In pistachio cultivation, the choice of rootstock as the root system Iranian Pistachio of the plant is very important.

 

In Iran, three bases of P. vera (domestic pistachio), P. khinjuk (Chatlanqush) and P. mutica (pistachio) are used for pistachio cultivation. The use of 2 stems of pistachio and chrysanthemum in Iranian pistachio orchards is very rare and in more than 99% of the country"s pistachio orchards, domestic pistachio rootstocks are used. The base of domestic pistachios grown in Iran is usually almond Zarand. After planting the base and reaching the age of grafting, the desired cultivars are grafted on it. One of the important characteristics of pistachio rootstock is resistance to pistachio root-producing nematode. It is said that the base of Chatlanqush has good resistance to drought.

 

In other countries of the world, the bases of P. terebintus, P. atlantica, P. integerrima, UCBI, PGI and PGII are used. The three bases UCBI, PGI, and PGII are the result of breeding programs and the cross between P. atlantica and P. integerrima.

 

P. atlantica rootstock is one of the most common rootstocks used in California due to its high resistance to cold. The problem with this base is susceptibility to Vertilicium disease. Recently, the use of P. integerrima rootstock has been strengthened in breeding programs due to its resistance to Verticillium wilt.
