This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorghum (Sorghum bicolor (L.) Moench) is one of the hardiest crop to abiotic stresses compared with other grain crops. However early stage chilling, terminal heat and drought stress are three most damaging abiotic stresses that have limited sorghum productivity in the US Great plains and other locations having similar environmental conditions. Three studies were conducted with an overall goal aimed at increasing grain sorghum's resilience to harsh climatic conditions. In the first study, four promising chilling stress tolerant sorghum advanced breeding lines, a known early stage chilling tolerant Chinese landrace (Shan Qui Red - SQR) and a susceptible US elite cultivar (RTx430) as checks were assessed for chilling tolerance during emergence and early growth under field and controlled environments. Aerial phenotyping using unmanned aircraft systems (UAS) fitted with multispectral camera was used to capture reflectance-based vegetation indices (NDVI and NDRE) in field experiments. Some advanced breeding lines with superior agronomic background also recorded significantly better emergence, seedling growth and vigor compared to SQR under chilling conditions. Aerial phenotyping indices from images taken between 30 and 60 days after emergence were consistently correlated with destructive measurements under early plantings, indicating their effectiveness in differentiating chilling responses. Second study was conducted to understand physiological mechanisms inducing heat stress resilience in sorghum during flowering. A diverse set of sorghum inbreds and selected hybrids were tested under greenhouse, growth chamber facilities and field conditions. A highly conserved early-morning-flowering mechanism was observed across all the inbreds and hybrids, with the peak anthesis wherein >90% of florets completed flowering within 30 min after dawn. The conserved response was consistent even under drought stress and heat stress exposure imposed at different times of the day. Our findings report a novel heat escaping early-morning-flowering mechanism effectively employed by sorghum to minimize heat stress impact at anthesis. Another experiment with sequential increase in daytime temperature treatments suggest heat stress induced loss in pollen viability to be a key factor resulting in reduced seed-set and grain yield. The findings suggest heat stress could have a greater impact on post-pollen germination processes such as fertilization, embryo formation and development. We identified a heat tolerant genotype "Macia" which appears to be a promising donor for developing improved heat tolerant sorghum hybrids. In the third study, a bi-parental recombinant inbred lines (RILs) mapping population developed from elite post flowering drought susceptible cultivar (RTx430) and a known drought tolerant cultivar (SC35) were evaluated under wide spectrum of environments and moisture conditions. Several novel and major QTL for grain yield, panicle neck diameter, effective quantum yield of photosystem II and chlorophyll content were identified. The genomic regions and the candidate genes within these regions can potentially help in improving source and sink dynamics in sorghum under diverse environments. The findings from these studies will complement ongoing efforts in developing future sorghum with enhanced resilience to different abiotic stresses that continue to limit sorghum productivity.

Book Synopsis Genetic Enhancement of Rabi Sorghum by : Sanjana Reddy
Download or read book Genetic Enhancement of Rabi Sorghum written by Sanjana Reddy and published by Academic Press. This book was released on 2015-05-28 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic Enhancement of Rabi Sorghum – Adapting the Indian Durras presents both the historical background and the recent research done in breeding this important world crop for more global production. Its chapters cover topics in origin and taxonomy, morphology and breeding behavior, genetics, and cytogenetics, also looking at production, nutrition, and alternate uses. The durra race is Ethiopian in origin and its introgression with wild forms permitted adaptation to drier conditions. These have migrated and adapted to the currently known crop that is cultivated in the winter season and commonly called rabi sorghums. Grown under receding soil moisture conditions, rabi sorghums have tolerance to abiotic stresses apart from biotic stresses, unlike the rainy sorghums that are grown widely in the world. However, they must be more resilient to rapid changes in climate, for example. The variability from winter sorghums is being introgressed into rainy sorghums. With the yield plateaus reached and sorghum gaining importance as a food crop, this book will be of importance to those studying durras and their breeding. Presents both the historical background and most recent research done in breeding rabi sorghum for more global production Provides information on the adaptation of the crop and the ways it has migrated to the currently known crop, which is cultivated in winter season and commonly called as rabi sorghum Explores strategies for resilience as the crop must be prepared to withstand rapid and varying changes in climate

