Evaluation of morphological diversity of Fritillaria (Fritillaria imperialis L.) in five regions of Lorestan province

In order to study of genetic diversity of Fritillaria populations (Fritillaria imperialis L.), in the five regions of Lorestan Province, used 40 morphological characteristics. Generally, 140 samples from five regions of the three cities including: Khorramabad, Aligudarz and Dorud were collected and analyzed in spring 2014 and 2015 for two years. From each area 30 samples were studied. These results showed that there is significant difference between populations of morphological characteristics. The results of cluster analysis using Ward method and Euclidean distance grouped the samples to five populations. Based on Principal Component Analysis (PCA) results, there were 10 factors that explained 85.34 % of their biological variations. In the first component, threre was positive and high coefficient in length of upper and middle leaf. The classification of cluster analysis was confirmed by principal component analysis. According to this study morphological traits can apply to assess variation among populations of Fritillaria.
