     In Present research, 196 F2:4 families from the cross between two Iranian local and improved rice varieties, Sepidrood and Gharib, were used to identify QTLs controlling cooking and milling quality traits. The polymorphism between parents was evaluated by 550 SSR markers and 10 primer combinations of the AFLP markers and linkage map was constructed by 216 polymorphic markers (105 SSRs and ...

in this research, allele frequency and polymorphism of 27 microsatellite markers linked to gene loci controlling grain quality were determined between 47 rice varieties from four different groups including 21 iranian local, 16 improved, 7 irri and 3 upland rice varieties. average number of polymorphic information content (pic) and shannon’s diversity index were 0.54 and 1.14, respectively. maxi...

Broadly applicable polymorphic genetic markers are essential tools for population genetics, and different types of markers have been developed for this purpose. Microsatellites have been employed as particularly polymorphic markers for over 20 years. However, PCR primers for microsatellite loci are often not useful outside the species for which they were designed. This implies that a new set of...

The investigation of microsatellite markers has recently superseded that of isoenzymes for many population-biology applications. Microsatellites have the advantages of being dominant, neutral, highly polymorphic and easily scored by high-throughput methods. However, it is necessary to develop a new panel of markers for each group of organisms of interest. Previously, only about 5% of the marker...

Powdery mildew (Blumeria graminis f. Sp. Hordei) is one of the most destructive foliar diseases in barley that cause yield reduction worldwide.  DNA molecular markers can be used to study the genetic diversity and better understanding of genetic predisposition to disease resistance to powdery mildew in barley at early growth stage.  Selection of resistance and tolerance need to identify molecul...

a study was conducted to identify ssr markers linked to leaf rust resistance genes lr24 and lr28 and to be used for marker-assisted selection (mas) to transfer both genes to a widely cultivated wheat variety mp 3299 under rainfed condition. f2 individuals of the cross mp 3299×nil pbw 343 were used for generating genotypic data employing closely linked scar markers s73719 and s421570 to lr24 and...

this study was performed for assessment of correlation of 11 morphological traits with rapd molecular markers in 15 cultivars of date palm collected from the south and south west of iran as population analysis by stepwise regression method. the results of simple and multiple regressions showed that in sum 84 rapd markers had significant association with at least one of the traits. the coefficie...

A computational system for the prediction of polymorphic loci directly and efficiently from human genomic sequence was developed and verified. A suite of programs, collectively called POMPOUS (polymorphic marker prediction of ubiquitous simple sequences) detects tandem repeats ranging from dinucleotides up to 250 mers, scores them according to predicted level of polymorphism, and designs approp...

Genus Allium L. contains very taxonomically complex sections, especially the subgenus Melanocrommyum. The systematic position of the species in each section has been revised many times over time. In the present study, the relationship between 32 ecotypes belonging to 10 different species of Allium was investigated using ISSR markers. The nine primers used produced 166 polymorphic bands (average...
