Abstract :
Amaranthus retroflexus, is an abnoxious weed and has cosmopolitan ‎distribution. The species is a successful invader and seems to be adapted ‎to a wide array of habitats. In the present study, morphological traits ‎like of plant ‎height, inflorescence length, leaf ‎length, leaf ‎width, leaf ‎‎area, number ‎of ‎leaves and total ‎protein were assessed. Unweighted ‎pair-group method of arithmetic averages method (UPGMA) were ‎performed to determine the individual relationship among ecotypes‏.‏‎ ‎Four groups were classified based on the cluster analysis of ecotypes ‎and factor analysis revealed that three factors comprise almost 78.25% ‎of total variations that the proportion of the first and second ‎components were 51.8 and 25.45, respectively. Leaf length and leaf ‎width possessed the highest positive correlation with the first factor‏.‏‎ ‎Number of leaves and inflorescence length possessed the positive ‎correlation with the second factor. ‎
