Using core and mini-core collections, chickpea researchers have identified diverse germplasm possessing various beneficial traits that are now being used in chickpea breeding. Further, for chickpea improvement, the genus Cicer harbours alleles/genes for tolerance/resistance to various abiotic and biotic stresses as well as for agronomic and nutrition-related traits. Recent advances in plant biotechnology have resulted in developing large number of markers specific to chickpea in addition to technological breakthrough in developing high-throughput genotyping platforms for unlocking the genetic potential available in germplasm collections.

" . . . . . . Nature has something more in view than that its own proper males should fecundate each blossom. " Andrew Knight Philosophical Transactions, 1799 Sterility implicating the male sex solely presents a paradoxical situation in which universality and uniqueness are harmoniously blended. It maintains a built-in outbreeding system but is not an isolating mechanism, as male steriles, the "self-emasculated" plants, outcross with their male fertile sibs normally. Both genes (nuclear and cytoplasmic) and environment, individually as well as conjointly, induce male sterility, the former being genetic and the latter nongenetic. Genetic male sterility is controlled either exclusively by nuclear genes (ms) or by the complementary action of nuclear (lr) and cytoplasmic (c) genes. The former is termed genic and the latter gene-cytoplasmic male sterility. Whereas genic male sterility exhibits Mendelian inheritance, gene-cytoplasmic male sterility is non-Mendelian, with specific transmissibility of the maternal cytoplasm type. Genetic male sterility is documented in 617 species and species crosses com prising 320 species, 162 genera and 43 families. Of these, genic male sterility occurs in 216 species and 17 species crosses and gene-cytoplasmic male sterility in 16 species and 271 species crosses. The Predominance of species exhibiting genic male sterility and of species crosses exhibiting gene-cytoplasmic male sterility is due to the fact that for the male sterility expression in the former, mutation of nuclear genes is required, but in the latter, mutations of both nuclear and cytoplasmic genes are necessary.

The improvement of crop species has long been a goal since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and legumes are expected to lead as the most important crops in the world. Due to environmental fluctuations legumes are often exposed to different environmental stresses, leading to decreased yield and problems with growth and development of the legumes. The present work will cover the physiobiochemical, molecular and omic approaches and responses of legumes towards environmental stress. Contributors will be active researchers and practitioners from international institutions and organisations. The book will be a valuable and much-needed resource for plant scientists, breeders and agricultural researchers worldwide.

India, a country with high concentrations of poor and malnourished people, long promoted a cereal-centric diet composed of subsidized staple commodities such as rice and wheat to feed its population of more than a billion. Today, however, dietary patterns are changing. Policy makers, researchers, and health activists are looking for ways to fight hunger and malnutrition in the country. As they shift their focus from calorie intake to nutrition, neglected foods such as pulses (the dried, edible seeds of legumes) are gaining attention. Pulses for Nutrition in India: Changing Patterns from Farm to Fork explores the numerous benefits of a diet that incorporates pulses. Pulses, including pigeonpeas, lentils, and chickpeas, are less expensive than meat and are excellent sources of protein. In India, people consume pulses and other legumes for protein intake. Pulses also benefit the ecosystem. Among protein-rich foods, pulses have the lowest carbon and water footprints. Pulses also improve soil health by naturally balancing atmospheric nitrogen in the soil; thus, growing pulses reduces the need for nitrogenous fertilizer. Pulses for Nutrition in India: Changing Patterns from Farm to Fork looks at the country’s pulses sector in light of agricultural systems, climate change, irrigation design, and how policies (including the Green Revolution) have evolved over time. To understand how pulses can help fulfill the objectives of India’s food policies, experts explore the role that pulse production plays in global trade; the changing demand for pulses in India since the 1960s; the possibility of improving pulse yields with better technology to compete with cereals; and the long-term health benefits of greater reliance on pulses. The analyses in Pulses for Nutrition in India: Changing Patterns from Farm to Fork contribute to the emerging literature on pulses and will aid policy makers in finding ways to feed and nourish a growing population.

Grain legumes, together with quinoa and amaranth (pseudocereals) and other crops are attractive candidates to satisfy the growing demand for plant protein production worldwide for food and feed. Despite their high value, many protein crops have not been adequately assessed and numerous species are underutilized. Special attention has to be paid to genetic diversity and landraces, and to the key limiting factors affecting yield, including water deficiency and other abiotic and biotic stresses, in order to obtain stable, reliable and sustainable crop production through the introduction and local adaptation of genetically improved varieties. Legumes, the main protein crops worldwide, contribute to the sustainable improvement of the environment due to their ability to fix nitrogen and their beneficial effects on the soil. They play a key role in the crop diversification and sustainable intensification of agriculture, particularly in light of new and urgent challenges, such as climate change and food security. In addition, the role of legumes in nutrition has been recognized as a relevant source of plant protein, together with other benefits for health. Chapters dealing with common bean, lupine, soybean, lentil, cowpea and Medicago are included in this book. Most contributions deal with legumes, but the significant number of papers on different aspects of quinoa gives an idea of the increasing importance of this protein crop. Pseudocereals, such as quinoa and amaranth, are good sources of proteins. Quinoa and amaranth seeds contain lysine, an essential amino acid that is limited in other grains. Nutritional evaluations of quinoa indicate that it constitutes a source of complete protein with a good balance among all of the amino acids needed for human diet, and also important minerals, vitamins, high quality oils and flavonoids. Other protein crops also included in this book are hemp, cotton and cereals (maize, wheat and rice). Although cereals protein content is not high, their seeds are largely used for human consumption. In this book are included articles dealing with all different aspects of protein crops, including nutritional value, breeding, genetic diversity, biotic and abiotic stress, cropping systems or omics, which may be considered crucial to help provide the plant proteins of the future. Overall, the participation of 169 authors in 29 chapters in this book indicates an active scientific community in the field, which appears to be an encouraging reflect of the global awareness of the need for sustainability and the promising future of proteins crops as a source of food and feed.
