Rootpac®40
The series of Rootpac patterns comes from the programme for obtaining new Prunus rootstocks developed between 1996 and 2012.
The search for these patterns focused on responding to the needs of a fruit sector in constant evolution and development towards the efficiency and intensification of plantations.
General information
Species
Hybrid of peach tree x almond (Prunus dulcis x Prunus persica) x (Prunus dulcis x Prunus persica).
Origin
Agromillora rootstock genetic improvement programme.
Agronomic Characteristics
Vigour
Medium, around 25–30% less than GF–677, although with a well-developed root system.
Compatibility
Good with varieties of peach, nectarine, almond and some varieties of Japanese plum.
Structure
Erect, similar to Garnem.
Yield
Highly productive.
Size
Anticipates ripening by 3 to 7 days depending on the variety. Produces good-size fruit.
Adaptability
It adapts very well to all climates, but especially to warm conditions (low chilling area).
Other features
Green leaf rootstock. Rigid stems (early lignification) with little or no branching in early development stages. Easy handling in nursery.
Resistances and tolerances
Chlorosis
Moderately tolerant. High requirement of microelements
Root-knot nematodes
Moderately tolerant
Agrobacterium tumefaciens
Sensitive
Rosellinia necatrix
Under study
Root asphyxia
Similar tolerance to root asphyxia as the most peach and almond tree hybrids.
Salinity
Moderately tolerant
Root-lesion nematodes
Susceptible
Armillaria mellea
Sensittive
