Physiological Breeding I Interdisciplinary Approaches To Improve Crop Adaptation

This book covers different physiological processes, tools, and their application in crop breeding. Each chapter emphasizes on a specific trait/physiological process and its importance in crop, their phenotyping information and how best it can be employed for crop improvement by projecting on success stories in different crops. It covers wide range of physiological topics including advances in field phenotyping, role of endophytic fungi, metabolomics, application of stable isotopes, high throughput phenomics, transpiration efficiency, root phenotyping and root exudates for improved resource use efficiency, cuticular wax and its application, advances in photosynthetic studies, leaf spectral reflectance and physiological breeding in hardy crops like millets. This book also covers the futuristic research areas like artificial intelligence and machine learning. This contributed volume compiles all application parts of physiological tools along with their advanced research in these areas, which is very much need of the hour for both academics and researchers for ready reference. This book will be of interest to teachers, researchers, climate change scientists, capacity builders, and policy makers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, physiology, botany, ecology, and environmental sciences. National and international agricultural scientists will also find this a useful resource.

Plants are subjected to numerous environmental stresses, which can be classified into two broad areas: abiotic and biotic stresses. While the first is considered the damage done to an organism by other living organisms, the latter occurs as a result of a negative impact of non-living factors on the organisms. In this scenario, the current most accepted opinion of scientists is that both biotic and abiotic factors in nature and agroecosystems are affected by climate change, which may lead to significant crop yield decreases worldwide. We should take into consideration not only this environmental concern but also the fact that 20 years from now the earth's population will need 55% more food than it can produce now. Therefore, it is crucial to address such concerns and bring about possible solutions to future plant stress-related outcomes that might affect global agriculture. This book intends to provide the reader with a comprehensive overview of both biotic and abiotic stresses through 10 chapters that include case studies and literature reviews about these topics. There will be a particular focus on understanding the physiological, biochemical, and molecular changes observed in stressed plants as well as the mechanisms underlying stress tolerance in plants.

Crop Physiology: Case Histories of Major Crops updates the physiology of broad-acre crops with a focus on the genetic, environmental and management drivers of development, capture and efficiency in the use of radiation, water and nutrients, the formation of yield and aspects of quality. These physiological process are presented in a double context of challenges and solutions. The challenges to increase plant-based food, fodder, fiber and energy against the backdrop of population increase, climate change, dietary choices and declining public funding for research and development in agriculture are unprecedented and urgent. The proximal technological solutions to these challenges are genetic improvement and agronomy. Hence, the premise of the book is that crop physiology is most valuable when it engages meaningfully with breeding and agronomy. With contributions from 92 leading scientists from around the world, each chapter deals with a crop: maize, rice, wheat, barley, sorghum and oat; quinoa; soybean, field pea, chickpea, peanut, common bean, lentil, lupin and faba bean; sunflower and canola; potato, cassava, sugar beet and sugarcane; and cotton. A crop-based approach to crop physiology in a G x E x M context Captures the perspectives of global experts on 22 crops

This edited volume provides state-of–the-art overview of abiotic stress responses and tolerance mechanisms of different legume crops viz., chickpea, mung bean, lentil, black gram, cowpea, cluster bean, soybean and groundnut. Legumes play an important role in human nutrition and soil health through fixation of nitrogen. Legume production and productivity are vulnerable to different abiotic stresses. A proper understanding about the physiological and molecular basis of the legume crops is essential for genetic improvement of abiotic stress tolerance. This book consists of 15 chapters covering physiological and biochemical basis, molecular physiology, molecular breeding, genetics, genomics, transgenics, epigenetics of drought, saline, high temperature and nutrient deficiency stresses, and the role of microRNAs in abiotic stress tolerance. This volume offers new perspectives in legume crop abiotic stress management, and is useful for various stakeholders, including post graduates students, scientists, environmentalists and policymakers.

Identification of desirable genotypes with traits of interest is discernible for making genetic improvement of crop plants. In this direction, screening of a large number of germplasm for desirable traits and transfer of identified traits into agronomic backgrounds through recombination breeding is the common breeding approach. Although visual screening is easier for qualitative traits, its use is not much effective for quantitative traits and also for those, which are difficult to score visually. Therefore, it is imperative to phenotype the germplasm accessions and breeding materials precisely using high throughput phenomics tools for challenging and complex traits under natural, controlled and harsh environmental conditions. Realizing the importance of phenotyping data towards identification and utilization of a germplasm as donors, global scientific community has exerted increased focus on advancing phenomics in crop plants leading to development of a number of techniques and methodologies for screening of agronomic, physiological, and biochemical traits. These technologies have now become much advanced and entered the era of digital science. This book provides exhaustive information on various aspects related to phenotyping of crop plants and offers a most comprehensive reference on the developments made in traditional and high throughput phenotyping of agricultural crops.
