potato virus y (pvy) is one of the most important pathogenic agents that reduce the yield and quality of tobacco (nicotiana tabacum l.). dna-based molecular markers are valuable tools for identifying germplasm in gene banks, assessing kinship ties, and doing marker-assisted selection (mas) for resistance to pests, diseases, and some crop traits of interest. this work presents the results of ass...

Wheat fulfills 20% of global caloric requirement. World needs 60% more wheat for 9 billion population by 2050 but climate change with increasing temperature is projected to affect wheat productivity adversely. Trait improvement and management of wheat germplasm requires genomic resource. Simple Sequence Repeats (SSRs) being highly polymorphic and ubiquitously distributed in the genome, can be a...

The objective of the present study was to make use of efficient molecular marker systems to reveal genetic relationships in traditional and evolved Basmati (EB) and semidwarf non-Basmati (NB) rice varieties. A subset of three rice groups was analyzed by using 19 simple sequence repeat (SSR) loci and 12 inter-SSR-PCR primers. A total of 70 SSR alleles and 481 inter-SSR-PCR markers were revealed ...

Flax (Linum usitatissimum L.) is a major fiber and oil yielding crop grown in northeastern China. Identification of flax molecular markers is a key step toward improving flax yield and quality via marker-assisted breeding. Simple sequence repeat (SSR) markers, which are based on genomic structural variation, are considered the most valuable type of genetic marker for this purpose. In this study...

Maize landraces represent potential sources of favorable traits for current and future breeding programs.. A comparative characterization of twenty-one flint maize landraces from Maize Research Institute "Zemun Polje“ gene bank was achieved by using morphological traits and SSR markers. Applied marker systems revealed high level of genetic heterogenity beetween landraces. Cluster analysis of th...

the applicability of rapds, aflps, and ssrs to examine genetic relationships in 36 populations of triticum boeoticum from west of iran was investigated. a total of 224 (135 polymorphic), 979 (429 polymorphic) and 246 (145 polymorphic) bands/alleles were detected using 14 rapd primers, 17 aflp primer combinations and 17 well distributed, mapped ssr markers, respectively. the polymorphic informat...

Root and stem rot is one of the major diseases of soybean. It is caused by the oomycete pathogen Phytophthora sojae. A series of resistance genes (Rps) have been providing soybean with reasonable protection against this pathogen. Among these genes, Rps8, which confers resistance to most P. sojae isolates, recently has been mapped. However, the most closely linked molecular marker was mapped at ...

Wild soybean, the progenitor of cultivated soybean, is an important gene pool for ongoing soybean breeding efforts. To identify yield-enhancing quantitative trait locus (QTL) or gene from wild soybean, 113 wild soybeans accessions were phenotyped for five yield-related traits and genotyped with 85 simple sequence repeat (SSR) markers to conduct association mapping. A total of 892 alleles were d...

Microsatellite or simple sequence repeat (SSR) markers have been successfully used for genomic mapping, DNA fingerprinting, and marker-assisted selection in many plant species. Here we report the first successful assignment of 15 SSR markers to the Phaseolus vulgaris molecular linkage map. A total of 37 SSR primer pairs were developed and tested for amplification and product-length polymorphism...

To identify cultivars quickly and accurately, DNA fingerprinting of 10 broccoli varieties was performed by using simple sequence repeat (SSR) marker technology. Highly informative polymorphic SSR markers were screened rapeseed. Out the 93 pairs, 21 pairs selected found to have good polymorphism. Each pair generated 1 bands with an average 4.29. The polymorphism information content (PIC) 0.41 a ...
