Landraces possess a very large genetic base in population structure and are dynamic populations of cultivated plants with historical origin, distinct identity, and without any formal crop improvement. They are often genetically diverse, locally adapted, and associated with traditional farming systems. Resistance genes to biotic and abiotic stress factors, which are especially diversified in landraces, are of great interest to plant breeders, faced with global climate challenge. In addition, gene pools made of different landraces grown in different ecological conditions can be used for wheat breeding to enhance quality; yield and other desirable agricultural parameters. An estimated 75% of the genetic diversity of crop plants was lost in the last century due to the replacement of high yielding modern varieties. There is, thus, an urgent need to preserve existing species, not only for posterity but also as a means to secure food supply for a rising world population. In this book, we provide an overview of wheat landraces with special attention to genetic diversities, conservation, and utilization.

A considerable change in climate at a global level will impact the vegetable cultivation and agriculture as a whole; subsequently affecting the world's food supply. Climate change per se is not necessarily harmful; the problems arise from extreme events that are difficult to predict (erratic rainfall patterns and unpredictable high and low temperatures), and consequently reduce crop productivity. Vegetables are in general more succulent (have 90% water) and are more sensitive to climatic vagaries. Sudden changes in temperature coupled with irregular precipitation at any phase of crop growth can affect the normal growth, flowering, pollination, fruit setting, fruit development and fruit ripening can decrease the yield. The irregular precipitation can also affect the soil salinity and is a major challenge in many vegetable growing areas. To mitigate the harmful impact of climatic change there is a urgent need to develop adequate adaptation strategies for adverse effect of climate change and the preference should be given on development of heat, cold, drought, flood and salinity stress tolerant genotypes along with climate proofing through conventional and non-conventional breeding techniques. Available evidence shows that there is a high probability of increase in the frequency and intensity of climate related natural hazards due to climate change and hence increases the potential threat due to climate change related natural disasters in the world. This book (Volume- I) will be basically useful for the researchers and postgraduate students with current challenges and mitigation strategies for increasing vegetable production under a changing climate.

Dokuchaev carried out most of his research in Ukraine. His student and friend, Volodymyr Vernadsky, went on to create trans-disciplinary environmental sciences and the concept of Earth as a living organism, famously taken up by James Lovelock. That spring of ideas still flows and the researches captured in this volume are relevant to present-day problems, and not only in Ukraine. Soils have always been under stress but, in the Anthropocene, mankind is in the driving seat. As a sequel to Soil Science Working for a Living: Applications of soil science to present-day problems, we consider issues of policy as well as soil genesis, attributes and functions in various environments, natural and man-made. We consider human impacts on the soil cover through its use and misuse, highlight methods of research and assessment of soil quality, and the threats of soil degradation. The distinguished contributors also describe and propose various options for evaluation and remediation of degraded soils, drawing on the latest methods of modelling and cartography as well as long-term field experiments and long experience. The book will be invaluable to researchers and practitioners in soil science including graduate and post-graduate education, academics and professionals.

Vegetable production in our country is still dominated by the locally available genotypes or open-pollinated varieties, which are low-yielding and susceptible to various insect pest and diseases. This is mainly due to farmers' ignorance and poor extension activities. Hence, there is a need to grow vegetable hybrids for increasing production and productivity along with quality. Development or hybrids from the existing ones play a pivotal role not only for increasing the productivity but also helps to combat several problems faced by farmers. Thus to achieve these objectives, the authors have made an effort to give information for development of vegetables hybrid both theoretical and practical aspects in the form of book entitled, Heterosis Breeding in Vegetable Crops. This publication contains 17 s in two sections. The first section includes 10 s related to theoretical aspect of heterosis. viz. i Introduction to Heterosis ii Basis of Heterosis iii Commercial Exploitation of Heterosis iv Reproduction, Pollen and Pollen Biotechnology v Population Improvement of Parents/Hybrids Varieties vi Genetic Purity Testing of Hybrids vii Hybrid Varieties Testing and Release Procedures in India viii Biotechnology and Vegetable Improvement xi Intellectual Property Right related Issues in Hybrid Technology and x Economics, Import and Export. Second section consists of practical aspect of hybrid seed production deals seven s, viz. xi Solanaceous Crops-tomato, brinjal, chilli and bell pepper, xii Malvaceous Crops-okra, xiii Cole crops-cabbage and cauliflower xiv Cucurbitaceous Crops-bitter gourd, bottle gourd, cucumber, muskmelon, watermelon, pumpkin, ridged and smooth gourd xv Root Crops-carrot. xvi Bulb Crops-onion and xvii Hints for Hybrid Cultivation. All the s cover references, illustrations and tables. The publication also contains characteristics of national released hybrids with colored photographs. This would be useful to teachers, scientists, students, extension workers, vegetable industry and farmers of this country.

