ABSTRACT Pi7(t), a dominant blast resistance gene derived from the rice cultivar Moroberekan, confers complete resistance against the fungal pathogen Magnaporthe grisea. Pi7(t) previously was positioned on chromosome 11 by restriction fragment length polymorphism (RFLP) mapping of a recombinant inbred line population. One derivative of this population, recombinant inbred line (RIL)29, was desig...
To exploit the diversity in Arabidopsis thaliana, eight founder accessions were crossed to produce six recombinant inbred line (RIL) subpopulations, together called an Arabidopsis multiparent RIL (AMPRIL) population. Founders were crossed pairwise to produce four F1 hybrids. These F1s were crossed according to a diallel scheme. The resulting offspring was then selfed for three generations. The ...
to enhance germplasms of bread wheat, a gene, encoding the smallest y-type high molecular weight glutenin subunit (hmw gs) gene (12.4t) from the d-genome using synthetic hexaploid approach was introgressed into bread wheat. tetraploid wheat (t. turgidum cv. langdon) was crossed with t. tauschii accession aus24092. immature embryos were rescued and placed onto b5 regeneration media. hybrid f1 pl...
This paper describes two joint linkage-linkage disequilibrium (LD) mapping approaches: parallel mapping (independent linkage and LD analysis) and integrated mapping (datasets analyzed in combination). These approaches were achieved using 2,052 single nucleotide polymorphism (SNP) markers, including 659 SNPs developed from drought-response candidate genes, screened across three recombinant inbre...
To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...
Salt stress impedes plant growth and disrupts normal metabolic processes, resulting in decreased biomass increased leaf senescence. Therefore, the ability of a to maintain when exposed salinity is critical for production salt tolerant crops. To identify genetic basis tolerance an agronomically important grain crop, we used recombinant inbred line (RIL) population derived from interspecific cros...
Quantitative trait loci (QTL) mapping is a powerful tool for investigating the genetic basis of natural variation. QTL can be mapped using a number of different population designs, but recombinant inbred lines (RILs) are among the most effective. Unfortunately, homozygous RIL populations are time consuming to construct, typically requiring at least six generations of selfing starting from a het...
In the construction of recombinant inbred lines (RILs) from two divergent inbred parents certain genotype (or epigenotype) combinations may be functionally "incompatible" when brought together in the genomes of the progeny, thus resulting in sterility or lower fertility. Natural selection against these epistatic combinations during inbreeding can change haplotype frequencies and distort linkage...
High-throughput phenotypic identification is a prerequisite for large-scale and gene mining of important traits. However, existing work has rarely leveraged high-throughput into quantitative trait locus (QTL) acquisition in wheat crops. Clarifying the feasibility effectiveness data obtained from UAV multispectral images traits an urgent problem to be solved wheat. In this paper, 309 lines sprin...
The ND18 strain of Barley stripe mosaic virus (BSMV) infects several lines of Brachypodium distachyon, a recently developed model system for genomics research in cereals. Among the inbred lines tested, Bd3-1 is highly resistant at 20 to 25 °C, whereas Bd21 is susceptible and infection results in an intense mosaic phenotype accompanied by high levels of replicating virus. We generated an F(6:7) ...
