Int. J. Nuts Related Sci. Vol. 1, No. 1, Summer 2010, pp. 30-40 Phenotypic Correlation between Some Nurserphelogical Traits among 60 Cultivars and the Genotypes of Almond A. Imani Horticultural Department of Seed and Plant Improvement Institute (SPII), P.O. Box31585-4119 Karaj, Iran Abstract 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. Key words: the phenotypic diversity, the correlation of the traits, almond and the nursery. 30 Introduction (Barbera et al., 1994). The study of the reaction Iran is one of the most important centers of the of 24 cultivars of the self fertility almond in the plantation and the production of almond in the ecological condition of the South Eastern of world. In Iran, almond has the relatively good French have showed that among 24 cultivars, two benefits because of the suitable ecological cultivars of Steliette and Lauranne were selected conditions and its resistance to the drought and as the best self- compatible cultivars from the the calcareous conditions. Also, the trees of point of view of the habit of the growth, the late almond have the long age about 20-40 years, and flowering and the excellent performance (Duval they begin to bear fruit since 3-4 years old. So and Grasselly, 1994). besides the selection of the suitable place of the The study of the bioagronomical reaction of 22 orchard and its management, we must pay famous cultivars of the world in Italy showed that attention to select the suitable cultivar carefully. the late flowering cultivars have better efficiency The recognition and the evaluation of the in the years that there was late frost of the spring genotypes of almond can be base for the future and the index of the fertility was higher in the studies and for obtaining the desirable cultivars cultivars of the self compatible with the adverse or the cultivars having the special traits including conditions of the pollination (Viti and Loreti, habit of the desirable growth , the resistance to 1994). The study 30 superior genotypes and the coldness or the pest or the diseases (kester et cultivars in California showed that the cultivars al., seedling and the genotypes be have differently because of rootstocks and recognizing the cultivars have one the vegetative traits particularly the habit of the or some excellent traits and their usage in the growth (Ledbetter and Palmquist, 2002). The programs of the breeding and the cropping is evaluation of the biotic diversity of 88 cultivars very and the genotypes of almond in the collection of 1991).Obtaining important the (Kester suitable and Asay, 1975; Grasselly, 1986). the university of Bari in Italy showed that the Beside the recognizing and collecting the cultivars superior genotypes among the native population reproductive and vegetative traits have the (seedling orchards) of almond and also making different characteristics and these diversity new indices are very important hybrids , the evaluation and their and genotypes because of the comparison along with the important and in helping to choose of the breeder( De Giorgio commercial cultivars to obtain the cultivars with and Polignano, 2001).Lansary et al. (1994) could the desirable traits can make the great change in obtain the indices to distinguish the present the industry of almond .So ,the study of the cultivars and the present closes in the collections reaction of two cultivars of almond named of almond of California by the analysis of Ferragnes and Tuono along with 50 cultivars and multivarians genotypes in the ecological condition of the morphological parameters .The study of the South Italy showed that the phenological traits history of the search in Iran also shows that some and performance of cultivars have been different cultivars are better than other cultivars in the of the biochemical and the experimental conditions , so in the primary study studied in a similar environmental condition of of the native and foreign cultivars in the Station the nursery. For this, after providing of the field of Sahand after 14 years of studies revealed one and its preparation, the bitter seeds were planted native cultivar Sahand and 5 foreign cultivars ( in the autumn of 2005 in the nursery to produce Nonpareil , Ne Plus Ultra , Ferragnes, A 200 and the necessary seedling rootstocks. After the seed A230) and 2 hybrid ( Azar and Shokoufeh ) as germination in the spring of the next year, in 3rd the superior cultivars .Also study of some May of 2006, percent of germination of planted commercial Shahrekurd(Rabie, bitter seeds in the nursery was recorded. By the Mamaie and Sefid cultivars), shahrood (Shahrood end of July 2006, 60 almond genotypes and 12, 15, 16, 17, 18 and 21) and Karaj [(Genco, cultivars in nursery on the considered rootstocks Falsa Bares, Philip Ceo, Feragilo, Super nova and were propagated by budding. Percent of graft Tuono imported from Italy as the self compatible satisfactory recorded by the end of October 2006. cultivars and Marcona as self incompatible To simplify the study, we gave the code of A1- cultivar from Spain) and 35 superior selective A60 to 60 genotypes and the cultivars of the genotypes from almond breeding programs in almond (Table 5). Also, the results of obtained Karaj (specially resistant to the cold)] showed data from 9 main vegetative and physiological that some cultivars had performance better than characters of 60 cultivars and the genotypes of other cultivars((Imani et al, 2006). But up to almond experimented in clouding the diameter now, inside the country about the phenotypical the trunk from the 5 cm above the place of the behavior of these almond cultivars in a similar graft , the height of the plant , the numbers of the environmental condition of the nursery haven’t branch on the trunk , the number of the leaves on been performed, because in some of the cultivars the branch of the current year , the length of the of almond, they are used as the suitable seedling blade of the leaf , the width of the blade of the rootstock due to the habit of the vertical growth leaf , the length of the petiole , the amount of the and being the single trunk and good characters chlorophyll and the contamination by the bloody other. The aim of this study was to consider the aphid were recorded in 2007. In order to phenotypic behavior and the correlation of the evaluation of characteristics of 60genotypes and traits of 60 genotypes and the selective cultivars cultivars, 10 samples of plants were used for of almond in the similar conditions of nursery. every genotype and cultivar by3 replication. cultivars in The statistical analysis was performed using Materials and Methods Microsoft Excel (2007) and SPSS (14.0) The research works of this study were begun by Statistical Software. preparation and the plantation of the bitter seeds of Shahroud22 genotype as rootstock seedlings in Results and Discussion the autumn 2005. In this research for the The results of obtained data from 9 main phenotypic diversity, the number of 60 superior vegetative and physiological characters of 60 genotypes and the cultivars of the almond were cultivars and the genotypes of almond experimented in clouding the diameter the trunk chlorophyll , the contamination by the bloody from the 5 cm above the place of the graft , the aphid , the color of two end leaves and the color height of the plant , the numbers of the branch on of the tip of the branch were shown in tables 1, the plant ,the number of the leaves on the branch 2.3and 4.

The results of the correlation of the studied traits in 60 cultivars and genotypes of almond have been shown in Table3 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 60 the cultivar and genotype of almond. Also the correlation of between the length of the leaf and its width of the leaf was positive (%49.15) that showed important leaf and its area in increasing assimilation in fruit, because of most almonds with larger leaves have bigger fruits (Kester and Gradziel, 1996; Ledbetter and Palmquist, 2002; De Giorgio and Polignano, 2004).
