Evaluation of diversity seed storage proteins and some morphological traits in various species of Papaver

This experiment was conducted to evaluate the seed storage protein of seven different species of Papaver in Ardabil Province, Iran by SDS-PAGE method. By scoring banding patterns data, a total of 20 loci were identified in the species. Maximum number of protein band (17 bands) was belonged to P. bracteatum and P. rhoease. Minimum number of protein band (13 bands) was related to the species of P. argemone and P. somniferum. Cluster analysis based on Jaccard's similarity matrix classified different species in four groups. Different species of papaver were classified as follows: P. somniferum in the first group, P. orientale, P. bracteatum, P. lasiotrix and P. rhoease in the second group, P. dubium in the third group and P. argemone in the fourth group. Different species showed a good variety with regard to the morphological traits (petal color and shape, seed color and size and plant height) and the species were classified in three separate groups based upon cluster analysis. Mantel test was performed to examine the correlation of morphological data with seed storage proteins. This test did not show significant correlation between these two groups of data possibly due to the low number of morphological traits and low number of molecular markers.
