Morphological characterization and genetic diversity analysis of Tunisian durum wheat (Triticum turgidum var. durum) accessions

Table 5 Means of morphological traits calculated for Azizi and Mahmoudi accessions from the center and the south of Tunisia and for all accessions from C1 and C2 clusters. Means with distinct letters show significant differences at 5% threshold between center and southern accessions
