Molecular mapping of segregation distortion loci in Aegilops tauschii.
Distorted segregation ratios of genetic markers are often observed in progeny of inter- and intraspecific hybrids and may result from competition among gametes or from abortion of the gamete or zygote. In this study, 194 markers mapped in an Aegilops tauschii F2 population were surveyed for distorted segregation ratios. Region(s) with skewed segregation ratios were detected on chromosomes 1D, 3...
متن کاملGenetic Mapping of an Aegilops tauschii–derived Hessian Fly Resistance Gene in Common Wheat
Hessian fl y [Mayetiola destructor (Say)] is a major threat to wheat (Triticum aestivum L.) production in the eastern United States. Cultivar releases containing major Hessian fl y resistance genes have proven effective in minimizing losses caused by this pest. Nevertheless, the ephemeral nature of major gene resistance necessitates the identifi cation of novel sources of resistance. Hessian fl...
متن کاملQTL mapping of heading date and plant height in Barley cross “Azumamugi”דKanto Nakate Gold
To identify quantitative trait loci (QTLs) controlling heading date and plant height, ninety nine F13 recombinant inbred lines (RILs) derived from barley cultivars Azumamugi × Kanto Nakate Gold cross were evaluated. The field trails were conducted at randomized complete block design with two and three replications in 2004 and 2005, respectively. Significant differences and transgrassive segrega...
متن کاملImportance of QTL Mapping for Heading Date in Rice
Heading date in rice is one of the most important indices in rice breeding being governed by multiple genes known as quantitative trait loci (QTLs). This character along with grain yield determines the commercial potential of any rice cultivar. In the last three decades the development of DNA markers have led to the precise analysis of QTLs. Various mapping populations are being used to explore...
متن کاملCharacterization of the CCT family and analysis of gene expression in Aegilops tauschii
Flowering is crucial for reproductive success in flowering plant. The CCT domain-containing genes widely participate in the regulation of flowering process in various plant species. So far, the CCT family in common wheat is largely unknown. Here, we characterized the structure, organization, molecular evolution and expression of the CCT genes in Aegilops tauschii, which is the D genome donor of...
