Variety traits

Apricot tolerance

Prunus armeniaca L.

The ability of apricot cultivars to maintain productivity and fruit quality under exposure to biotic pathogens, in particular Plum Pox Virus (PPV), as well as Monilinia and Clasterosporium diseases.

In the reference 32 varieties crop Apricot, where this is mentioned in the description.

For apricot, the key aspect of tolerance is the reaction to Plum Pox Virus (PPV). Unlike resistance, this trait allows the plant to limit the negative physiological impact of the virus while maintaining the commercial quality of the yield, even in the presence of an infectious background.

Regarding fungal diseases, such as Monilinia and Clasterosporium, a tolerant cultivar is defined by its ability to minimize yield loss and maintain foliage during infection. The trait is evaluated using symptom intensity scoring scales, comparative analysis with susceptible samples, and the use of SSR markers for genotype selection.

Tolerance to abiotic factors in apricot characterizes the adaptability of cultivars to soil and climatic limitations and high-density planting conditions. The use of tolerant forms allows for the stabilization of production in epiphytotic zones, where the development of immune cultivars is difficult or economically unfeasible.
