This book was released on 1996 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: An initial selection for nitrogen fixation was made from 77 genotypes of common bean (Phaseolus vulgaris) adapted to Goias state, Brazil, comparing them with control genotypes with know symbiotic capacity. After several selections, the outstanding genotypes for nitrogen fixation produced 1314 kg/ha (almost three times the Brazilian average), but the treatment with mineral nitrogen was superior, suggesting the necessity of a breeding project for nitrogen fixation. Two genotypes were selected based on their capacity to fix nitrogen, productivity without nitrogen fertilizers, adaptability to Goias state and other agronomic characteristics. The two parents were evaluated in semi-controlled conditions for symbiotic capacity. The genotype WBR2255 showed better symbiotic efficiency, nodule dry weight, weight per nodule, later nodule senescence and greater tolerance to mineral nitrogen in the latter stages of growth than A295.

Available in PDF, EPUB and Kindle. Book excerpt: Common bean (Phaseolus vulgaris L.) is an important legume for human consumption and has an important role in cropping systems as a rotational crop. Improving the sustainability in agriculture is necessary for meeting the food demands of a growing global population while lessening the environmental impact of cropping systems. Developing efficient methods of improving host-plant resistance to dry bean anthracnose (Colletotrichum lindemuthianum) and the symbiotic nitrogen fixation ability (SNF) can enhance the sustainability of common bean as a food crop. A QTL study with the black bean cultivar 'TU', known to possess the C. lindemuthianum race 109 resistance gene Co-5, was conducted to develop molecular markers to deploy in the MSU Dry Bean Breeding Program. Resistance to anthracnose was investigated in an F2 population developed from a cross between 'B19504' (a susceptible breeding line) and TU. 25 SNPs were identified between 6.84 and 24.62 Mb on linkage group 07. Improving SNF in common bean requires a method of efficiently evaluating breeding lines for the trait. Predictive models were developed from remote sensing-derived vegetation indices and machine learning algorithms to assess their ability to accurately and reliably estimate percent nitrogen derived from the atmosphere. A Random Forest model developed to predict nitrogen derived from the atmosphere (Ndfa) using yield and remote sensing (RS) data resulted in an average accuracy of r = 0.54. This model is promising in low nitrogen trials as an early selection tool to identify lines with higher SNF ability. Two prediction models for yield as an indirect indicator of SNF were developed using stepwise general linear modeling (StepwiseGLM) and Bayesian regularized artificial neural network (BRNeural Network) were determined to be accurate and reliable (StepwiseGLM r = 0.64; BRNeural Network r = 0.65). These models are promising in low nitrogen trials as an early selection tool to identify lines with higher SNF ability.

Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.
Download or read book Enhancement of Biological Nitrogen Fixation of Common Bean in Latin America written by F.A. Bliss and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common bean (Phaseolus vulgaris L.) is the most important pulse crop in Latin America, as well as in large parts of Asia and Africa. It is particularly important due to its ability, in symbiosis with Rhizobium bacteria, to fix atmospheric nitrogen and due to its high nutrient value. Incorporating contributions from plant breeders, microbiologists, plant physiologists and soil scientists, this volume reports the results of an FAO/IAEA Coordinated Research Programme (1985--1991), whose main objective was to enhance yield and biological nitrogen fixation in common bean by reducing its reliance on soil and fertilizer nitrogen. The volume will be invaluable to scientists working on biological nitrogen fixation and legume production.
Download or read book Genetic Resources of Phaseolus Beans written by Paul Gepts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: The period following the second world war has witnessed an expanding commitment to incr~ased food production in tropical countries. Public and private initiatives at the national and international levels have led to the creation of programs geared specifically towards the improvement of food crops in tropical conditions. Examples of this increased commitment are the network of international agricultural research centers and numerous bilateral aid projects. As a consequence, crop improvement has become a truly worldwide endeavor, relying on an international network of institutions and collaborators. This holds also for Phaseolus beans. Following the discovery of the Americas, Phaseolus beans became distributed on all six continents. Yet, until not so long ago, most of the research on Phaseolus improvement took place in developed countries. In recognition of the nutritional importance of Phaseolus beans in developing countries, this has changed considerably in the last years, principally perhaps through the activities of the Centro Internacional de Agricultura Tropical (CIAT) and the International Board for Plant Genetic Resources (IBPGR). Consequently, the scope of the research on Phaseolus has broadened considerably and the number of Phaseolus researchers is larger than ever before.

Download or read book Phaseolus Vulgaris written by Rocío Campos Vega and published by . This book was released on 2018 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Year of Pulses celebrated in 2016 magnified the public focus and consumer perception on human health, environmental aspects, crop production and novel product development benefits of pulses. The gluten-free and plant protein movements have also increased interest in pulse utilization. The common dry bean (Phaseolus vulgaris L.) among pulses is the most economically and widest ecologically adapted crop species used for food by large populations. Nowadays, dry beans top the list of pulse crops accounting on average for ~38 and 32% of global pulse growing area and production, respectively. Protein production from kidney beans requires about 18, 12, 10, 10 and 9 times less land, fertilizer, pesticide, water and fuel, respectively compared to producing the same amount of protein from beef.This book focuses on breeding aspects including new cultivars, production and post-harvest practices, and investigations that can lead to the development of high quality grain and functional foods, and nutraceutical products from beans. It also provides an overview of the crop management practices, technology progress and impacts favoring the best possible clean and sustainable crop production. Bean breeding is highlighted form the European perspective including the preservation/conservation of local gene pools. Bean production and quality improvement is a continuous process, particularly in major bean producing and consuming countries. The socioeconomic impact is considerable in countries where beans are traditionally part of the staple daily diet. However, application of novel technologies in improving nitrogen fixation, integrated disease management, and post-harvest storage ensures sustainable bean production and quality. The quality of bean types close to the site of its original domestication provides an outlook on their resilience and potential as a genetic resource and future food products. Current knowledge of bean health benefits, bioactive compounds, bioactive peptides and phenolics are important for development of novel functional foods. Beans can be used in many forms; as a natural coagulant, in metabolic disease prevention and other common bean-based food products, where their current market availability is explored. The multiple attributes of beans including cost, sustainability, commercial availability in varied forms and types ensure its extensive and expanding use in the development of healthy eating habits that can reduce healthcare and societal costs. This book should give plant scientists, nutritionists, health professionals, chemists and industry professionals interested in beans useful and up-to-date information to advance the field.
