Available in PDF, EPUB and Kindle. Book excerpt: Bambara groundnut is an indigenous African legume grown mainly in sub-Saharan Africa; it is an important source of protein to the rural majority. There are no established varieties and subsistence farmers grow locally adapted landraces which are generally low yielding. Bambara groundnut is a predominantly self-pollinating crop and is expected to exist as non-identical inbred lines, although the previous lack of co-dominant markers has prevented a formal assessment of heterozygosity within bambara groundnut genotypes. A total set of 75 microsatellites that were characterised in this study were used to investigate the genetic diversity of a set of 24 bambara groundnut landraces, to provide an evaluation of the markers for polymorphism and provide a link with DArT marker data that were previously analysed. Sixty eight microsatellites were identified that were found to be consistent and reproducible, from which a set of markers were selected and used for genetic variability studies of bambara groundnut, to compare the use of molecular markers with morphological markers, and to investigate using SSR markers in pure line selection. The genetic diversity of bambara groundnut was assessed based on morphological characters for two seasons; in a glasshouse experiment at the University of Nottingham, Sutton Bonington Campus, UK and in a field experiment that was conducted at the Botswana College of Agriculture (Notwane farm), Gaborone in a randomised block design with three replicates. The landraces were characterised for 24 quantitative and 13 qualitative characters. The results indicated considerable variation for quantitative characters, while significant morphological differences were also recorded for most characters. Multivariate data analysis was conducted using principal component analysis, cluster analysis and heritability estimates were developed. The low cost, simplicity and agricultural relevance of morphological characterisation makes it an important tool in germplasm genetic variation studies. Thirty four lines from field experiments were investigated for genetic diversity based on 20 microsatellites. The expected heterozygosity (He) had an average of 1 in agreement with the fact that bambara groundnut is predominantly self-pollinating. Both cluster analysis and principle component analysis (PCoA) grouped landraces based mainly on their areas of origin. A thorough molecular analysis of genetic and morphological variation in bambara groundnut was conducted to investigate the relationship between the two assessment techniques. This comparison will assist in breeders making informed decisions as to which approach is best to use in germplasm characterisation and plant breeding and how best to apply such knowledge in practical situations. DNA markers could then aid with the selection of germplasm for breeding, quality control within breeding programmes and, potentially, direct selection via Marker Assisted Selection (MAS). Euclidean distance estimates for morphological data and (Nei's 1972) genetic distance estimates for SSR data were strongly correlated (r = 0.7; P

This book was released on 2024-01-18 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orphan crops play an important role in food and nutrition security especially in growing economies where small-holder farmers produce the majority of food. Despite their importance in global agriculture and their often remarkable nutrient content and adaptation to challenging environmental conditions, orphan crops have received limited attention by the scientific community and industry. However, the diversity of neglected plant species provides a large genetic resource that could significantly contribute to broadening the biodiversity of trait-desired crops for novel value chains, sustainable development and food security. The uptake of new plant breeding techniques, notably genome editing, as well as ‘omic’ tools, are now accelerating translation of basic research and facilitating the exploration of orphan crops. These advancements also give rise to public and politic engagement discussions to maximize socio-economic impact. Given that the greatest need for food and nutritional security is in growing economies, issues of food sovereignty and sustainability of their food systems become front-and-centre. There is now an exceptional opportunity to tackle some of the major current challenges in agriculture, including climate change, sustainable cropping systems, food quality, and nutritional security through broadening research in wild relatives of crops and on orphan species. This Research Topic seeks to showcase research on neglected plants using advanced molecular technologies (e.g. genome sequencing, 'omics', etc) and new plant breeding approaches, methods, and tools. This Research Topic will also discuss the challenges and opportunities arising when modern breeding techniques are applied for translational research.

This book was released on 2001 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes an approach to assess locations and areal expenses that have potential for the production of bambara groundnut (Vigna subterranea L. Verdc) across the world. The methodology was applied both to regions such as Africa, where the crop is widely cultivated but where experimental evidence is limited, and to new regions that have not previously been associated with bambara groundnut but where environmental factors are conductive for productive growth. A weather generator and a crop simulation model of bambara groundnut (BAMnut) were incorporated into a Geographical Information System (GIS) to predict, for the first time, bambara groundnut production for the world. BAMnut is a process-based model that uses physiological principles to describe the capture and use of environmental resources principally solar radiation and soil moisture. This mechanistic approach allows crop growth and yield to be predicted for regions beyond those used in the development of the model or regions where bambara groundnut is currently cultivated. The preliminary identification of potentially suitable areas for production, based on the agro-ecological requirements of the crop, serve as a useful prelude to detailed field investigations on bambara groundnut to identify appropriate management practices and may provide a basis for a similar assessment on many other underutilized crops.--Publisher's description.

This book was released on 2013 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field experiment to study the effect of plant population density on the growth and yield of five bambara groundnut landraces and to determine the nutritional quality of the seeds was conducted at Kwame Nkrumah University of Science and Technology, Kumasi; at the Department of Crop and Soil Sciences in 2008. The experimental design was a split plot with bambara groundnut landraces; as the main plot factor and the population densities (5,6.7 and 10 plants m-2) as the subplot factor. Results indicated that increasing plant population density resulted in higher pod yield. The highest density of 10 plants m-2 produced significantly the greatest pod and grain yield. The spacing of 50 cm x 20 is recommended for cultivation of bambara groundnut. Seed analysis showed that the landraces contain 26.88-33.75% protein; 54.89-63.67% carbohydrate; 2.45-4.29% fat; from 1.59-3.13% fibre and 2.45-4.28% ash. The results indicate that the landraces contains protein, carbohydrate, fat and fibre in levels that provide balanced nutrition. Cultivation and use of these landraces therefore should be encouraged because the legume has great potential to contribute to food security in Ghana.

Using Novel High-throughput Technologies written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bambara groundnut is a drought-tolerant African legume. In order to estimate biodiversity, a DArT genotyping array was developed from which 296 unique markers were obtained. It was shown that the cultivated form was characterised by a generally narrow genetic basis and further genetic bottlenecks occurred with the dispersal of germplasm. Through 454 pyrosequencing of eight cDNA populations from contrasting genotypes and different treatments and a cDNA microarray constructed from selected transcripts, a complex network of gene regulation in leaves under water-deficit was described. In addition, two potentially novel candidate genes for drought-tolerance were identified. The approaches presented in this thesis could serve as an example to produce significant population genetic and transcriptomic data for other under-researched crops in a time- and cost-efficient way.

Download or read book Bambara Groundnut,The Crop for New Millennium written by Nariman Ahmad and published by LAP Lambert Academic Publishing. This book was released on 2012-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bambara groundnut (Vigna subterranean L. Verdc.) as one of the legume crops belongs to the Phaseoloid-Millettioid clade, which diverged some 45-50 million years ago from the Hologalegina clade. Due to the shortage growing period of Bambara groundnut it ranks the third most important food legume crop in semi-arid Africa in terms of production and consumption. It is highly drought tolerant and resists pest and disease. Bambara groundnut is a rich source of protein, contributing to alleviate nutritional problems in areas where staple foods are predominantly carbohydrate sources. Despite these potential of bambara groundnut it is inadequately characterized and neglected by research community. Employing new biotechnological tools such as DNA markers for mapping and identifying genes for desirable traits can accelerate the improvement of this crop genetically. This book covers the recent progress on genome research in bambara groundnut, including genetic map and QTL analysis using microsatellite and Diversity array technique markers. This will help breeders to effectively pyramid desirable genes into the cultivars in a much shorter time than would possible by conventional breeding.
