THE STUDY OF MORPHOLOGICAL DIVERSITY AMONG SOME OLIVE GENOTYPES IN NORTHERN IRANAREZOO JALALI1, ESMAEIL SEIFI, MEHDI ALIZADE AND HOSEIN FEREIDOONIAbstract Iran is renowned as one of the olive origins in the world; therefore, characterizing and conserving the genetic resources, characterizing the old olive orchards and organizing the existing genotypes are of critical importance. This investigation aimed to evaluate morphological characteristics of some olive genotypes in Hashemabad collection in Gorgan, Iran. To do so, 31 genotypes were studied in completely randomized design with three replications. The results revealed that there were significant differences between genotypes in terms of the measured traits. C10 had the highest fruit weight. K9, E5, C9, A11, E1 and K10 had the highest percent of flesh. The highest ratio of length to width of leaf was seen in J13. The most flower density was observed in A2. Clustering based on properties of fruit and stone showed high similarity between the genotypes, and assigned them in four main groups. Correlation coefficient between the characteristics suggested that there were some significant correlations among a number of measured characteristics. A significant and positive correlation was observed between fruit weight and leaf length/width and inflorescence length.
