Abstract: 

Genetic potential and variation of Jujube (Zizyphus jujuba Mill) ecotypes were investigated. The plants were collected from 15 provinces ofIran with different ecological and geographical conditions and have been evaluated during 1999-2002. Experiments were carried out with 29 ecotypes, using three replicated complete block design in Badiei Station in western part of Qom. Branch angle, stem thorns number, length of longest thorn, length of annual branches, length of annual thorn, border and shape of leaf, length of petiole, length and width of leaf, length and width of new leaf and leaf color were measured. Ecotypes showed significant differences for leaf length and width. Correlation coefficient indicated that branch angle, number of thorn and leaf length together and with other characters had significant correlation. Factor analysis determined four factors that describe 64% of variance. Factor analysis with Varimax method, determined three factors, including leaf shape, new leaf and angle of branch and number of thorn in annual branches. Cluster analysis separated the ecotypes into three groups based on origin sites (Isfahan, Mazanderan and Khorasan). Fars ecotype is originated from Isfahan and Qom ecotype is originated from Isfahan and Mazanderan basis.
