Abstract

The morphological diversity and relationship among 138 pear genotypes, including 11 commercial cultivars and 127 wild pear accessions from central Zagros mountains located in the west of Iran, based on 64 morphological characters were studied. The higher coefficient of variation indicated that high level of variation was belonged to the petiole stipule, fruit the relative area of the skin color, fruit relative area periphery rust dents end, fruit relative blight on an area of skin, fruit curved tail, fruit dents end, fruit depth dents end, fruit relative area periphery patina tail connection characters. Pyrus communis L. and Pyrus glabra Boiss. species were the highest and the shortest tree, respectively. According to the cluster analysis, 138 genotypes were clustered into nine main groups. Principal components analysis revealed that the first three components accounted for 68.77 % of the total variation in data. Moreover, 19 factors justified 72.57 % of the total variation based on factor analysis. The research results showed that the Zagros mountains are the centers of diversity of pear. Therefore, it is necessary to use the Iranian genotypes as the genetic resources for improving the morphological characters of pear.