Water pollution control has been a top environmental policy priority of the world's most developed countries for decades, and the focus of significant regulation and public and private spending. Yet, significant water quality problems remain, and trends for some pollutants are in the wrong direction. This book addresses the economics of water pollution control and water pollution control policy in agriculture, with an aim towards providing students, environmental policy analysts, and other environmental professionals with economic concepts and tools essential to understanding the problem and crafting solutions that can be effective and efficient. The book will also examine existing policies and proposed reforms in the developed world. Although this book addresses and has a general applicability to major water pollutants from agriculture (e.g., pesticides, pharmaceuticals, sediments, nutrients), it will focus on the sediment and nutrient pollution problem. The economic and scientific foundations for pollution management are best developed for these pollutants, and they are currently the top priorities of policy makers. Accordingly, the authors provide both highly salient and informative cases for developing concepts and methods of general applicability, with high profile examples such as the Chesapeake Bay, Lake Erie, and the Gulf of Mexico Dead Zone in the US; the Baltic Sea in Northern Europe; and Lake Taupo in New Zealand.

In A Theory of Environmental Leadership, Mark Manolopoulos draws on his original model of leading outlined in his cutting-edge book Following Reason to derive and develop the first properly systematic model of eco-leadership. Suppose humanity's relation with the Earth may be described in terms of leadership "stages" or modalities: once upon a time, the Earth led or ruled humanity, and now we humans rule or lead the Earth. When the Earth led, the Earth flourished; now that humankind leads, the Earth flounders - ecological crises multiply and intensify. However, there might be a third stage or modality of leadership: humanity leading for the Earth, leading in a way that allows the world, including humans, to re-flourish. What would be the nature of this truly environmental form of leadership? A Theory of Environmental Leadership identifies and critically analyzes the two basic and incompatible positions associated with the way we construe and interact with the non-human: anthropocentrism (human supremacism) and ecocentrism (ecological egalitarianism). By rigorously analyzing and leveraging this polarity, this book outlines an innovative theory of eco-leadership together with some of its confronting-but-necessary measures. Expansive and incredibly timely, A Theory of Environmental Leadership is ideal for a range of audiences, from scholars and students of environmental leadership studies to activists and policymakers. The book's remarkable clarity and engaging character also makes it suitable for the general public.

Abiotic and biotic stress factors, including drought, salinity, waterlog, temperature extremes, mineral nutrients, heavy metals, plant diseases, nematodes, viruses, and diseases, adversely affect growth as well as yield of crop plants worldwide. Plant growth-promoting microorganisms (PGPM) are receiving increasing attention from agronomists and environmentalists as candidates to develop an effective, eco-friendly, and sustainable alternative to conventional agricultural (e.g., chemical fertilizers and pesticide) and remediation (e.g., chelators-enhanced phytoremediation) methods employed to deal with climate change-induced stresses. Recent studies have shown that plant growth-promoting bacteria (PGPB), rhizobia, arbuscular mycorrhizal fungi (AMF), cyanobacteria have great potentials in the management of various agricultural and environmental problems. This book provides current research of biofertilizers and the role of microorganisms in plant health, with specific emphasis on the mitigating strategies to combat plant stresses.

