Download or read book Introducing Sparsity Into Selection Index Methodology with Applications to High throughput Phenotyping and Genomic Prediction written by Marco Antonio Lopez Cruz and published by . This book was released on 2020 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in plant and animal breeding has been largely focused on the development of methods for a more efficient selection by altering the factors that affect genetic progress: selection intensity, selection accuracy, genetic variance, and length of the breeding cycle. Most of the breeding efforts have been primarily towards increasing selection accuracy and reducing the breeding cycle.Genomic selection has been successfully adopted by many public and private breeding organizations. Over years, these institutions have developed and accumulated large volumes of genomic data linked to phenotypes from multiple populations and multiple generations. This data abundance offers the opportunity to revolutionize genetic research. However, these data sets are also increasingly heterogeneous, with many subpopulations and multiple generations represented in the data. This translates into potentially heterogeneous allele frequencies and different LD patterns, thus leading to SNP-effect heterogeneity.Genomic selection methods were developed with reference to homogeneous populations in which SNP-effects are assumed constant across the whole population. These methods are not necessarily optimal for the contemporary available data sets for model training. Therefore, a first focus of this dissertation is on developing novel methods that can leverage the large-scale of modern data sets while coping with the heterogeneity and complexity of this type of data.In recent years, there have also been important advances in high-throughput phenotyping (HTP) technologies that can generate large volumes of data at multiple time-points of a crop. Examples of this include hyper-spectral imaging technologies that can capture the reflectance of electromagnetic power by crops at potentially thousands of wavelengths. The integration of HTP in genetic evaluations represents a great opportunity to further advance plant breeding; however, the high-dimensional nature of HTP data poses important challenges. Therefore, a second focus of this dissertation is on the development of a novel approach to efficiently incorporate HTP data for breeding values prediction.Thus, this dissertation aims to contribute novel methods that can improve the accuracy of genomic prediction by optimizing the use of large, potentially heterogeneous, genomic data sets and by enabling the integration of HTP data. We present a novel statistical approach that combines the standard selection index methodology with variable-selection methods commonly used in machine learning and statistics, and developed software to implement the method. Our approach offers solutions to both genomic selection with potentially highly heterogeneous genomic data sets, and the integration of HTP in genetic evaluations.
Download or read book The Usage of Genomic Selection Strategy in Plant Breeding written by Mohd Shamshad and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Major paradigm shift in plant breeding since the availability of molecular marker technology is that mapping and characterizing the genetic loci that control a trait will lead to improved breeding. Often, one of the rationales for cloning of QTL is to develop the "perfect marker" for MAS, perhaps based on a functional polymorphism. In contrast, an advantage of genomic selection is precisely its black box approach to exploiting genotyping technology to expedite genetic progress. This is an advantage in our view because it does not rely on a "breeding by design" engineering approach to cultivar development requiring knowledge of biological function before the creation of phenotypes. Breeders can therefore use genomic selection without the large upfront cost of obtaining that knowledge. In addition, genomic selection can maintain the creative nature of phenotypic selection which couple's random mutation and recombination to sometimes arrive at solutions outside the engineer's scope. Currently, the lion's share of research on genomic selection has been performed in livestock breeding, where effective population size, extent of LD, breeding objectives, experimental design, and other characteristics of populations and breeding programs are quite different from those of crop species. Nevertheless, a great number of findings within this literature are very illuminating for genomic selection in crops and should be studied and built upon by crop geneticists and breeders. The application of powerful, relatively new statistical methods to the problem of high dimensional marker data for genomic selection has been nearly as important to the development of genomic selection as the creation of high-density marker platforms and greater computing power. The methods can be classified by what type of genetic architecture they try to capture.

