Traditional breedingTraditional breeding methods entail the careful selectionSelection of individual plants possessing sought-after characteristics, followed by crossbreeding to yieldYield offspring inheriting a blend of those traits.

In recent years, molecular breedingMolecular breeding techniques have been developed that allow breeders to manipulate the DNA of orchidsOrchids more precisely. For example, genome editingGenome editing tools such as CRISPR/Cas9 can insert or delete specific genesGene, resulting in plants with desirable traits such as disease resistanceDisease resistance or altered flowerFlower morphologyMorphology.
