Genomic Prediction of Barley Hybrid Performance
Plant Genome - Tập 9 Số 2 - 2016
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 potential to predict
the hybrid performance...
Genome‐Wide Association Studies of Grain Yield Components in Diverse Sorghum Germplasm
Plant Genome - 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 [Sorghum bicolor
(L.) Moench], a ha...
Genome‐Wide Association Study for Nine Plant Architecture Traits in Sorghum
Plant Genome - 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 used method to investigate the genetic
mechanisms underlying...
Ridge Regression and Other Kernels for Genomic Selection with R Package rrBLUP

A Modified TILLING Method for Wheat Breeding
Plant Genome - Tập 2 Số 1 - 2009
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 M1 plant, storage of M2
seeds, usi...
Status and Prospects of Association Mapping in Plants
Plant Genome - Tập 1 Số 1 - 2008
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. Associatio...
Single Nucleotide Polymorphism Genotyping for Breeding and Genetics Applications in Chickpea and Pigeonpea using the BeadXpress Platform
Plant Genome - 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 effecti...
AGHmatrix: R Package to Construct Relationship Matrices for Autotetraploid and Diploid Species: A Blueberry Example
Plant Genome - 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 information that
accounts for a...
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
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 developed an Axiom Cajanus SNP array with
56K SNPs uniformly...
CaDMR1 Cosegregates with QTL Pc5.1 for Resistance to Phytophthora capsici in Pepper (Capsicum annuum)
Plant Genome - Tập 7 Số 2 - 2014
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
generated in a set of recombinant inbred lines (RIL) derived from the highly
resistant Capsicum ...
