Principal component analysis (PCA) and the second-degree relatedness in avocado germplasm collection. PCA based on identity by state (IBS) of the core sets was performed using the SNPRelate R-package. The rest of the accessions were projected on the PCA space. Additionally, identity by descent (IBD) analysis were performed to detect the level of relatedness. Accessions related to each other with a kinship coefficient ≥ 0.25 are connected by edges
