Crop growth and productivity is limited by a large number of adverse conditions of ambient environment and soil composition. Among these, drought and soil salinity are most prevalent stresses. In view of shrinking land resources and continuing pressures of growing population in most developing countries, it has become imperative that crop yields are not allowed to suffer on any type of cultivable land. Breeding crop varieties resistant to drought and salinity stress, therefore, assumes great importance. Major limitations to exploiting genetic resistance have been the lack of (i) definition of the level of stress that is relevant to crop productivity, (ii) screening procedures that can be reliably employed for identifying genotypes possessing attributes governing stability of performance under stress conditions, and (iii) Understanding of the processes that have direct as well as indirect relevance to conferment of resistance. This book presents the much-needed information on drought and salinity stress under one cover. s have been contributed by a leading authority and practitioner of his own field of specialization. The book will be an indispensable source of information for students and researchers interested in the subject of drought and salinity stresses and breeding approaches for achieving resistance to these stresses.

Salinity tolerance in plants is a complex problem encompassing numerous morphological, physiological and biochemical processes and adaptations at the cellular, sub-cellular and whole plant levels. The book comprising eleven chapters deals with diverse aspects of salt tolerance including plant response to salinity and sodicity, crop tolerance at different growth stages and criteria for evaluating the same. The mechanism of salt injury viz. osmotic, ionic and nutrient imbalance has been dealt with, adopting an integrated appraoch. Likewise, the recent information on photosynthesis, respiration, carbohydrate, nitrogen and protein metabolism, enzyme dynamics and plant hormones, as well as nodulation and symbiotic nitrogen fixation in legumes has been elaborated comprehensively. Special attention has been given to the interaction between essential nutrients and salinity as it is vital for alleviation of adverse effects of salt stress. The synthesis of knowledge on different mechanisms of salt resistance, including osmoregulation with organic and inorganic solutes has also been presented. Various methods of introducing salt tolerance in plants such as breeding, genetic variations, physiological approaches, tissue culture, somaclonal variation, somatic hybridation and recombinat DNA technology have been discussed. The nature and properties of salt affected soils and groundwaters and principles for amelioration and management of these critical problems have been included in this book. Furthermore, Afforestation and Agroforestry techniques for salt affected soils with emphasis on salt tolerant tree species and suitable tree crop combinations also find their much needed due space in the present book.

During the past 15 years, cellular and molecular approaches have emerged as valuable adjuncts to supplement and complement conventional breeding methods for a wide variety of crop plants. Biotechnology increasingly plays a role in the creation, conservation, characterization and utilization of genetic variability for germplasm enhancement. For instance, anther/microspore culture, somaclonal variation, embryo culture and somatic hybridization are being exploited for obtaining incremental improvement in the existing cultivars. In addition, genes that confer insect- and disease-resistance, abiotic stress tolerance, herbicide tolerance and quality traits have been isolated and re-introduced into otherwise sensitive or susceptible species by a variety of transgenic techniques. Together these transformative methodologies grant access to a greater repertoire of genetic diversity as the gene(s) may come from viruses, bacteria, fungi, insects, animals, human beings, unrelated plants or even be artificially derived. Remarkable achievements have been made in the production, characterization, field evaluation and commercialization of transgenic crop varieties worldwide. Likewise, significant advances have been made towards increasing crop yields, improving nutritional quality, enabling crops to be raised under adverse conditions and developing resistance to pests and diseases for sustaining global food and nutritional security. The overarching purpose of this 3-volume work is to summarize the history of crop improvement from a technological perspective but to do so with a forward outlook on further advancement and adaptability to a changing world. Our carefully chosen “case studies of important plant crops” intend to serve a diverse spectrum of audience looking for the right tools to tackle complicated local and global issues.

Abiotic stresses have become an integral part of crop production. One or other persist either in soil, water or in atmosphere. The information in the areas of injury and tolerant mechanisms, variability for tolerance, breeding and biotechnology for improvement of crop plants against abiotic stresses are lying unorganized in different articles of journals and edited books. This information is presented in this book in organized way with up-to-date citations, which will provide comprehensive literatures of recent advances. More emphasis has been given to elaborate the injury and tolerance mechanisms, and development of improved genotypes against stress environments. This book also deals with the plants' symptoms of particular abiotic stress, reclamation of soil and crop/cropping pattern to over come the effect of adverse condition(s). Each has been laid out with systematic approaches to develop abiotic stress tolerant genotypes using biotechnological tools. Use of molecular markers in stress tolerance and development of transgenic also have been detailed. Air pollution and climate change are the hot topic of the days. Thus, the effect of air pollution and climate change on crop plants have been detailed in the final three s of this book. Under abiotic stress, plant produces a large quantity of free radicals (oxidants), which have been elaborated in a separate 'Oxidative Stress'. This book has been divided into seven major parts- physical stress (salt), water stresses (drought and waterlogging), temperature stresses (heat and cold), metal toxicities (aluminium, iron, cadmium, lead, nickel, chromium, copper, zinc etc) and non-metal toxicities (boron and arsenic), oxidative stress, and finally atmospheric stresses (air pollution, radiation and climate change). Hope, this book will be of greater use for the students and researchers, particularly Plant Breeders and Biotechnologists as well as the Botanists, to understand the injury and tolerance mechanisms, and subsequently improvement of crop genotypes for abiotic stresses.

The rapid population growth and the increase in the per capita income, especially in the group of emerging countries referred to as BRIC countries (Brazil, Russia, India, China and South Africa) has created huge pressure for the expansion of the agricultural growing area and the crop yields to meet the rising demand. As a result, many areas that have been considered marginal for growing crops, due to their low fertility, drought, salinity, and many other abiotic stresses, have now been incorporated in the production system. Additionally, climate change has brought new challenges to agriculture to produce food, feed, fiber and biofuels. To cope with these new challenges, many plant breeding programs have reoriented their breeding scope to stress tolerance in the last years. The authors of this book have collected the most recent advances and discoveries applied to breeding for abiotic stresses in this book, starting with new physiological concepts and breeding methods, and moving on to discuss modern molecular biological approaches geared to the development of improved cultivars tolerant to most sorts of abiotic stress. Written in an easy to understand style, this book is an excellent reference work for students, scientists and farmers interested in learning how to breed for abiotic stresses scenarios, presenting the state-of-the-art in plant stresses and allowing the reader to develop a greater understanding of the basic mechanisms of tolerance to abiotic stresses and how to breed for them.

The discipline of plant breeding has undergone transformation due to the assimilation of the rapid developments in molecular biology. The existing books on plant breeding deal mainly with the classical approaches, while specialized books on molecular approaches usually lack discussion of the classical methods. The book Plant Breeding for 21st Century attempts to present the complete picture of plant breeding ranging from the classical to the molecular approaches applied to crop improvement. The book is divided into four sections: Classical Plant Breeding, Transgenic technology, Molecular Markers, and Miscellaneous. The first section deals with the classical plant breeding and is divided into eight chapters. The second section has four chapters and describes transgenic technology. The third section discusses various aspects of molecular markers and is spread over three chapters. The final section has a single chapter dealing with variety release, seed multiplication and intellectual property rights. This book is designed primarily for graduate students, viz., B.Sc. agriculture and B.Sc. science students with botany as one of the subjects, who would get their first exposure to plant breeding. It would also be useful for the post-graduate students, especially in botany, and to teachers of the subject. The book is written in simple and easy to understand language. Illustrations and photographs have been provided wherever they were expected to facilitate comprehension of the subject under discussion.
