In this study, genetic diversity of two different populations of Hamra goat breed of Morocco was investigated in 60 different samples (including 30 from Beni Arouss and 30 from Rommani) using fifteen microsatellite markers. A total of 145 alleles were detected with average number per locus of 8.67 and 8.07 in Beni Arouss and Rommani goats, respectively. The Shannon’s information index ranged fr...

Annual medics are used for hey production, soil protection, biological fixation of N2 and green manure. In the present study, the inter and intra specific genetic diversity and relatedness of 4 diploid and two tetraploid (M. rugosa and M. scutellata) annual medics were evaluated using microsatellite markers. PCR analysis was performed on genomic DNA from individual plant and PCR products were d...

The genetic diversity of a large number of pistachio genotypes grown in Iran is not exactly known. Most of the studies on genetic diversity of Iranian pistachio varieties are based on morphological characteristics or isozyme markers. In the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by Amplified Fragment Length Polymorphism (...

In order to select the best parents for crossings, plant breeders seek varieties or genotypes with highest genetic dissimilarities. This can be achieved by measuring the similarities among genotypes, using multivariate analysis methods such as cluster analysis. This study aimed to group 50 aerobic and lowland rice genotypes based on biochemical characteristics including Iron, Zinc, Manganese an...

expressed sequence tags simple sequence repeats (est-ssrs) are important sources for investigation ofgenetic diversity and molecular marker development. similar to genomic ssrs, the est-ssrs are usefulmarkers for many applications in genetics and plant breeding such as genetic diversity analysis, molecularmapping and cross-transferability across related species and genera. in spite of low polym...

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...

       Aeluropus littoralis is one the most successful monocot grasses in terms of high salinity tolerance, that contains forage quality and has valuable physiological features. The goal of this study is to introduce and provide quick access to DNA-based molecular markers for valuable halophyte, Aeluropus littoralis to assessment of genetic diversity.  For this, a total number of 110 EST-SSR ma...

The validity test of the linked markers to identified QTLs is as a necessary step before performing marker assisted selection. In the present study were conducted validity test of 21 microsatellite markers associated to drought tolerance using 121 soybean varieties and advanced lines and planting in two condition normal and under drought stress at two regions Rasht and Gonbad-Kavous. In investi...

Twenty-two G. glabra populations were used to study the genetic diversity of ISSR molecular markers. 12 primers were used to amplification of genomic DNA fragments of G. glabra populations. High genetic diversity based on ISSR markers was observed among individuals. A total of 130 bands were formed and 105 bands were polymorphic. The mean polymorphism percentage among studied populations was 80...
