Available in PDF, EPUB and Kindle. Book excerpt: The protein molecule is the basic building block of every living entity. Its deficiency leads to restricted growth and development of individuals. Globally, such malnutrition is on the rise due to various reasons such as rapid population growth, stagnation of productivity, and ever-rising costs. Millions of people, especially in developing and under-developed countries, suffer from protein malnutrition and the only possible solution is to encourage farmers to grow high-protein food legume crops in their fields for domestic consumption. This, however, could be possible if farmers are provided with new cultivars with high yield, and resistance to major insects, diseases, and key abiotic stresses. The major food legume crops are chickpea, cowpea, common bean, groundnut, lentil, pigeonpea, and soybean. Predominantly, the legume crops are grown under a subsistence level and, therefore, in comparison to cereals and horticultural crops their productivity is low and highly variable. The crop breeders around the globe are engaged in breeding suitable cultivars for harsh and changing environments but success has been limited and not up to needs. With the recent development of new technologies in plant sciences, efforts are being made to help under-privileged farmers through breeding new cultivars which will produce more protein per unit of land area. In this book, the contributors analyze the constraints, review new technologies, and propose a future course of crop breeding programs in seven cold and warm season legume crops.

Book Synopsis The Host-pathogen Interaction and Breeding and Genetics of Resistance for Common Bacterial Blight of Common Bean (Phaseolus Vulgaris L.) Caused by Xanthomonas Campestris Pv. Phaseoli and X. C. Pv. Phaseoli Var. Fuscans by : Robert Wayne Duncan
Download or read book The Host-pathogen Interaction and Breeding and Genetics of Resistance for Common Bacterial Blight of Common Bean (Phaseolus Vulgaris L.) Caused by Xanthomonas Campestris Pv. Phaseoli and X. C. Pv. Phaseoli Var. Fuscans written by Robert Wayne Duncan and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Common bacterial blight (CBB) caused by Xanthomonas campestris pv. phaseoli Smith (Dye) (Xcp, synonym: X. axonopodis pv. phaseoli [Smith] Vauterin et al.) and X. c. pv. phaseoli var. fuscans (Burkholder) Starr & Burkholder (Xcpf, synonym: X. fuscans subsp. fuscans sp. nov.) is the most important bacterial disease of common bean (Phaseolus vulgaris L.). Host resistance is the best method of management for this seed-borne disease. The first objective of this research was a host-pathogen diversity study, where new Xcp and Xcpf genotypes associated with CBB in Wisconsin were identified. These new genotypes, along with five previously reported genotypes, were inoculated onto 27 common bean genotypes having different combinations of CBB resistance QTL and markers. Eight host genotypes were identified that were resistant to all pathogen genotypes. The second objective was to compare direct disease selection (DDS) with marker-assisted selection (MAS) for the development of CBB resistant breeding lines, and the cost-effectiveness of the two selection methods. More CBB-resistant breeding lines were generated with DDS under conditions of high disease pressure in the greenhouse. However, under moderate disease pressure in the field, there were no significant differences between the two selection techniques. Under the parameters of this study, DDS was more cost-effective than MAS. Finally, the relationship between flower and seed color, CBB resistance, a CBB resistance SCAR marker (BC420) and the SOD12490 marker associated with the V pigmentation locus was investigated. In an F2 population and in the F3 progeny test, no recombination was found between colored flowers (purple [P] and lilac [L]), a dark undesirable DRK seed coat color and presence of the BC420 marker. All plants in the F2 and F3 that lacked the BC420 marker had white/lilac-striped (wl) flower color and the desirable DRK seed color. The SOD12490 marker was not linked with CBB resistance. Some plants with wl flowers were resistant but lacked the BC420 marker, indicating unidentified QTL in the CBB-resistant donor germplasm (VAX 3, Wilkinson 2, or I9365-25). Together, this information will facilitate the improvement of CBB resistance in all market classes of common bean.