Morphological characteristics and variation of three species of Medicago

Morphological characteristics of 3 species of Medicago(Medicago sativa,M.falcata and M.varia) were studied and the various morphologic variance were found among the 3 species.The most significant differences were found in the leaf area and leaf width.Correlation analysis indicated that all parameters related morphological features were correlated each other except node number and average internode length.Principal component analysis indicated that the main morphological variance among 3 specie were from the stem length,node number,average internode length and leaf width.
