Principal Rootstock

Increased precocity, decreased vigor, productive stability, uniform orchards, best size and quality of fruit, among others, are part of the main objectives to be achieved when deciding which rootstock will be used in a new stone fruit plantation. In order to meet our customers’ requirements, Univiveros® has the following rootstocks available:

Clonal with red leaves. Homogenous behavior and compatible with varieties of peach, nectarine, and almond (extensively tested with European varieties).

It is good for replanting conditions and for drying, low fertility, or calcareous soils. It tolerates asphyxiating or heavy soil and is moderately resistant to nematodes of the Meloidogyne genus.

Generic peach rootstock highly used in Chile for almost all species, except European plum. Resistant to Meloidogyne spp. and sensitive to Pratylenchus.. Widely adapted to different soil types, except in asphyxiating or replanting conditions.

It’s somewhat tolerant to Agrobacterium and sensitive to Armillaria, Verticillium, and Phytophthora.

Clonal. Compatible with most varieties of peaches, nectarines, almonds (widely used with European varieties), and some varieties of Japanese plum. Very good behavior under replanting conditions, and in very drying, low fertility, or calcareous soils, (tolerates up to 15% active lime).

It does not tolerate heavy or asphyxiating soils. It is sensitive to nematodes (Meloidogyne spp.) and to neck gall/crown gall.

Clonal. Compatible with most varieties of peaches, nectarines, plums, and apricots. It adapts well to heavy soils, saline soils, or soils with a high content of carbonate. Especially suitable for replanting or soil fatigue. Induces a rapid entry into production and high productivity.

It is immune to nematodes of the Meloidogyne genus, tolerant to damaging nematodes and more resistant to Agrobacterium than peach rootstock. Emits shoots.

Clonal. Compatible with apricots, Japanese and European plums. Resistant to root suffocation, with good adaptation to all types of terrain. It has low sensitivity to chlorosis, nematodes, and bacteria.

It has a remarkable resistance to root rot.

Clonal. Compatible with most cultivars of peaches, nectarines, and plums.

It adapts well to heavy soils. Tolerates soils with high carbonate content (up to 7.5% active lime). Especially suitable for replanting or soil fatigue in heavy soils. Although it has no specific resistance to nematodes, it is not particularly affected by them.

It is productive and precocious.

Type of Plants

Variety developed for an entire season on two year old rootstock. Plant with large root mass and good reserves. Mostly used for plums, apricots, and almonds.

Variety developed from a bud grafted in spring, on one year old rootstock. Medium sized plant that grows with lots of sun in a nursery, facilitating the formation of the plant in the orchard. It requires more initial attention, especially in irrigation during the establishment of the orchard. It can be used for any kind of stone-fruit.

Variety grafted with two undeveloped buds, on one year old rootstock. Plant with good root system with plenty of fine roots. The graft grows in the orchard with vigor and balance, facilitating its formation. Widely used for peach and nectarine trees.

Plant in 3 lt. container, grafted in late winter and delivered once the variety has grown 40 to 60 cm, which takes place in the months of October and early November.

Plants carry 100% of their roots and the variety grafted on each plant, producing very homogeneous orchards.


Good orchards start with homogeneous plants.

UNIVIVEROS has adopted the North American system of segregation.

In addition to the care taken in regard to our sources of propagation materials, we have a rigorous system of labeling of propagating material which results in coded records of the variety’s identity and origin of each of the plants propagated throughout the production process.
