Book Description
The creation of homozygous parental lines for hybrid development is one of the key components of commercial maize breeding programs. It usually takes up to 6 to 7 generations of selfing to obtain homozygous inbreds from the initial cross using the conventional pedigree method. Using doubled haploid (DH) method, concurrent fixation of all the genes covering entire chromosomes is possible within a single generation. For generation of DH lines, haploids are generated first by several means such as in-vitro method using tissue culture technique and in-vivo method using the haploid inducer (HI) lines. Of which, tissue culture-based methods have shown little promise for large-scale DH production as it needs good infrastructures and technical requirements. In contrast, inducer-based method provides more optimistic solutions for large-scale DH lines production. Due to its rapidity, DH technology is now being adopted in many countries including India for reducing the breeding cycle.

Book Description
This book is open access under a CC BY 4.0 license. By 2050, human population is expected to reach 9.7 billion. The demand for increased food production needs to be met from ever reducing resources of land, water and other environmental constraints. Rice remains the staple food source for a majority of the global populations, but especially in Asia where ninety percent of rice is grown and consumed. Climate change continues to impose abiotic and biotic stresses that curtail rice quality and yields. Researchers have been challenged to provide innovative solutions to maintain, or even increase, rice production. Amongst them, the ‘green super rice’ breeding strategy has been successful for leading the development and release of multiple abiotic and biotic stress tolerant rice varieties. Recent advances in plant molecular biology and biotechnologies have led to the identification of stress responsive genes and signaling pathways, which open up new paradigms to augment rice productivity. Accordingly, transcription factors, protein kinases and enzymes for generating protective metabolites and proteins all contribute to an intricate network of events that guard and maintain cellular integrity. In addition, various quantitative trait loci associated with elevated stress tolerance have been cloned, resulting in the detection of novel genes for biotic and abiotic stress resistance. Mechanistic understanding of the genetic basis of traits, such as N and P use, is allowing rice researchers to engineer nutrient-efficient rice varieties, which would result in higher yields with lower inputs. Likewise, the research in micronutrients biosynthesis opens doors to genetic engineering of metabolic pathways to enhance micronutrients production. With third generation sequencing techniques on the horizon, exciting progress can be expected to vastly improve molecular markers for gene-trait associations forecast with increasing accuracy. This book emphasizes on the areas of rice science that attempt to overcome the foremost limitations in rice production. Our intention is to highlight research advances in the fields of physiology, molecular breeding and genetics, with a special focus on increasing productivity, improving biotic and abiotic stress tolerance and nutritional quality of rice.

Book Description
This edited book highlights the gravity and efficacy of next-generation breeding tools for the enhancement of stress-resilience in cereals, especially in the context of climate change, pests, diseases, and abiotic stresses. The content of the book helps in understanding the application of emerging genetic concepts and neoteric genomic approaches in cereal breeding. It collates all the latest information about enhancing the stress resilience in cereal crops for overcoming food security issues. Cereals have predominantly been used as a staple food since time immemorial and contribute more than 50% of the caloric requirement of the global population. However, in cereals, the yield losses due to various stresses are very high, considering the crop growth stage and stress sensitivity. Therefore, to feed and nourish the generations in the era of climate change, it is imperative to develop stress-resilient cereal cultivars. This book explores newly developed next-generation breeding tools, viz., genome-wide association studies, genomic prediction, genome editing, and accelerated generation advancement methodologies, which revealed promising outcomes by enhancing the stress resilience in cereals with yield potential. This book is useful for postgraduate students specializing in plant breeding, plant stress physiology, plant genomics, agriculture, and agronomy. It is of immense value to scientific community involved in teaching, research, and extension activities related to cereal cultivation.

Book Description
Climate change is expected to have a drastic impact on agronomic conditions including temperature, precipitation, soil nutrients, and the incidence of disease pests, to name a few. To face this looming threat, significant progress in developing new breeding strategies has been made over the last few decades. The first volume of Genomics and Breeding for Climate-Resilient Crops presents the basic concepts and strategies for developing climate-resilient crop varieties. Topics covered include: conservation, evaluation and utilization of biodiversity; identification of traits, genes and crops of the future; genomic and molecular tools; genetic engineering; participatory and evolutionary breeding; bioinformatics tools to support breeding; funding and networking support; and intellectual property, regulatory issues, social and political dimensions. ​

Book Description
"An indispensable source for researchers, teachers, and graduate and postgraduate students interested in mutation breeding and genetic engineering. It introduces readers to contemporary knowledge and state-of-the-art technologies in the field of mutation breeding, including fundamental mechanisms and applications. . . . It will provide new directions, and avenues for enhancement of food security and food quality by using the latest techniques for the 'mutation as breeding' approach." - From Prof. Jameel M. Al-Khayri, King Faisal University, Saudi Arabia This comprehensive three-volume set book aims to help combat the challenge of providing enough food for the world by the use of advanced genetic processes to improve crop production, both in quantity and quality. Volume 1: Mutagenesis and Crop Improvement discusses mutagenesis, cytotoxicity, and crop improvement, covering the processes, mutagenic effectiveness, and mechanisms. The volume emphasizes the improvement of agronomic characteristics by manipulating the genotype of plant species, resulting in increased productivity. Volume 2: Revolutionizing Plant Biology covers the use of mutagenesis and biotechnology to explore the variability of mutant genes for crop improvement. The chapters deal with in-vitro mutagenesis to exploit the somaclonal variations induced in cell culture and highlight the importance of in-vitro mutagenesis in inducing salt resistance, heat resistance, and drought resistance. Volume 3: Mechanisms for Genetic Manipulation of Plants and Plant Mutants reviews the genetic engineering techniques used to mutate genes and to incorporate them into different plant species of cereals, pulses, vegetables, and fruits. Also discussed are the principles of genetic engineering by which desired genes can be transferred from plants to animals to microorganisms and vice versa.
