ABSTRACT

In this study, genetic diversity in 19 citrus cultivars was analyzed using Simple Sequence Repeat (SSR), Inter-simple Sequence Repeat (ISSR) and cleaved amplified polymorphic sequence (CAPS) markers. Nine primers for SSR, nine ISSR primers and two primers for CAPS were used for allele scoring. One chloroplast DNA region (rbcL-ORF106) and one mitochondrial DNA region (18S-5S) were analyzed using cleaved amplified polymorphic sequence (CAPS) marker in 19 citrus accessions grown in Iran. In total, 45 SSR and 131 ISSR polymorphic alleles and tree organelle genome types were detected. Cluster analysis of SSR and ISSR data was performed using UPGMA method and based on Jaccard's coefficient. The result of this investigation showed that the SSR and ISSR primers were highly informative and efficient in detecting genetic variability and relationships of the citrus accessions. And CAPS marker analysis Results showed that Bakraee and one of off type Mexican lime had banding pattern similar to Clementine Mandarin, while Pummelo regarded as maternal parent of other studied genotypes Citron regarded as father parent showed definite banding pattern among 19 studied genotypes which it confirmed Cytoplasmic inheritance from mother cellular organelles.
