Abstract

This research was carried out to study the relationship between different populations of several medic species based on morphological characters and to determine the best character for detection of genetic variation between the species and populations, in order to prepare basic information required for breeding projects as well as primary assesment of the medic populations.
In this study eleven  populations of annual medic belonging to seven species from Gene Bank of Natural Resources of Research Institute of Forests and Rangelands were prepared. Nine characteristics were recorded from five single plants in every experimental plots. Averages of these data were used in this paper. Then corrolation analysis was performed between all combinations of the characters, using principal components analysis. The role of each character was determined in the available variation of the data. Several principal components were produced to identify the nature of the variations as well as ploting the first two components to visualize the relationship between the populations. Cluster analysis was also used for grouping and clustering the populations for the same purposes.
