The invention discloses a sugarcane selection breeding informatization tag and belongs to the technical field of sugarcane conventional hybridization selection breeding. The tag comprises a rectangular body, semi-round gaps symmetrically formed in the positions, close to one end, of two long sides of the body and close to one end and corresponding to each other, a round hole and a rectangular hole formed in the positions, close to the other end, of the body, used for fastening the two semi-round gaps and connected with each other, and a two-dimensional code sticker located between the two semi-round gaps and the rectangular hole, wherein the round hole is located in one side far away from the two-dimensional code sticker; and the rectangular hole is located in one side close to the two-dimensional code sticker. The tag is used in field breeding work of sugarcane conventional hybridization, so that scientific research personnel can easily read and identify target trait sugarcane when selecting the target trait sugarcane in massive sugarcane single plants or groups, and the identification ability and data processing ability of the scientific research personnel for the target trait sugarcane of the single plants or the groups in the sugarcane conventional selection breeding are greatly improved.