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The common bean (Phaseolus vulgaris L.) is consumed by millions of people worldwide and is a staple source of protein, starch and micronutrients. Common bean production across the world is affected by abiotic and biotic stresses that limit the growth and yield of this important crop. Efforts to breed improved common bean for dissemination to farmers and consumers in East Africa is underway in several breeding programs worldwide. Improvement on agronomic and consumer traits such as disease resistance can be greatly aided by the application of next generation sequencing technologies. With the decreasing cost of DNA sequencing, genomic re-sequencing of diverse common bean accessions facilitates marker- assisted breeding that can be used to speed the creation of new common bean cultivars. Marker-assisted selection (MAS) is an important aspect of modern bean breeding that seeks to utilize genetic markers to select individuals with improved agronomic and consumer traits. For example, breeders in the African Bean Consortium seek to introgress known genetic loci conferring resistance to multiple diseases into bean genetic backgrounds with preferred seed and agronomic characteristics. However, the usefulness of markers is dependent on whether they are polymorphic in the specific parents of the breeding program. Often genetic markers identified in a specific plant population are not useful for marker assisted selection among a different set of bean parents, which necessitates identification of novel markers linked to the genes of interest that are polymorphic among breeding parents. One disease that greatly affects common bean production in humid tropical and sub-tropical growing regions is Angular Leaf Spot (ALS; caused by the foliar fungus Pseudocercospora griseola Sacc.). Marker assisted breeding is being used in multiple different bean breeding programs to improve the resistance of adapted cultivars to ALS. The ALS resistance locus, Phg-2, is an important resistance locus used to improve plant resistance to Angular Leaf Spot in South America and Pan Africa, however in the case of the African Bean Consortium breeding programs in East Africa, certain bean parents used for breeding were monomorphic for the original marker used to perform marker assisted selection of Phg-2. In order to facilitate marker assisted selection of Phg-2 in specific breeding parents used in the Uganda bean improvement program, an alternative, co-dominant, marker linked to the Phg-2 ALS resistance locus was developed (Chapter 1). A new marker, g796, was identified which is polymorphic among the breeding parents; its co-segregation was confirmed in a segregating F2 population derived from the cross between French bean variety Amy and the ALS resistance donor, Mexico 54. This work was conducted in collaboration with Stephen Kimno and Esther Arunga at Embu University, Kenya, as well as other members of the African Bean Consortium bean breeding programs in Tanzania, Uganda, and Ethiopia. The application of DNA sequencing to marker-assisted breeding and crop improvement is rapidly becoming common in the development of improved bean varieties. A nearly complete reference genome and transcriptome for Phaseolus vulgaris was released in 2014 and newly resequenced genomes of diverse bean accessions are being developed for the purpose of marker assisted breeding. In Chapter 2, whole-genome resequencing of 29 bean accessions, including accessions commonly used as breeding parents, was carried out in collaboration with the Ratz lab at the International Center for Tropical Agriculture (CIAT, Colombia). Genetic diversity analysis was performed in order to access the evolutionary relationships between the sequenced bean genomes. Data generated by this work was made available to the larger bean research community and will be used by breeders and geneticists to perform marker-assisted selection and genetic analysis in the future. Angular leaf spot (ALS) occurs throughout Eastern and Southern Africa (as well as other parts of the world) and can cause yield losses up to 80% in environments that favor the disease. ALS is caused by the fungal pathogen, Pseudocercospora griseola, a highly diverse pathogen with many different races that infect diverse types of bean hosts. Growing crop cultivars with genetic resistance to the disease is one of the most effective measures for farmers to reduce crop losses due to ALS. The landrace Mexico 54 is used as a donor for ALS resistance in East Africa and marker-assisted selection of the Phg-2 ALS resistance locus from Mexico 54 is underway in multiple breeding programs in order to increase the resistance of adapted bean germplasm in East Africa and Brazil. Previous allelism tests between different ALS resistance donors suggested additional resistance loci exist in Mexico 54 besides the Phg-2 locus and were named Phg-5 and Phg-6. The genomic locations of the proposed Phg-5 and Phg-6 resistance genes in Mexico 54 have never been investigated, however, the existence of multiple resistance loci in Mexico 54 is likely the cause of its high level of resistance to ALS on multiple continents. In Chapter 3, a biparental mapping population consisting of 167 F8 recombinant inbred lines (RIL) was derived from a cross between Kablanketi, a preferred bean market type in Tanzania, and Mexico 54 in order to map additional quantitative trait loci that confer resistance to ALS in Mexico 54. The identification of novel ALS resistance loci will aid breeders to develop resistant cultivars as well as provide a greater understanding of the genetic diversity that influences resistance to ALS.

