  This research was carried out for evaluating phenotypic diversity and traits correlation in 60 almond genotypes and cultivars in nursery conditions. After preparation land and the bitter seeds of Shahroud22 genotype as seedling rootstocks planted in the autumn 2005. After the seed germination in the spring of the next year, the results of recorded data in 3rd may of 2006 showed that the planted bitter seeds in the nursery had the 90-95 percent of germination. By the end of July 2006, 60 almond genotypes and cultivars in nursery on the considered rootstocks were propagated by budding. The results of recorded data by the end of October 2006 showed %85-90 graft satisfactory. To simplify the study, we gave the code of A1-A60 to 60 genotypes and the cultivars of the almond. Also, the results of obtained data from 9 main vegetative and physiological characters of 60 cultivars and the genotype of almond experimented in clouding the diameter the trunk from the 5 cm above the place of the graft , the height of the plant , the numbers of the branch on the trunk, the number of the leaves on the branch of the current year , the length of the blade of the leaf , the width of the blade of the leaf , the length of the petiole , the amount of the chlorophyll and the contamination by the bloody aphid, in 2007 showed that among 60the cultivars and the genotypes of almond , there was significant difference in the mentioned traits . The biggest diameter of the trunk from upper than 5 cm , the length of the petiole , the percent of the contamination by the bloody aphid, height of the plant, the numbers of the branches on the plant , the numbers of the leaves on the shoot of the current year , the length of the blade of the leaf , the width of the blade leaf , the amount of the chlorophyll were in the cultivars and the genotypes with A16, A5, A39, A24, A1, A16, A43, A2 and A11, respectively and the least diameter of the trunk upper 5 cm, the length of the petiole, the percentage the contamination by the bloody aphid, the height of the plant , the numbers of the branch on the plant , the numbers of the leaves on the branch in the current year , the length of the blade of the leaf, the width of the blade of the leaf , the amount of chlorophyll were in the cultivars and the genotypes with A46, A16, A9, A44, A56, A7, A44, A38 and A29 were observed, respectively. The correlation of the studied traits in 60the cultivars and the genotypes of almond showed that between the length of the blade of the leaf and the length of its petiole at level p <0.01, there was the positive and significant correlation (r=0/63), and this correlation was the most correlation between the studied traits in 60the cultivars and genotypes of almond. تفاصيل المقالة
