In this experiment, 32 female varieties and 27 male genotypes in pistachio plantation areas of Kerman, Rafsanjan, Sirjan and Shahrbabak were used. After artificial cross between 32 female varieties with a male genotype and 27 male genotypes with &ldquoFandoghi&rdquo, the obtained hybrid seeds were sown and the produced seedlings tested under saline conditions in glasshouse. After salinity tests, the following characteristics were measured and evaluated: Number of alive seedlings, Number of alive leaves, length of stem, dry weight of aerial organs, dry weight of root and mineral elements of root and stem were analyzed. The data were analyzed statistically in a completely randomized design with three replicates.The results indicated that the female varieties included: &lsquoIbrahimi&rdquo, &ldquoSirizi&rdquo, &ldquoJandaghi&rdquo, &ldquoPoustkaghazi&rdquo, &ldquoFandoghi-48&rdquo&ldquoBadami_e_Zarand&rdquo, &ldquoSeiffadini&rdquoand &ldquoSarakhs&rdquoand genotypes: M27, M10, M16, M21, M23, M25 and M26 are salt tolerant.The result of cluster analysis arranged female varieties in 3 main groups and male genotypes in 4 main groups. The results of contingent analysis indicated that the sodium content of stem with aliveness of seedling is negative contingent and significant, and also accumulation of sodium and magnesium ions in root and stem caused desiccation of leaves in seedlings and reduction of weight in root and stem.
