Phenotyping the PPV resistance Quarantine shelter Greenhouses Commercial and experimental orchards
Evaluation methods GF305 Cultivar rootstock Inoculum Greenhouse Field and Quarantine Shelter
Phenotypic characterization of population PPV Resistance confirmed by genotype and phenotype Floral biology: ‐ Chill requirements, self‐compatibility, etc. Fructification: ‐ Fruit set, productivity, ripening date, etc. Fruit quality: ‐ Weight, color, firmness, sugar content, acidity, etc. Other agronomical traits: ‐ Vigour, growth habit, level of thining…
