Varietats d'Ametller: Vairo


  • Synonym: “Vayro”
  • Breeders’ reference: IRTAMB-A21-323.
  • Breeding number (IRTA almond cultivar breeding programme) : “21-323”.
  • Origin: seedling derived from the cross “4-665” x “Lauranne”, made in 1991
    at Mas de Bover (Constantí, Tarragona).
  • Protected cultivar: Plant Variety Rights pending from OEVV and CPVO.
    Temporary protection granted.nal.

Pomological traits

  • Tree vigour: very vigorous. Its vigour allows to maintain an optimum balance
    between production and vegetative growth.
  • Foliage density: medium.
  • Growth habit: medium.
  • Branching density: medium.
  • Training and pruning: very easy.
  • Nuts location: mainly on spurs, but also on brindles and on one-year old
  • Blooming time: late (similar to “Guara” and “Glorieta”). At Mas de Bover 26
    days after “Desmayo Largueta” (average of 12 years observations).
  • S compatibility genotipe: S9Sf.
  • Pollination: self-fertile cultivar. Cross-pollination unneeded. Self-compatible
    cultivar, with a good autogamous level (capable to produce in isolated conditions).
  • Pollinators: to foster cross-pollination (advisable practice, even for self-fertile
    cultivars), could be combined in the orchard with “Constantí”, “Glorieta”,
    “Francolí”, “Guara”, etc.
  • Blooming density: high.
  • Length of blooming: medium.
  • Bearing precocity: precocious.
  • Cropping capacity: very high.
  • Cropping regularity: good. Low alternate bearing.
  • “Fusicoccum” (Phomopsis amygdali Del.) tolerance: tolerant.
  • Red leaf blotch” (Polystigma ochraceum Whal.) tolerance: very tolerant.
  • Harvesting season: early (at the second half of August at Mas de Bover).
  • Harvesting ease: good. At maturity nuts keep attached to their branches and,
    when shaking, they drop easily.
  • Husking ease: good. The husk is separated easily from the shell.

Commercial traits

  • Nut shape: cordate.
  • Kernel size: medium (1,2 g).
  • Shelling percentage: 29 %.
  • Shell texture: hard.
  • Double kernels: without doubles (0,1 %).
  • Kernel appearance: attractive. Skin smooth and clear, without shrinkels.
  • Blanched kernel composition: oil: 52,7 %; protein: 24,5 %; soluble sugars:
    3,0 %; total fiber: 9,0 %; water: 4,6 %.

Global assessment

It is highly productive due to its considerable bearing intensity and vigour. Self-fertile, (good autogamus level). Late blooming. Easy to train and prune. Produces good kernels. Isis tolerant to “fusicoccum” and “red leaf blotch”. Cross-pollination can be fostered using “Constantí” or other cultivaras having similar blooming time.
