Genetic Diversity of Genotypes of Durum Wheat (Triticum Turgidum L.) Genotypes Based on Cluster and Principal Component Analyses

Genetic  diversity  is  the  basis  of  the  natural  evolution  of  plant  breeding  and  biological  system  are  important  components  of  sustainability. The aim of this study was to evaluate 116 genotypes of Triticum turgidum from seven countries in terms of morphological traits. The results showed that high significant differences among the genotypes. The correlation between gra...

Correcting Principal Component Maps for Effects of Spatial Autocorrelation in Population Genetic Data

In many species, spatial genetic variation displays patterns of "isolation-by-distance." Characterized by locally correlated allele frequencies, these patterns are known to create periodic shapes in geographic maps of principal components which confound signatures of specific migration events and influence interpretations of principal component analyses (PCA). In this study, we introduced model...