Book Synopsis Omics Approach to Manage Abiotic Stress in Cereals by : Aryadeep Roychoudhury
Download or read book Omics Approach to Manage Abiotic Stress in Cereals written by Aryadeep Roychoudhury and published by Springer Nature. This book was released on 2022-05-30 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: The edited book highlights various emerging Omics tools and techniques that are currently being used in the analysis of responses to different abiotic stress in agronomically important cereals and their applications in enhancing tolerance mechanism. Plants are severely challenged by diverse abiotic stress factors such as low water availability (drought), excess water (flooding/ waterlogging), extremes of temperatures (cold, chilling, frost, and heat), salinity, mineral deficiency, and heavy metal toxicity. Agronomically important cereal crops like Rice, Wheat, Maize, Sorghum, Pearl Millet, Barley, Oats, Rye, Foxtail Millets etc. that are the major sources of food material and nutritional components for human health are mostly exposed to abiotic stresses during the critical phases of flowering and grain yield. Different Omics platforms like genomics, transcriptomics proteomics, metabolomics and phenomics, in conjunction with breeding and transgenic technology, and high throughput technologies like next generation sequencing, epigenomics, genome editing and CRISPR-Cas technology have emerged altogether in understanding abiotic stress response and strengthening defense and tolerance mechanism of different cereals. This book is beneficial to different universities and research institutes working with different cereal crops in the areas of stress physiology, stress-associated genes and proteins, genomics, proteomics, genetic engineering, and other fields of molecular plant physiology. The book can also be used as advanced textbook for the course work of research and master’s level students. It will be of use to people involved in ecological studies and sustainable agriculture. The proposed book bring together the global leaders working on environmental stress in different cereal crops and motivate scientists to explore new horizons in the relevant areas of research.

Book Synopsis Phenotyping for Plant Breeding by : Siva Kumar Panguluri
Download or read book Phenotyping for Plant Breeding written by Siva Kumar Panguluri and published by Springer Science & Business Media. This book was released on 2013-10-09 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant phenotyping is the thorough assessment of plant traits such as growth, development, adaptation, yield, quality, tolerance, resistance, architecture, and the basic measurement of individual quantitative parameters that form the basis for understanding of traits. Genetic approaches to understand plant growth and development have always benefitted from phenotyping techniques that are simple, rapid and measurable in units. The forward genetics approach is all about understanding the trait inheritance using the phenotypic data and in most cases it is the mutant phenotypes that formed the basis for understanding of gene functions. With rapid advancement of genotyping techniques, high throughput genotyping has become a reality at costs people never imagined to be that low, but the phenotypic methods did not receive same attention. However, without quality phenotyping data the genotyping data cannot be effectively put to use in plant improvement. Therefore efforts are underway to develop high-throughput phenotyping methods in plants to keep pace with revolutionary advancement in genotyping techniques to enhance the efficiency of crop improvement programs. Keeping this in mind, we described in this book the best phenomic tools available for trait improvement in some of the world’s most important crop plants.
Book Synopsis Genomic Designing of Climate-Smart Cereal Crops by : Chittaranjan Kole
Download or read book Genomic Designing of Climate-Smart Cereal Crops written by Chittaranjan Kole and published by Springer Nature. This book was released on 2020-02-28 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights modern methods and strategies to improve cereal crops in the era of climate change, presenting the latest advances in plant molecular mapping and genome sequencing. Spectacular achievements in the fields of molecular breeding, transgenics and genomics in the last three decades have facilitated revolutionary changes in cereal- crop-improvement strategies and techniques. Since the genome sequencing of rice in 2002, the genomes of over eight cereal crops have been sequenced and more are to follow. This has made it possible to decipher the exact nucleotide sequence and chromosomal positions of agroeconomic genes. Most importantly, comparative genomics and genotyping-by-sequencing have opened up new vistas for exploring available biodiversity, particularly of wild crop relatives, for identifying useful donor genes.
