چکیده مقاله:

The importance of grain cultivation especially wheat is obvious in terms of providing human and animal food and its impact on the economy of human societies. The reduction of genetic diversity in cultivars prevents increasing yields in line with rising demand and consumption. Therefore, it is necessary to improve the compatibility of them and increase their genetic extent. In the current, the genetic diversity of Iranian wheat genotypes was investigated at the DNA level using RAPD and ISSR markers. 17 RAPD primers and 16 ISSR primers generated 86 (86/99= %86.86) and 56 (56/64= %57.5) polymorphic bands respectively. The cluster analysis based on UPGMA and dendrogram plotted using NTSYSpc 2.02 software revealed three main clusters. The highest genetic distance was between CD-89-2 and CD-89-7 genotypes and the minimum genetic distance was between CD-89-2 and CD-89-3 genotypes. Based on Nei's genetic distance matrix, the mean number of effective bands, the Shannon index, and polymorphism content were 1.381, 0.332, and % 87.12, respectively. Our results showed that RAPD and ISSR analysis are suitable methods to study genetic diversity and relationships among T. aestivum genotypes.

Study of Genetic Diversity in Wheat (triticum Aestivum L.) Using Random Amplified Polymorphic Dna (rapd) Markers

Twelve wheat genotypes developed through hybridization programme were screened for genetic diversity through RAPD marker. A total of 102 loci were amplified with 14 primers out of which 91 (89.2%) were polymorphic and only 11(10.8%) were monomorphic. Fragments size ranged from 142bp-5.3kb and fragments produced by various primers ranged from 1-11 with an average of 7.1 fragments per primer. The...

Genetic Diversity and Linkage Disequilibrium in Chinese Bread Wheat (Triticum aestivum L.) Revealed by SSR Markers

Two hundred and fifty bread wheat lines, mainly Chinese mini core accessions, were assayed for polymorphism and linkage disequilibrium (LD) based on 512 whole-genome microsatellite loci representing a mean marker density of 5.1 cM. A total of 6,724 alleles ranging from 1 to 49 per locus were identified in all collections. The mean PIC value was 0.650, ranging from 0 to 0.965. Population structu...
