Mango Genotype Diversity and Determination of Quantitative and Qualitative Characteristics of 5 Mango Superior Genotypes in Southeastern region of Iran

Mango is one of the most important tropical fruits being cultivated for a long period in southeastern region of Iran. In orchards, most of mango trees are cultivated by seeds, and as consequence they show genetic diversities. Thus, the majority of the crops are of low quality and do not have good marketing place. Also, the diversity in tree features causes serious difficulties in managing gardens and endures costly expenses for gardeners. This study was performed for evaluation and comparison of 5 Mango superior genotypes in a randomized complete block design that was conducted in 4 replicates and each treatment consist of 3 grafted trees. The specified distance was 8×8 m. Data was analyzed from 2009 to 2011 showed that the tree height in different genotypes were not significant. However, significant differences in the shoot diameter (canopy) of different genotypes were measured. For example, the shoot diameter of genotype number 8 which showed the highest (360 cm), and those of genotypes number 59 and 27 (263 cm and 238 cm) were the lowest, respectively. A significant difference at 1% level has been observed between trunk diameters above the graft union.
