Variety traits
Hybrids between Citrus x aurantium L. x Citrus trifoliata L.
The origin of hybrids between sour orange and trifoliate orange is a qualitative genetic characteristic, confirmed by molecular analysis and parental pair registration.
In the reference 3 varieties crop Hybrids between Citrus x aurantium L. x Citrus trifoliata L., where this is mentioned in the description.
For hybrids of Citrus x aurantium L. and Citrus trifoliata L., the origin is defined as a pedigree established through the documentation of crosses in breeding logs or germplasm databases. The trait has no quantitative expression, and its confirmation is based on the analysis of nuclear and chloroplast genomes.
The genetic origin of these hybrids directly determines their value as rootstocks. The use of Citrus trifoliata in parental lines provides the progeny with increased cold hardiness, specific adaptation to soil conditions, and resistance to Citrus tristeza virus.
