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 assess 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 with 109 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.
