Genetic Diversity of Turkish Cultivated Emmer (Triticum dicoccum Schrank) Revealed by Microsatellite Markers

Abstract

The aim of this study is to evaluate the genetic diversity of twelve populations for cultivated emmer (Triticum dicoccum Schrank ex Schübl) and bread wheat (Triticum aestivum L.) species, which are important wheat gene resources and grown in different villages in Kars province (Turkey), using eleven microsatellite markers. SSR primers produced a total of 41 alleles and the average polymorphism percentage was 86.2%. The average number of alleles obtained from primers was 3.72. Polymorphic Information Content (PIC) values varied between 0.14 and 0.37 with the means of 0.26 value. The primers of Xgwm-46 (0.287), Xgwm-154 (0.304) and Xgwmn-361 (0.325) were identified as the most effective primers in understanding the genetic diversity of emmer genotypes. Local emmer wheat had a little higher allelic richness and gene diversity than cultivated wheat. Due to geographic and climatic variations, genetic differentiation was detected in these wheat populations.
