According to the information of agricultural planting network, hybridization is to hybridize different varieties of rice. Because different varieties of rice have different genes, their genes are randomly recombined after hybridization, and it is possible to get a better gene combination, so it is not obtained by transgenic technology.

Transgenic rice includes: BT63 transgenic insect-resistant rice, Huahui 1, BT Shanyou 63, etc. Transgene refers to the transfer of a specific foreign target gene into the recipient organism through DNA recombination and transformation, and makes it produce predictable and directional genetic changes.
