Varietats d'Ametller: Vairo

Description

• 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
  shoots.
• 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.
