Analysis performed with STRUCTURE software. Lb-1: Library constructed from a sexual accession (H031), Lb-2: Library constructed from a pool of eight apomictic accessions, Lb-3: Library constructed from an apomictic accession (H016) [12], Lb-c: Joint analysis of Lb-1 and Lb-2, Lb-ct: Joint analysis of Lb-1, Lb-2, and Lb-3. Each of the 34 genotypes is represented by a single column divided into colored segments with lengths proportional to each of the allelic pools inferred by K through Evanno method [24]. Each K is represented by a different color and Lb-1 presented K = 18, Lb-2 K = 17, Lb-c K = 17, Lb-3 K = 15, and Lb-ct K = 18. The individuals were grouped into clusters according to the Q proportion of each allelic pool in an individual. Eight clusters were identified for Lb-1, Lb-c, Lb-3, and Lb-ct (I to VIII) and seven clusters for Lb-2 (I to VII). The left scale indicates the association coefficient (Q) for the assignment of genotypes into groups. The genotypes are named according to the annotated numbers listed in Table 1.
