Difference between Intergeneric vs interspecific (Horticulture point of view)?
Answers
Interspecific and intergeneric hybridization is an important research approach creating usable variability for breeding. Desirable traits like resistance against pathogens or abiotic stress within varying environments, composition of metabolites or morphological traits and their responsible genes are often found only within wild species, related species and genera of the cultivars.
It is possible to use the existing variability of the primary and secondary gene pool by interspecific and intergeneric hybridization. Thereby, an important precondition and basis for the coverage of the further breeding progress is accomplished.
Interspecific and intergeneric hybridization can be carried out both-way, generatively by crossing or somatically by protoplast fusion. The Institute for Breeding Research on Horticultural Crops has acquired wide experience in the development and adaption of the generative as well as somatic hybridization of vegetables, ornamentals and medical and aromatic plants for many years. Both methods are very labor-intensive, long-lasting and fraught with risk. Therefore, the breeding lines are chosen very carefully and are proved for defined valuable traits in advance.
