ROOTPAC® SERIES ROOTSTOCK

ROOTPAC® 20

General information

  • Species: Plum tree hybrid (P. besseyi x P. cerasifera).
  • Origin: Agromillora rootstock genetic improvement programme.

Agronomic characteristics

  • Vigour: Low, around 40–50% less than GF–677.
  • Compatibility: Good with varieties of peach, nectarine, Japanese plum and almond. Compatible with some varieties of apricot, although more information is needed about its affinity with more varieties.
  • Structure: Erect and compact.
  • Yield: High.
  • Size: Results in very good fruit size and quality. Advances ripening in most varieties.
  • Adaptability: Very adaptable to all production conditions, both in warm and colder climates.
  • Other features: Ideal for SHD high-density plantations. Good adaptation to heavy soils and colder areas.

Resistances and tolerances

  • Cold: Tolerant.
  • Chlorosis: Moderately tolerant.
  • Root-lesion nematodes: Moderately tolerant.
  • Agrobacterium tumefaciens: Sensitive.
  • Rosellinia necatrix: Moderately tolerant.
  • Chlorosis: Moderately tolerant.
  • Root asphyxia: Highly tolerant.
  • Salinity: Moderately tolerant.
  • Root-lesion nematodes: Sensitive.
  • Armillaria mellea: A certain degree of tolerance is sensed.

ROOTPAC® SERIES ROOTSTOCK

ROOTPAC® 40

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: High.
  • 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 cold areas.
  • 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

  • Cold: Tolerant.
  • Chlorosis: Moderately tolerant.
  • Root-lesion nematodes: Moderately tolerant.
  • Agrobacterium tumefaciens: Sensitive.
  • Rosellinia necatrix: Moderately tolerant.
  • Chlorosis: Under study.
  • Root asphyxia: More tolerant to root asphyxia than most peach and almond tree hybrids.
  • Salinity: Moderately tolerant.
  • Root-lesion nematodes: Susceptible.
  • Armillaria mellea: Under study.

Vigour with respect to Garnem*

* The data are obtained from different geographical areas (Tarragona, Murcia and Seville) for the 2005 and 2007 harvests.

ROOTPAC® SERIES ROOTSTOCK

ROOTPAC® R

General information

  • Species: Plum x almond (Prunus cerasifera x Prunus dulcis) hybrid.
  • Origin: Agromillora rootstock genetic improvement programme.

Agronomic characteristics

  • Vigour: High with varieties of peach, nectarine and plum. Similar to Mariana-2624.
  • Compatibility: Good with varieties of plum, peach and nectarine. It has also
    proven to be compatible with some varieties of almond and apricot.
  • Structure: Open, with medium ramification.
  • Yield: High.
  • Size: Anticipates ripening by 2 to 5 days depending on the variety. Results in good fruit size in plum, peach and nectarine.
  • Adaptability: Very adaptable to various climatic conditions, with different cold requirements. Ideal for replanting sites. Adapts well to dense and asphyxiating soils.
  • Other features: Green leaf rootstock, with appearance between plum and almond tree. Rigid and erect stem in early development stages.

Resistances and tolerances

  • Cold: Tolerant.
  • Chlorosis: High tolerance.
  • Root-lesion nematodes: Highly tolerant.
  • Agrobacterium tumefaciens: Unknown, although it is probably sensitive, like most plums.
  • Rosellinia necatrix: It has been shown to be resistant in sites highly infested with this soil fungus.
  • Root asphyxia: Tolerant to root asphyxia. Similar to Mariana-2624.
  • Salinity: Under study.
  • Root-lesion nematodes: Lightly
    susceptible.
  • Armillaria mellea: Unknown. High survival in replanting soil suggests that it has tolerance.
