Figure 2From: Single nucleotide polymorphisms for assessing genetic diversity in castor bean (Ricinus communis)Genotypes of Ricinus communis from nuclear SNPs were best described by five genetic clusters in a worldwide collection of 488 germplasm samples. Group colors correspond to Fig. 1 and circle sizes represent relative number of samples. Samples were only considered in a particular group if they meet a 60% threshold of group assignment. Thus, not all samples were assigned to a group because they shared affiliation with several different groups.Back to article page
