Cadmium is a toxic unnecessary element for humans and plants which is easily absorbed by plants. Genetic variation in cadmium accumulation provides an opportunity for breeding programs to select genotypes with low cadmium. Due to the high cost of plant tissue analysis to determine the amount of cadmium, use of markers to make efficient selection of low cadmium accumulating genotypes is an effec...
breeding for resistance is one of the main approaches to control diseases. in this approach, there is a necessary for existence a sufficient genetic variability of resistance genes. accordingly, assessing the genetic variability in the available germplasm is needed to manage genetic resources. molecular markers are effective tools to investigate genetic diversity for resistance to pathogens. nb...
The domesticated silkworm, Bombyx mori, is of high commercial importance as a silk producer and is also widely used for implementation of basic and applied research. It is important to understand its genome organization using molecular markers for genetic studies and for breeding purposes. In this study, a genetic linkage map using 204 amplified fragment length polymorphism (AFLP) markers was d...
Extended Abstract Introduction and Objective: Sugar beet is one of the most important agricultural products in the world and most of the sugar consumed in our country is prepared from this plant. Plant breeding programs are based on creating variety and selection of quantitative and qualitative traits. Examining genetic diversity is the first step in breeding programs. Material and Methods: I...
Association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. This study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. This investigation was performed using 77 barley genotypes and AFLP markers. In phenotypic evaluation, reaction of seedlings to powdery mild...
Molecular markers are considered as useful tools for breeding , screening and genetic characterization of genotypes . In crop plants, using of marker assisted selection (MAS) for traits such as product quality and resistance to pests and diseases is being widely adopted by numerous breeding programs worldwide. In current study effects of high molecular glutenin subunit loci Glu1, a lleles 2*,...
objective: dna markers are one of the most important indicators for estimating molecular weight of dna samples, although it used in widespread medical and research laboratories. these markers are very divers and have been prepared in different manners and from different sources of dna. but unfortunately, dna markers haven't been made in our country and all of the markers that we use are made in...
One concern about using transgenic plants is the genetic variation that occurred from theirs tissue culture and regeneration. Molecular markers are an important element for efficient and effective determination of genetic variation. The present work was carried out to assess the genetic uniformity of transgenic cottons (Bt and chitinase lines), using RAPD, ISSR molecular markers and SDS-PAGE an...

in this research work, genetic diversity of 21 wild persian shallot (allium hirtifolium boiss.) accessions from south, southwest, west and center of iran was evaluated using morphological traits as well as aflp markers. results showed that khansar accession had the highest leaf width (5.42 cm), mean leaf number per plant (5.41), bulb diameter (10.84 cm), bulb height (4.95 cm) and mean bulb weig...