Book Synopsis Genomic Designing of Climate-Smart Pulse Crops by : Chittaranjan Kole
Download or read book Genomic Designing of Climate-Smart Pulse Crops written by Chittaranjan Kole and published by Springer. This book was released on 2019-05-28 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the concepts, strategies and techniques for pulse-crop improvement in the era of climate change, highlighting the latest advances in plant molecular mapping and genome sequencing. Genetic mapping of genes and QTLs has broadened the scope of marker-assisted breeding and map-based cloning in almost all major pulse crops. Genetic transformation, particularly using alien genes conferring resistance to herbicide, insects and diseases has facilitated the development of a huge number of genetically modified varieties of the major pulse crops. Since the genome sequencing of rice in 2002, genomes of over 7 pulse crops have been sequenced. This has resulted in the possibility of deciphering the exact nucleotide sequence and chromosomal positions of agroeconomic genes. Most importantly, comparative genomics and genotyping-by-sequencing has opened up a new vista for exploring wild crop relatives for identification of useful donor genes.

Download or read book Dry Beans and Pulses written by Muhammad Siddiq and published by John Wiley & Sons. This book was released on 2012-08-29 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common beans and pulses are diverse food resources of high nutritional value (protein, energy, fiber and vitamins and minerals) with broad social acceptance. These legume crops demonstrate global adaptability, genotypic and phenotypic diversity, and multiple means of preparation and dietary use. Beans and pulses are produced in regions as diverse as Latin America, Africa, Asia, and North America, and on a scale similar to some other crops, such as wheat, corn, rice and soybeans. Numerous factors influence utilization, including bean type and cultivar selection, cropping environment and systems, storage conditions and handling infrastructure, processing and final product preparation. Nutrient content and bio-availability are dramatically influenced by these conditions. In recent years, beans and pulses have been cited for imparting specific positive health potentiating responses, such as hypocholesteremic response, mitigation of diabetes and colonic cancer, and weight control. Enhanced dry bean utilization focused on improved dietary health is an opportunity within both subsistent and developed populations. This book provides a contemporary source of information that brings together current knowledge and practices in the value chain of beans/pulses production, processing, and nutrition. It provides in-depth coverage of a wide variety of pertinent topics including: breeding, postharvest technologies, composition, processing technologies, food safety, quality, nutrition, and significance in human health. An experienced team of over 25 contributors from North America, Asia, and Africa has written 15 chapters, divided into three sections: Overview, production and postharvest technologies of beans and pulses Composition, value-added processing and quality Culinology, nutrition, and significance in human health Contributors come from a field of diverse disciplines, including crop sciences, food science and technology, food biochemistry, food engineering, nutritional sciences, and culinology. Dry Beans and Pulses Production, Processing and Nutrition is an essential resource for scientists, processors and nutritionists, whatever the work setting.

Download or read book Common Bean Improvement in the Twenty-First Century written by S.P. Singh and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common bean (Phaseolus vulgaris L. ) is the most important pulse crop in the world. It is an important source of calories, proteins, dietary fibers, minerals, and vitamins for millions of people in both developing and developed countries worldwide. It complements cereals and other carbohydrate-rich foods in providing near-perfect nutrition to people of all ages. Moreover, a regular intake ofbeans helps lower cholesterol and cancer risks. Despite the fact that per capita consumption of common bean in some developed countries (e. g. , the U. S. A. ) has been increasing over the last several years, in general, the average global per capita consumption is declining because production is unable to keep up with the population growth. Moreover, increasing demand for pesticide-free food products, concern for natural resources conservation, and the need to reduce production costs offer daunting challenges to the twenty-first century policy makers, bean growers, and researchers alike. High yielding, high quality bean cultivars that require less water, fertilizers, pesticides, and manual labor combined with integrated management of abiotic and biotic stresses will have to be developed. Eminent bean researchers were invited to contemplate these issues, prepare a state-of-the-art account on most relevant topics, and offer their insight into research directions into the twenty-first century. Four excellent books have been published covering various aspects ofthe common bean since 1980. These books are: I) Bean Production Problems nd in the Tropics (l SI ed. 1980, 2 ed. 1989), H. F. Schwartz & M. A.
