Breeding of strawberries variety "Old Black", which is of uncertain origin. This variety was created by pollination, not direct manipulation of the plant's genes. Molecular breeding is the application of molecular biology tools in a breeding program. Genetic engineering is typically defined as the introduction of non-native genes into an organism. An excellent example of transgenic modification is in the case of cold resistant strawberries.
