Behavior of Some Early Mature and Dwarf Persian Walnut Trees in Iran
According to the frequent existence of precocious (early mature) and dwarf walnut genotypes in Iran nurseries, a series of field and laboratory trials were conducted to evaluate these valuable genotypes from various aspects including consistency of growth under in vitro and in vivo conditions and impacts of seedling vigor on the walnut rooting and grafting.Results showed genetic stability of evaluated genotypes, moderate to high narrow-sense heritability (0.39-0.88) for traits related to seedling vigour, positive correlation between seedling height and other vigor related traits as well as desirable effect on the rooting of layers/microshoots both in field and in in-vitro trials and dwarfing effects on scion growth.A selection program for both dwarfing and rooting ability (selection of dwarf/semi-dwarf as well as easy-to-root clones) to utilize their advantages in a high-density orchard system has been suggested.
