Abstract


An eco-geographic survey covering three eco-geographical regions (Coastal Andhra, Telangana and Rayalaseema) of Andhra Pradesh State, India was undertaken during May-June 2009 to locate, analyse and as¬sess the current status of mango genetic resources. Morphological analysis following descriptive statistics revealed considerable variability among 90 mango cultivars which was confirmed by molecular analysis with109 mango-specific SSRs. Jaccard’s similarity co-efficient ranged between 0.35 and 0.85 signifying a wide range (15-65%) of intraspecific diversity at molecular level in mango. A dendrogram based on application of unweighted pair group method using arithmetic average cluster analysis demonstrated four genotypic groups among the varieties studied.
