Genetic mapping of agronomic traits from the interspecific cross of Oryza sativa (L.) and Oryza glaberrima (Steud.)
… explored. A molecular linkage map comprising 100 SSR markers that spanned the rice genome at intervals of 10.5 cM on the average was constructed based on 312 doubled haploid lines derived from the cross interspecific Oryza sativa x O. glaberrima. The mapping population was evaluated in replicated …

Identificazione di un QTL principale per resistenza a ruggine bruna sul cromosoma 7B di frumento duro
… genotypes at 15 simple sequence repeat (SSR) loci, in order to determine their specialization with regard to the host species. The characterization of the leaf rust isolates was conducted at the Cereal Disease Laboratory of the University of Minnesota (St. Paul, USA) (Chapter 2). A …

Assessment of genetic variations within and between populations of Marama Bean (Tylosema Esculentum (Burchell) Schreiber) based on Microsatellites (SSRS) and Intergenic spacer length variation markers in the Namibian germplasm
… the two mostly consumed legumes. In this study SSR markers were used to assess genetic diversity in natural populations of marama in the Namibian germplasm. Additionally, in the present study, the intergenic spacers (IGS) region of the large ribosomal DNA gene was amplified to assess length …

Simple sequence repeat analysis and qualitative pathway analysis of Rathayibacter toxicus
… genetic and genomic studies including MLST, ISSR, and WGS support genetic population groupings and identified a newly emerged population (RT-I) in South Australia. Unique attributes of RT-I preclude determination of its geographic or phylogenetic origin. Simple Sequence Repeats (SSRs) are …

Validation of Loci Conferring Adult Plant Resistance to Powdery Mildew in Wheat Cultivar Massey and Identification of Diagnostic Molecular Markers
… difficult to identity simple sequence repeat (SSR) markers that are tightly linked to the QTL for APR in Massey. Such markers give breeders an advantage by allowing them to quickly identify and select for traits that would be difficult to distinguish in the field among breeding progeny from …

Mapping Quantitative Trait Loci for Soybean Quality Traits from Two Different Sources
… this population. A map was constructed using 141 SSR markers and 15 molecular linkage groups (MLGs) were identified. After analyzing trait and marker data in QTL Cartographer, potential QTL were found on MLGs: B1, C2, D1b, F, M and N. Sucrose and stachyose QTL were identified on B1, C2, M and N. …
