Hybrids between Citrus x aurantium L. x Citrus trifoliata L.
Hybrids between sour orange and trifoliate orange, known as citradias, are used as rootstocks to combine the cold hardiness and tristeza immunity of trifoliata with the adaptability of sour orange.
In the reference 27 varieties crop Hybrids between Citrus x aurantium L. x Citrus trifoliata L., where this is mentioned in the description.
The use of these hybrids is aimed at correcting the shortcomings of the parent species: trifoliata is sensitive to high pH and drought, while sour orange is extremely susceptible to the citrus tristeza virus. The use of such rootstocks provides a combination of resistance to fungal diseases, including phytophthora, with improved adaptability to soil conditions.
Trifoliata-based hybrid rootstocks often exhibit a growth-restricting effect on the scion, which allows for higher planting density in orchards. An important biological feature is polyembryony, which allows for the production of uniform seed material; however, for successful use, compatibility with the scion variety is critical to eliminate the risk of defects in the graft union zone.
