Abstract

Background and Objectives: MULBERRY (Morus spp. L.) is one of species belong to Moraceae family. There are twenty-four species of Morus and one subspecies, with 100 known varieties. The various methods used in classification of Morus were mainly based on the conventional systematic studies and agronomic characters. Despite the widespread genetic diversity in Iranian MULBERRY, so far, the identification of these plants have not been selected, and introduce for cultivation. Field expeditions were carried out in 2008 and 2014. Collections were made from different regions (Tehran, Mazandaran, Kurdistan, Markazi, Khuzestan, Fars, West Azarbaijan, Isfahan, Hamedan, Khorasan, South Khorasan, Semnan, Ardabil, Kohgiluyeh and Boyer-Ahmad, East Azerbaijan) in Iran. Characterization of leaf and fruits was based on Morus descriptors developed by the International. Plant Genetic Resources Institute (IPGRI). The aim of this study was evaluation of genetic diversity and MULBERRY clustering genotypes, on the basis and quantitative traits and to determine the genetic distance among studied genotypes.Material and Methods: MULBERRY trees are widely distributed in Iran. 118 samples selected from MULBERRY population based on descriptor developed by International Plant Genetic Resources Institute (IPGRI) were evaluated for their morphological trait. The quantitative and qualitative traits were measured according to International Union for the Protection of New Varieties of Plants (UPOV). When the data was denoted through descriptive statistics, were conducted. The analysis of variance with the PROC GLM procedure was applied to distinguish the effect of the genotype into treatment and regions within each area as replication on the analyses traits. The mean separation was conducted through the LSD test.Results: Results reflected a significant diversity in the assayed MULBERRY germplasm. It was noted that the characteristic trait of leaf margin, petiole length, and flower diameter were reflected higher coefficients of variation that were higher diversity among investigated genotypes. Therefore, there is the possibility of selecting genotypes for different values of an attribute. All other related traits with high coefficients of variation are more diverse than other trait, which reflected low variable. coefficient variation value.Discussions: The value of the CORRELATION coefficient (r) was noted to be positive significant for the harvest time of fruit ripening (r = 0.82, P<0.001), the shape of inflorescence at the time of fruit ripening (r=0.71, P<0.001). Some value CORRELATION obtained for 'Brix' versus time of fruit ripening (r= 0.60), Brix and fruit shape (r=0.28), fresh weight vs. the time of ripening (r= 0.81), which were found to be positive at 5% level. The result indicates that the fruits are harvested almost simultaneously ripened in a long time unlike other fruits. Clustering (Ward linkage) based on morphological trait clearly separated genotypes into three main groups. Principal component analysis (PCA) was used to determine the morphological distinction between the populations. The first component contributed 0.65% the total variation contributed by all traits. Overall, the results showed that great morphological variation among the plant population.
