Abstract

In this experiment 29 genotypes of walnut (Juglans regia) were studied, based on Randomized Complete Blocks Design (RCBD) and four replicates. The experiment was conducted in Rikhalan Experimental Station of Marivan.  City through three years (1996 – 1998). The results showed that there were significant differences between the walnut genotypes for survival percentage, height and collar diameter performances. The highest value of the three seedling performances belonged to the following walnut genotypes:  Survival: J-19 with 50.75 percent.  Height: J-10 and J-19 with 35.52 and 34.87 cm, respectively.  Collar diameter: J-14, J-19, J-4 and J-10 with 6.52, 6.47, 6.3 and 6.2 mm, respectively.  According to Cluster Analysis Statistical Method, J-19, J-10 and J-14 were the most successful genotypes in view point of the three seedling performances.  The above genotypes were introduced to the second phase of the trial, which aims to investigate the survival and growth of the genotypes at forest plantation scale.
