Method A sexual hybridization breeding program was carried out using Yuenong 73-204 as the female parent and CP72-1210 as the male parent. the new variety Mintang 11610 was bred systematically through sexual hybridizatior and "Five-nursery System" breeding procedure. Then morphological characteristics and production characteristics were evaluated synthetically in the regional trial and production trial. Results The plants of Mintang 11610 were erect, medium to large stem; good seedling emergence, strong tillering ability, and a high stalk formation rate. It demonstrated strong lodging resistance and excellent ratooning ability.From 2015 to 2020, the average cane yield was 154.261 t·hm−2, which was increased by 15.11% compared with those of CK. The sucrose content was 16.30%, which was 1.43% higher than that of CK (absolute value).The yields of sugar was 25.145 t·hm−2, which increased by 26.18% compared with those of CK. During Perennial root cultivation, the yields of cane was 168.574 t·hm−2, which increased by 31.40% compared with those of CK, the sucrose content was 16.79%, which increased by 1.07% compared with that of CK (absolute value), the yields of sugar was 28.304 t· hm−2, which increased by 40.34%. Mintang 11610 was officially registered as a national non-major crop variety in December 2023, with the registration number GPD Sugarcane (2023) 350009. Conclusion Mintang 11610 is characterized by early maturity, high yield, high sugar content, good ratoonine abilities, The stability analysis showed that the stable high yield of this variety was better than that of CK, and the adaptability was wide. -