Download or read book Genomic Prediction in Practice written by Kristina Louise Estelle Weber and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The inclusion of genomic information into animal breeding predictions can provide more accurate breeding values for selection candidates at a younger age and facilitate selection for expensive or difficult to measure traits. Genomic prediction involves using large training populations with phenotypes and high density genotypes to estimate genetic effects throughout the genome. Implementing genomic selection in the beef industry presents challenges, both in development and application. To investigate the potential for accurate across breed genomic prediction, Bayesian algorithms were used to derive prediction equations for 52,156 SNP loci using approximately 2,000 mixed purebred bulls or 3,400 crossbred cattle with deregressed EPD or phenotypes for growth and carcass traits. MBV accounted for up to 18% of genetic variation in a pooled, multi-breed analysis and up to 42% in single breed subpopulations, depending on trait, and were more accurate in Angus and Hereford breeds as these were highly represented in both multi-breed training populations. These multi-breed derived genomic predictions were compared with Angus-derived genomic predictions in a commercial cattle population consisting of Angus bulls bred on four commercial cow-calf ranches in Northern California and producing nearly 6,000 phenotyped progeny. Compared with Angus-derived genomic predictions, multi-breed genomic predictions had lower accuracy (

Book excerpt: With the combination of global climate changes and the rapid increase of the human population, genomic selection is an emerging tool that can be used to improve our crops and sustainably maintain global agricultural needs of the present and future. In the previous century, agricultural breeding was determined by the phenotypes of available parent lines - phenotypic selection - and used to assess which crops would yield the most economically viable harvests. With new techniques, such as genomic selection, crop yields have been shown to increase while simultaneously reducing the amount of breeding cycles needed to achieve a desired phenotype during times of increasingly challenging climates [1].

Download or read book Integrating High throughput Phenotyping Genomic Selection and Spatial Analysis for Plant Breeding and Management written by Margaret Rose Krause and published by . This book was released on 2019 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in high-throughput phenotyping, genomics, and precision agriculture have provided plant breeders and farmers with a wealth of information on the growth and development of crop plants. Methods for effectively leveraging these data resources are needed in order to drive genetic gain in breeding programs and to increase efficiency in farming systems. Three novel approaches for the development and management of high yielding, adapted crop varieties are presented. First, aerial hyperspectral reflectance phenotypes of bread wheat (Triticum aestivum L.) were used to develop relationship matrices for the prediction of grain yield within and across environments with genomic selection. Multi-kernel models combining marker/pedigree information with hyperspectral reflectance phenotypes gave the highest accuracies overall; however, improvements in accuracy over single-kernel marker- and pedigree-based models were reduced when correcting for days to heading. Second, aerial phenotypes collected on small, unreplicated plots representing the seed limited stage of wheat breeding programs were evaluated for their potential use as selection criteria for improving grain yield. The aerial phenotypes were shown to be heritable and positively correlated with grain yield measurements evaluated in replicated yield trials. Results also suggest that selection on aerial phenotypes at the seed-limited stage would cause a directional response in phenology due to confounding of those traits. Lastly, on-farm trials were conducted in collaboration with the New York Corn and Soybean Growers Association to identify optimal planting rates for corn (Zea mays L.) and soybean (Glycine max L.) given the underlying spatial variability of the soil and topographical characteristics of the fields. A random forest regression-based approach was created to develop variable rate planting designs for maximizing yields.
Download or read book Advances and Applications of Cost Effective High Throughput Genotyping Technologies for Sustainable Agriculture written by Nisha Singh and published by Frontiers Media SA. This book was released on 2023-12-28 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in next-generation sequencing-driven mass production of genomic data and various other integrated techniques have considerably broadened and deepened our understanding of living organisms' molecular systems. Because complex quantitative traits are difficult to select due to low heritability, conventional plant breeding relies on phenotypic selection and breeder experience, it takes longer to develop a new, improved variety. For association studies to identify DNA markers linked to these complex traits, genotyping chip arrays allow genotyping of thousands of markers in a short amount of time. Plant breeding consistency and predictability have improved thanks to advances in genomics. NGS technologies bring new tools and concepts that can enhance the precision and efficiency of plant breeding such as cost-effective, high throughput genotyping technologies for sustainable agriculture. These genotyping technologies will be lowering the time and cost of developing high-quality food crops that are stress-resistant while still having a high nutritional value. This Research Topic focuses on recent advancements in NGS-related technologies, mainly the development of cost-effective high-throughput genotyping platforms with a wide range of bioinformatics tools, and possible translational multi-omics applications in crop breeding programs for sustainable agriculture.
