Development and Application of High‐Density Axiom Cajanus SNP Array with 56K SNPs to Understand the Genome Architecture of Released Cultivars and Founder Genotypes
Plant Genome - Tập 11 Số 3 - 2018
Rachit K. Saxena, Abhishek Rathore, Abhishek Bohra, Pooja Yadav, Roma Rani Das, Aamir W. Khan, Vikas Kumar Singh, Annapurna Chitikineni, I. P. Singh, C.V. Sameer Kumar, K. B. Saxena, Rajeev K. Varshney
As one of the major outputs of next‐generation sequencing (NGS), a large number of genome‐wide single‐nucleotide polymorphisms (SNPs) have been developed in pigeonpea [Cajanus cajan (L.) Huth.]. However, SNPs require a genotyping platform or assay to be used in different evolutionary studies or in crop improvement programs. Therefore, we d...... hiện toàn bộ
A Modified TILLING Method for Wheat Breeding
Plant Genome - Tập 2 Số 1 - 2009
Chongmei Dong, Jessica Dalton‐Morgan, Kate Vincent, P. J. Sharp
The large genome and polyploidy of wheat (Triticum aestivum L.) makes it difficult to identify desirable genetic changes based on phenotypic screening due to gene redundancy. Forward genetics is, therefore, more difficult in wheat than in diploid plants. A modified TILLING (Targeting Induced Local Lesions IN Genomes) method including the harvest of five heads per...... hiện toàn bộ
Single Nucleotide Polymorphism Genotyping for Breeding and Genetics Applications in Chickpea and Pigeonpea using the BeadXpress Platform
Plant Genome - Tập 6 Số 2 - 2013
Manish Roorkiwal, S. L. Sawargaonkar, Annapurna Chitikineni, Mahendar Thudi, Rachit K. Saxena, Hari D. Upadhyaya, M. Isabel Vales, Oscar Riera‐Lizarazu, Rajeev K. Varshney
Single nucleotide polymorphisms (SNPs) are ideal molecular markers due to their higher abundance. Although several types of genotyping platforms for assaying large number of SNPs are available, in cases such as marker‐assisted selection, where few markers are required for genotyping a set of potential lines, high‐throughput SNP genotyping platforms (e.g., iScan or Infinium) may not be cost...... hiện toàn bộ
Genomic Prediction of Barley Hybrid Performance
Plant Genome - Tập 9 Số 2 - 2016
Norman Philipp, Guozheng Liu, Yusheng Zhao, Sang He, Monika Spiller, Gunther Stiewe, Klaus Pillen, Jochen C. Reif, Li Zuo
Hybrid breeding in barley (Hordeum vulgare L.) offers great opportunities to accelerate the rate of genetic improvement and to boost yield stability. A crucial requirement consists of the efficient selection of superior hybrid combinations. We used comprehensive phenotypic and genomic data from a commercial breeding program with the goal of examining the potentia...... hiện toàn bộ
Genome‐Wide Association Studies of Grain Yield Components in Diverse Sorghum Germplasm
Plant Genome - Tập 9 Số 2 - 2016
Richard Boyles, Elizabeth Cooper, Matthew T. Myers, Zachary Brenton, B. Rauh, Geoffrey P. Morris, Stephen Kresovich
Grain yield and its primary determinants, grain number and weight, are important traits in cereal crops that have been well studied; however, the genetic basis of and interactions between these traits remain poorly understood. Characterization of grain yield per primary panicle (YPP), grain number per primary panicle (GNP), and 1000‐grain weight (TGW) in sorghum [... hiện toàn bộ
Genome‐Wide Association Study for Nine Plant Architecture Traits in Sorghum
Plant Genome - Tập 9 Số 2 - 2016
Jing Hua Zhao, Maria B. Mantilla Perez, Jieyun Hu, Maria G. Salas Fernandez
Sorghum [Sorghum bicolor (L) Moench], an important grain and forage crop, is receiving significant attention as a lignocellulosic feedstock because of its water‐use efficiency and high biomass yield potential. Because of the advancement of genotyping and sequencing technologies, genome‐wide association study (GWAS) has become a routinely u...... hiện toàn bộ
Ridge Regression and Other Kernels for Genomic Selection with R Package rrBLUP
Plant Genome - Tập 4 Số 3 - Trang 250-255 - 2011
Jeffrey B. Endelman
Status and Prospects of Association Mapping in Plants
Plant Genome - Tập 1 Số 1 - 2008
Chengsong Zhu, Michael A. Gore, Edward S. Buckler, Jianming Yu
There is tremendous interest in using association mapping to identify genes responsible for quantitative variation of complex traits with agricultural and evolutionary importance. Recent advances in genomic technology, impetus to exploit natural diversity, and development of robust statistical analysis methods make association mapping appealing and affordable to plant research programs. As...... hiện toàn bộ
AGHmatrix: R Package to Construct Relationship Matrices for Autotetraploid and Diploid Species: A Blueberry Example
Plant Genome - Tập 9 Số 3 - 2016
Rodrigo R. Amadeu, Catherine Cellon, James W. Olmstead, Antônio Augusto Franco Garcia, Márcio F. R. Resende, Patricio Muñoz
Progress in the rate of improvement in autopolyploid species has been limited compared with diploids, mainly because software and methods to apply advanced prediction and selection methodologies in autopolyploids are lacking. The objectives of this research were to (i) develop an R package for autopolyploids to construct the relationship matrix derived from pedigree...... hiện toàn bộ
CaDMR1 Cosegregates with QTL Pc5.1 for Resistance to Phytophthora capsici in Pepper (Capsicum annuum)
Plant Genome - Tập 7 Số 2 - 2014
William Z. Rehrig, Hamid Ashrafi, Theresa Hill, James P. Prince, Allen Van Deynze
A major problem for the pepper (Capsicum annuum) industry is the root rot disease caused by Phytophthora capsici (Pc), to which all commercial varieties suffer yield losses despite good management practices and available landraces with high levels of resistance. A high‐density map with 3887 markers was generat...... hiện toàn bộ
