Status and Prospects of Association Mapping in Plants 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 Tập 9 Số 3 - 2016

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 A Modified TILLING Method for Wheat Breeding 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 Genome‐Wide Association Studies of Grain Yield Components in Diverse Sorghum Germplasm Tập 9 Số 2 - 2016

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 Tập 9 Số 2 - 2016

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 Single Nucleotide Polymorphism Genotyping for Breeding and Genetics Applications in Chickpea and Pigeonpea using the BeadXpress Platform Tập 6 Số 2 - 2013

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 Development and Application of High‐Density Axiom Cajanus SNP Array with 56K SNPs to Understand the Genome Architecture of Released Cultivars and Founder Genotypes Tập 11 Số 3 - 2018

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 Genomic Prediction of Barley Hybrid Performance 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
