بررسی تنوع ژنتیکی و طبقه‏بندی ارقام برنج با استفاده از نشانگرهای ریزماهواره پیوسته با مکان‏های ژنی کنترل‏کننده مقدار روی

The study was designed to characterize the genetic diversity within a subset of 50 rice varieties using 15 microsatellite markers linked to the QTLs controlling zinc grain content. The grain Zinc content were measured using atomic absorption with two replications and Neemat and Dadras cultivars with the amount of 10.94 and 36.92 mg.Kg-1 had the lowest and highest grain Zinc content, respectively. According to the analysis of molecular, RM257 was showed highest number of allele and gene diversity (0.8). grouping phenotypic was performed by Complete Linkage method and the squared Euclidean distance, molecular clustering was conducted using Neighbor Net method and coefficient of P Distance. Refer to similarity between molecular and phenotypic clustering for zinc, it is concluded that loci studied in this research are effective in controlling zinc in Iranian rice cultivars. Furthermore the Dadras cultivar can be advised as appropriate a cultivar in zinc grain breeding programs.