Book Synopsis Crop Stress and its Management: Perspectives and Strategies by : B. Venkateswarlu
Download or read book Crop Stress and its Management: Perspectives and Strategies written by B. Venkateswarlu and published by Springer Science & Business Media. This book was released on 2011-11-22 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crops experience an assortment of environmental stresses which include abiotic viz., drought, water logging, salinity, extremes of temperature, high variability in radiation, subtle but perceptible changes in atmospheric gases and biotic viz., insects, birds, other pests, weeds, pathogens (viruses and other microbes). The ability to tolerate or adapt and overwinter by effectively countering these stresses is a very multifaceted phenomenon. In addition, the inability to do so which renders the crops susceptible is again the result of various exogenous and endogenous interactions in the ecosystem. Both biotic and abiotic stresses occur at various stages of plant development and frequently more than one stress concurrently affects the crop. Stresses result in both universal and definite effects on plant growth and development. One of the imposing tasks for the crop researchers globally is to distinguish and to diminish effects of these stress factors on the performance of crop plants, especially with respect to yield and quality of harvested products. This is of special significance in view of the impending climate change, with complex consequences for economically profitable and ecologically and environmentally sound global agriculture. The challenge at the hands of the crop scientist in such a scenario is to promote a competitive and multifunctional agriculture, leading to the production of highly nourishing, healthy and secure food and animal feed as well as raw materials for a wide variety of industrial applications. In order to successfully meet this challenge researchers have to understand the various aspects of these stresses in view of the current development from molecules to ecosystems. The book will focus on broad research areas in relation to these stresses which are in the forefront in contemporary crop stress research.

Download or read book Sorghum in the 21st Century: Food – Fodder – Feed – Fuel for a Rapidly Changing World written by Vilas A. Tonapi and published by Springer Nature. This book was released on 2021-01-04 with total page 932 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorghum is the most important cereal crop grown in the semi-arid tropics (SAT) of Africa, Asia, Australia and Americas for food, feed, fodder and fuel. It is the fifth most important cereal crop globally after rice, wheat, maize and barley, and plays a major role in global food security. Sorghum is consumed in different forms for various end-uses. Its grain is mostly used directly for food purposes. After the release of the proceedings of two international symposia in the form of books “Sorghum in Seventies” and “Sorghum in Eighties”, global sorghum research and development have not been documented at one place. Of course, few books on sorghum have been released that focus on specific issues/research areas, but comprehensive review of all aspects of recent development in different areas of sorghum science has not been compiled in the form a single book. This book is intended to fill in a void to bridge the gap by documenting all aspects of recent research and development in sorghum encompassing all the progress made, milestones achieved across globe in genetic diversity assessment, crop improvement and production, strategies for high yield, biotic and abiotic stress resistance, grain and stover quality aspects, storage, nutrition, health and industrial applications, biotechnological applications to increase production, including regional and global policy perspectives and developmental needs. This book will be an institutional effort to compile all the latest information generated in research and development in sorghum across the globe at one place.
Book Synopsis Molecular Breeding in Wheat, Maize and Sorghum by : Mohammad Anwar Hossain
Download or read book Molecular Breeding in Wheat, Maize and Sorghum written by Mohammad Anwar Hossain and published by CABI. This book was released on 2021-06-30 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global population is projected to reach almost 10 billion by 2050, and food and feed production will need to increase by 70%. Wheat, maize and sorghum are three key cereals which provide nutrition for the majority of the world's population. Their production is affected by various abiotic stresses which cause significant yield losses. The effects of climate change also increase the frequency and severity of such abiotic stresses. Molecular breeding technologies offer real hope for improving crop yields. Although significant progress has been made over the last few years, there is still a need to bridge the large gap between yields in the most favorable and most stressful conditions.
