UNIFORMITE PHENOTYPIQUE [1 record]

Record 1 2025-12-30

English

Subject field(s)
  • Genetics
  • Plant and Crop Production
  • Agricultural Economics
DEF

Trueness to type or variety, usually referring to seed.

OBS

The terms "varietal purity" and "genetic purity" were once synonyms and are sometimes still used as such but there may be reasons to clearly differentiate between the two. Varietal purity is perhaps best described as relative phenotypic uniformity whereas genetic purity relates specifically to the DNA and RNA of plants.

OBS

Designation used at the Canadian Grain Commission, in the field of cereal terminology.

French

Domaine(s)
  • Génétique
  • Cultures (Agriculture)
  • Économie agricole
DEF

Conformité au type ou à la variété, ordinairement en parlant d’une semence.

OBS

Les expressions «pureté variétale» et «pureté génétique» ont déjà été synonymes et elles sont parfois encore utilisées de la sorte, mais on peut être justifié de les distinguer nettement l'une de l'autre. La pureté variétale se décrit peut-être le mieux par la notion d’uniformité phénotypique relative, tandis que la pureté génétique concerne spécifiquement l'ADN et l'ARN des végétaux.

OBS

Désignation en usage à la Commission canadienne des grains.

Spanish

Campo(s) temático(s)
