Rootstock breeding is a discipline that takes a very long time compared with variety breeding. For this reason, some chemical indicators and morphologic markers are used to identify important characteristics in the early stages of plant development. In this study, we investigated whether there was a relationship between plant vigor, which is one of the important features in rootstock breeding, and the amount of lignin in the cortex. Twelve genotypes were used in this study. The level of lignin in the cortex, the lengths of internodes, and the bark/wood ratio were correlated with stem diameter and length in these genotypes. The amount of lignin in the cortex was determined using histologic methods. A positive regression was found between lignin level in the cortex and stem diameter and plant length. It was concluded that adding a positive correlation between the amount of lignin in the cortex and the vigor of the plant to the traditional methods of rootstock preselection in the early period of plant growing will contribute scientifically to rootstock breeding studies.
