SRAP Molecular Markers Linked to Three Morphological Traits in Egyptian Bread Wheat (Triticum aestivum L.)

Sequence Related Amplified Polymorphism (SRAP) molecular technique was used for assessing the genetic diversity of eight Egyptian bread wheat (Triticum aestivum L.) genotypes. Five SRAP primers combinations were able to expose polymorphism between studied The percentage (P %) ranged from 40 79.90 %. Furthermore, Polymorphic Information Content (PIC) values combination varied 0.11 0.31 with an average 0.19. ME5F-EM2R and ME1F-EM2R primer cleared higher levels 66.67 76.90%, respectively. results Single Marker Analysis (SMA) showed that marker ME1-EM21320bp could be considered probably as candidate linked spike length in tested Moreover, ME1-EM2900bp ME1-EM2575bp markers plant height tillers number /plant traits, Results significant marker-trait associations (P= 0.04), 0.02) tillers/plant 0.03). Me1F-Em6R850bp also height, a specific fragment 850bp tolerant genotype (P1). UPGMA cluster analysis based on separated genotypes into three significantly different clusters. dendrogram morphological traits divided two Mantel test revealed there positive but non-significant correlation similarities phenotypic data (r = 0.36, P> 0.05).
