Variety traits

Yield of hybrids between Citrus x aurantium L. x Citrus trifoliata L.

Hybrids between Citrus x aurantium L. x Citrus trifoliata L.

These hybrids are primarily used as rootstocks; therefore, their productivity is assessed indirectly through their influence on the yield of the grafted scion. The fruit quality metrics of the hybrids themselves are not considered commercial.

In the reference 6 varieties crop Hybrids between Citrus x aurantium L. x Citrus trifoliata L., where this is mentioned in the description.

The primary purpose of these hybrids in citrus cultivation is their use as rootstocks, as their fruits have poor taste qualities and are not considered a commercial product. Yield in this case is measured not by the fruits of the rootstock itself, but through the productivity of the scion.

Key evaluation criteria include the mass and number of fruits on the scion tree, as well as the yield efficiency index, calculated as the ratio of crop mass to the volume or projection area of the canopy. The values of these indicators are determined in comparative trials against control rootstocks under specific soil and climatic conditions.

The choice of hybrid as a rootstock has a direct impact on the vigor, precocity, and fruit size of the scion, as well as its resistance to the tristeza virus and environmental stress factors. Characteristics of the rootstock can alter the tree volume, which requires adjustments to planting density to maintain target orchard productivity levels.
