Evaluation Morphological Characteristics and Phenotypic Diversity some of ‎Dwarfing Chrysanthemum (Dendranthema grandiflorum Tzvelev.) in ‎Khorramabad conditions

Chrysanthemum (Dendranthema grandiflorum Tzvelev.) is one of the most popular pot and cut flower crops throughout the world. The genetic diversity assessment among present Iranian Chrysanthemum cultivars are needed for future Chrysanthemum breeding programs. This study aimed to assess the Phenotypic Diversity of in 15 dwarf cultivars Chrysanthemum, based on morphological characteristics and selection of suitable cultivars for planting in the beauty of green spaces and parks in randomized complete block design with three replications at the agricultural research station of lorestan university in Khorramabad were conducted. The results obtained from this study indicated that wide range of variations among cultivars studied, In terms of traits were measured. some of traits such as flowers number, number leaves and number of florets tab showing higher co-efficient variation, there were more variations among the chrysanthemum cultivars. Results correlation coefficients showed that there were negative correlation between leaf width with leaf length, petiole diameter and leaf area. Factor analysis, showed six independent factors with specific values than a total of 83.4 justify the total variance. In Cluster analysis, cultivars in Euclidean distance of 28.11 were divided into three groups. Two cultivars ' Avadis' and ' Nastaran' Were known with height 30.33 and 37.33 cm, In the group dwarf cultivars respectively and are Suitable for potted chrysanthemums. Therefore, evaluation these cultivars in the same conditions can be done selection for studied traits.
