Abstract:
Objective A new sugarcane variety of high yield, high sucrose content, strong ratooning ability, and superb stress resistance was bred.
Method A sexual hybridization breeding program, "Five-nursery System", was applied using Yuenong 73-204 as the female parent and CP72-1210 as the male parent for the breeding. Morphology and production of the new sugarcane variety were evaluated at official trials.
Results The Mintang 11610 plant had a medium to large stem and superb performances on seedling emergence, tillering ability, stalk formation, lodging resistance, and ratooning ability. In the 2015–2020 trials, it showed a convincing 13.89% higher average cane yield of 152.998 t·hm−2, 1.44% higher sucrose content (in absolute value) of 16.31%, 24.90% higher crop sugar yield of 24.946 t·hm−2, 28.23% higher perennial root cultivated cane yield of 166.268 t·hm−2, 1.07% higher sucrose content (in absolute value) of 16.79%, and 36.99% higher sugar yield of 27.919 t·hm−2 than those of control. It was officially approved a national non-major crop variety in December 2023 with the registration number of “GPD Sugarcane (2023) 350009”.
Conclusion Mintang 11610 was an officially certified early-maturing, high-yield, high-sucrose, premium ratooning sugarcane with broad adaptability and stable yield.
