Plants in A, C, and E represent GT42, and plants in B, D, and F represent GF98-296 (Adopted from Li et al., 2023) 6.2 Case 2: "Yunzhe 05-51", a variety with extremely high sugar content and stress resistance Yunzhe 05-51 is a high-sugar, high-yield and fresh-eating variety bred by the Yunnan Sugarcane Research Institute. This variety was born in 2005 from the hybrid combination YC90-56 × ROC23, and is one of the representative achievements of Yunnan's "double high" sugarcane variety innovation. The "Yunzhe" series represents local breeding varieties in Yunnan. Yunzhe 05-51 plants are tall and strong, with medium and large stems, neat stem nodes, wax powder, dark green leaves, and vigorous growth (Figure 4). Its outstanding features are extremely high sucrose content and strong comprehensive stress resistance. In the trials from 2015 to 2018, the sucrose content of Yunzhe 05-51 remained stable at more than 18% during maturity, reaching a maximum of 18.75%, which was about 1.4 percentage points higher than the control ROC22. Regarding flavor quality, Yunzhe 05-51 has a very high sugar content, and the sweetness is rich and mellow when chewed, but it is "sweet but not greasy", and the taste is well received by consumers (Wu et al., 2024).

From the perspective of production, the promotion of new varieties needs to
