hybridization consists of crossing genetically different parents to generate more fragrant or resistant plants. Human intervention has consisted of improving hybrids so that the plants are more floriferous, productive or efficient.
Crossing also takes place between species, as with caseille (crossing blackcurrant and Ribes gooseberry ) or pluot. Even more technical are the crossings between genres: mangave is a mix between manfreda and agave. To hybridize a flower, first opt for so-called “fixed” varieties, plants whose hybridization is stable.