Selenium plays a significant role in preventing certain types of cancer and cardiovascular diseases. The level of Selenium in the human body depends on its concentration in food. In turn, the content in vegetable crops is a function of the soil-plant system. There are many countries in the world with low Selenium content in the soil. The average daily human intake is thus limited through food chain. Analysis of Selenium status suggests that fortification of the soil substrate with Sodium Selenate, and foliar application to agricultural crops are both effective means of Selenium enrichment. Our intention for this publication is to present the possibilities of augmenting Selenium content by biofortification of soils and plants through differentiated nutrition. In the first part of the monograph, the results of Selenium supplementation in model vegetation experiments are presented. The next part of the monograph presents the results of foliar supplementation of Selenium in field conditions. This book is an outstanding reference source for plant breeders and researchers engaged in biofortification of horticulture crops. It is also beneficial to agricultural companies and other stakeholders.

The Bambara groundnut (BGN) or Vigna subterranea is an extremely hardy grain legume. As it produces reasonable yields even under conditions of drought and low soil fertility, it is also a climate-smart crop. Previously underutilized, BGN is the subject of growing interest among researchers and consumers for its balanced nutritional profile. Indigenous consumers of BGN report medicinal benefits from the plant; however, such knowledge is at risk of being lost with the urbanization and changing lifestyles of younger generations. To date, there is no comprehensive resource on the Bambara groundnut, despite market demand for plant proteins around the globe. Authored by scientists who have researched and developed patents using BGN, Bambara Groundnut: Utilization and Future Prospects aims to fill this gap. The text provides in-depth coverage on breeding, food and feed utilization, medicinal benefits and future research prospects. Drawing on both indigenous knowledge and cutting-edge research, Bambara Groundnut is the first book to fully explore the potential of this remarkable crop.

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), the spotted wing drosophila (SWD), is the most important pest affecting berry crop production worldwide. The global fresh fruit trade, coupled with the ability of the larvae to hide inside the fruit undetected until after transportation, facilitate their distribution. SWD is native to Asia, but is increasingly found in other regions: occurrences have been recorded in the Americas and Europe, and Africa, and the insects have the potential to adapt and become established in Oceania. Gathering the experiences of leading scientists in the management of D. suzukii around the globe, the book addresses D. suzukii monitoring; biological, chemical and cultural control; sterile insect technique (SIT); integrated pest management (IPM), and other control methods. It also discusses the use of drones, GPS, biotechnology, telemetry and other technological tools to make the management of this pest more efficient and accurate. As such, it is a valuable resource for scientists, professionals and students.

The editors have also compiled some advanced, outstanding texts that should be of benefit to graduate students in their research.

Blast is an important foliar disease that infects the majority of cereal crops like rice, finger millet, pearl millet, foxtail millet and wheat, and thus resulting in a huge economic impact. The pathogen is responsible for causing epidemics in many crops and commonly shifts to new hosts. Magnaporthe spp. is the most prominent cause of blast disease on a broad host range of grasses including rice as well as other species of poaceae family. To date, 137 members of Poaceae hosting this fungus have been described in Fungal Databases. This book provides information on all blast diseases of different cereal crops. The pathogen evolves quickly due to its high variability, and thus can quickly adapt to new cultivars and cause an epidemic in a given crop. Some of the topics covered here include historical perspectives, pathogen evolution, host range shift, cross-infectivity, and pathogen isolation, use of chemicals fungicides, genetics and genomics, and management of blast disease in different cereal crops with adoption of suitable methodologies.In the past two decades there have been significant developments in genomics and proteomics approaches and there has been substantial and rapid progress in the cloning and mapping of R genes for blast resistance, as well as in comparative genomics analysis for resolving delineation of Magnaporthe species that infect both cereals and grass species. Blast disease resistance follows a typical gene-for-gene hypothesis. Identification of new Avr genes and effector molecules from Magnaporthe spp. can be useful to understand the molecular mechanisms involved in the fast evolution of different strains of this fungal genus. Advances in these areas may help to reduce the occurrence of blast disease by the identification of potential R genes for effective deployment. Additionally, this book highlights the importance of blast disease that infects different cereal hosts in the context of climate change, and genomics approaches that may potentially help in understanding and applying new concepts and technologies that can make real impact in sustainable management of blast disease in different cereal crops.

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 edited volume 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.
