UCB-1 Pistachio Rootstock

What is UCB-1 Pistachio Rootstock?

UCB-1 pistachio rootstock is   a pistachio clone rootstock created as a result of the P.atlantica X P.integerrima hybrid developed by the University of California Berkeley. UCB-1, which is frequently preferred with a success rate of more than 90%, is a pistachio rootstock with a very high productivity.

Rapidly developing UCB-1 ensures rapid growth of the plant and leads to early yield. UCB-1 pistachio rootstock, which has an extra high productivity due to irrigation, is resistant to soil-borne fungal diseases, Verticillium dahliae, nematodes and salinity, but also tolerates cold. UCB-1, which draws attention as it has the widest planting area in the industrial field and is the most tested rootstock species, is among the quality species among the pistachio clone rootstocks.

What are the features of UCB -1 Pistachio Rootstock?

  • UCB-1 is a P.atlantica X P.integerrima  hybrid pistachio rootstock developed by the University of California Berkeley.
  • It is resistant to soil-borne fungal diseases, Verticillium dahliae, nematodes and salinity.
  • It is among the most preferred pistachio rootstock varieties due to its cold tolerance.
  • Its efficiency is quite high, with a success rate of over 90%.
  • UCB-1 pistachio rootstock, which develops rapidly, becomes surmountable after 3-4 months in spring.
  • It accelerates plant growth and provides early yield.
  • It is a type of pistachio rootstock with a very high productivity due to irrigation.
  • Since it is a rootstock grown in a pot, it provides ease and quality of planting in all seasons and creates durable roots.
  • Finally, the pistachio rootstock UCB 1, which is highly preferred by the producers of our country, also draws attention in terms of being the only cultivated rootstock of the pistachio that can be irrigated.

What is the Canopy of UCB-1 Pistachio Rootstock?

The growth force of UCB-1 pistachio rootstock is higher than P.atlantica , generally equal or higher than P.integerrima . It was determined that the tree crown volume expanded from 3 m 3 to 38 m 3 in the development of the rootstock that was not grafted after planting from 2 to 5 years .

Generally, the tree crown volume increases 3 times up to 3 years after planting, while it doubles for each subsequent year. It increases the branch length and graft stem diameter of the variety grafted on it by 20%.

What are the Soil and Climate Conditions in UCB -1 Pistachio Rootstock?

UCB-1 pistachio rootstock, which draws attention with its superior growth power and rapid plant growth, allows early yield. A rootstock type UCB-1 that is resistant to cold and soil-borne fungal diseases; shows rapid development and rootstocks planted in the field in the spring become graftable after 3-4 months. It is a pistachio rootstock with high productivity due to irrigation. UCB-1 pistachio rootstock is very durable due to its strong structure. It is a species that can tolerate everything except humidity while struggling with temperature differences.

How to Grow for UCB-1 Pistachio Rootstock?

Rootstocks, which are usually grown in pots, provide ease of planting and quality in all seasons, and form healthy roots in peat.

UCB-1 pistachio rootstock is the only cultivated rootstock of pistachio that can be irrigated. It supports the rapid growth of the plant and its rapid yield. Annual shoot length also increases in terms of irrigation. For this reason, they are much more productive than normal trees grown on their own. UCB-1 pistachio rootstock can be easily planted at any altitude except very cold continental climates. After the sapling is planted, it can be irrigated every 25 days, depending on the location and soil structure.

What are the UCB -1 Pistachio Rootstock Grafting Methods?

The graft retention rate of hybrid pistachio rootstock UCB-1, which is a fast growing rootstock, is higher than other rootstock varieties with a success rate of over 90% and the grafting efficiency gives very good results. UCB-1 pistachio rootstock planted in the spring season develops rapidly, becomes graftable 3-4 months after planting, or it is planted in the summer season and grafted in the following autumn.
