Evaluation of Quantitative and Qualitative Characteristics of Persian Walnut (Juglans regia L.) Genotypes in the West of Meshkin-Shahr

The Persian walnut (Juglans regia L.) is one of the most valuable resources in Iran because of its multi benefits. The present study was conducted in Meshkin-Shahr in Ardabil province to investigate the important quantitative and qualitative characteristics of 31 walnut genotypes. Classification of genotypes was analyzed using the cluster method. The results showed that among selected walnut genotypes, SS genotype had the highest kernel weight (7.03 g), and fruits weight (12.65 g), and RM3 had the best kernel percentage 63.73%. The walnut genotypes were clustered into three groups using UPGMA cluster method. This preliminary study demonstrated that quantitative and qualitative characteristics were effective in evaluating the genetic diversity of walnut genotypes.
