Investigation of Pomological and Morphological Diversity of Apple in Sistan region

This research was conducted to determine the characteristics and germplasm grouping of different genotypes of apples grown in Sistan and Baluchestan province. 25 apple genotypes were collected from four regions of Hamoon, Bonjar, Imamieh and Zahedan and morphological and pomological traits were evaluated. Comparison of means of data showed that there was a genetic diversity between the genotypes in terms of quantitative traits, especially the annual shoot diameter, leaf blade length, width of the eye socket and pedicel cavity, pedicel thickness and length, and fruit length and width. The means for these traits were higher in Zahedan genotype than that of Zabol genotypes. In terms of pomological traits, the genotypes had a considerable diversity. Correlation analysis between traits showed a positive and significant correlation between pedicel thickness with pedicel length (0.65), fruit width (0.76), fruit weight (0.48) and also between annual shoots diameter (0.61) with the width of the eye socket (0.83), depth of eye basin (0.84) and fruit length (0.72).
