In order to evaluation and determine the best rootstock and cultivar combination for growth of 9 selected strains of mass washington navel on 3 rootstock( Sour orange, Citrange & Poncirus) in Astara research station, this experiment was conducted. This experiment was carried out as factorial in a randomized complete bloke design whit seven replications. Results of analysis of variance and mean comparison showed that the heightest trunk diameter and tree height growth, and the lowest trunk diameter and tree height growth were in A strain on citrang rootstock and E strain on poncirus rootstock respectivly. The highest canopy growth was in G & H strains on poncirus rootstock and the lowest growth was in B strain on sour orange rootstock. Results showed that canopy growth in some strains on poncirus rootstock were higher and annual shoot growth were lower than other two rootstocks. Results indicated better compatibility A, I strains on citrange rootstock from height and trunk diameter growth point, and F strain on poncirus and I strain on citrange from precocity and vegitative growth point.
