بررسی تنوع و روابط ژنتیکی بین تعدادی از ارقام برنج با استفاده از صفات زراعی و نشانگرهای مولکولی RAPD

Identification of rice germplasm is necessary for aplication of genetic resources for rice breeding. In this purpose 30 rice genotypes evaluated based on important agronomic traits and RAPD markers. The maximum variation coefficient belonged to unfilled grain (76.6%) and minimum to panicle iength (18.46%). results of Euclidean similarity coefficient and UPGMA algorithm indicated 3 distanced groups. The maximum similarity related between Sang-Joe and Domsia (69%) and the minimum to the Sang-Tarom and Binam genotypes (10.01%). Towelve RAPD primers out of 24 primers indicated suitable polymorphism and its cluster analysis also shown 4 groups that Amol2 with Haraz with maximum similarity (94.2%) and Zire-bandpay with minimum similarity (34.2%).
