Screening Methods and Sources of Resistance to Rust and Late Spot of Groundnut


Book Description

Ferrugem e mancha foliar tardia do amendoim: metodos da avaliacao e fontes da resistencia. Ferrugem e mancha foliar tardia sao as doencas mais serias do amendoim pelo mundo inteiro, e podem causar severas perdas no rendimento, especialmento quando ocorrem juntamente. Esse boletim descreve metodos da avaliacao simples e efetivos para identificar genotipos com resistencia a essas doencas. Foram discutidos usando a escala 1-9, producao do inoculo, sementeira e inoculacao dos genotipos, avaliacao das doencas no campo. Esses metodos foram utilisados durante 1977-89 para avaliar mais de 12000 genotipos de amendoim que pertencem a ICRISAT de varias partes do mundo. Seguras fontes da resistencia a ferrugem e mancha foliar tardia foram identificadas e estao aqui catalogadas - 124 linhas resistentes a ferrugem, 54 linhas resistentes a mancha foliar tardia e 29 linhas com uma resistencia combinada. Para os que necessitam uma mais detalhada informacao sobre es especificos aspectos das doencas, uma extensiva bibliografia esta tambem introduzida.

Genetics, Genomics and Breeding of Peanuts


Book Description

Peanut, an amphidiploid, is an important food and oil crop and has an interesting evolutionary history. This book provides a glimpse of the advances in genetic resources and genomics research of peanut made during the last decade. It contains an overview of germplasm, advances in genetic and genomic resources, genetic and trait mapping, proteomic and transcriptomic analyses, functional and comparative genomics studies, and molecular breeding applications. This book should prove useful to students, teachers, and young researchers as a ready reference to the latest information on peanut genetics and genomics.




Peanuts


Book Description

Peanuts: Genetics, Processing, and Utilization (Oilseed Monograph) presents innovations in crop productivity and processing technologies that help ensure global food security and high quality peanut products. The authors cover three central themes, modern breeding methods for development of agronomic varieties in the U.S., China, West Central Africa, and India, enhanced crop protection and quality through information from the peanut genome sequence, and state-of-the-art processing and manufacturing of products in market environments driven by consumer perception, legislation, and governmental policy. - Discusses modern breeding methods and genetically diverse resources for the development of agronomic varieties in the U.S., China, India, and West Central Africa - Provides enhanced crop protection and quality through the application of information and genetic tools derived from analysis of the peanut genome sequence - Includes state-of-art processing and manufacture of safe, nutritious, and flavorful food products




The Peanut Genome


Book Description

This book presents the current state of the art in peanut genomics, focusing particularly on the latest genomic findings, tools and strategies employed in genome sequencing, transcriptomes and analysis, availability of public and private genomic resources, and ways to maximize the use of this information in peanut breeding programs. Further, it demonstrates how advances in plant genomics can be used to improve crop breeding. The peanut or groundnut (Arachis hypogaea L. Millsp) is a globally important grain legume and oilseed crop, cultivated in over 100 countries and consumed in the form of roasted seeds, oil and confectionary in nearly every country on Earth. The peanut contributes towards achieving food and nutritional security, in addition to financial security through income generation; as such, it is also vital to the livelihood of the poor in the developing world. There have been significant advances in peanut research, especially in the last five years, including sequencing the genome of both diploid progenitors, and the availability of tremendous transcriptome resources, large-scale genomic variations that can be used as genetic markers, genetic populations (bi- and multiparent populations and germplasm sets), marker-trait associations and molecular breeding products. The immediate availability of the genome sequence for tetraploid cultivated peanuts is the most essential genomic resource for achieving a deeper understanding of peanut traits and their use in breeding programs.




Phenotyping for Plant Breeding


Book Description

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.
