In citrus despite the diversity among cultivated genotypes related to morphological, physiological, and agronomic traits, low polymorphism is detected at the molecular marker level, and the number of DNA-markers technologies has been insufficient to identify genetic diversity among all citrus varieties. However, DArT_seq™ markers can overcome this limitation and identify genetic diversity in several species of citrus. This work developed and applied DArT_seq™ platform to study the relationships among species, cultivars, and hybrids of citrus. DArT_seq™ yielded a total of 37,260 polymorphic presence/absence markers that generated a dendrogram of similarity among the studied genotypes. The results confirmed the relationships of sweet orange, mandarin, and citron species. DArT_seq™ markers showed extensive genetic variation among citrus species and can be applied to Citrus genetic diversity studies. [ABSTRACT FROM AUTHOR] |
