The objective of the paper was to introduce the breeding process of a new sugarcane cultivar, Yuetang 06-233, and its agronomic characters, stem yield, sucrose content, and disease and abiotic stress resistance. Yuetang 06-233, with early-maturing type, high stem yield, high sucrose content and good adversity resistance was successfully bred using Yuetang 94-128 and Yuetang 93-159 as female and male parents, after 8 generations selection based on agronomic, sugar, and yield traits. It exhibited high sugar yield and maximum stem yield at 18 145.79 kg/hm 2 and 119 932.56 kg/hm 2 in the national regional and production test, respectively, and it was highly resistant to Smut. Meanwhile, the chromosome number and karyotype of Yuetang 06-233 was studied by shedding cell wall and dialysis methods. The results showed that the chromosomes of the cultivar mainly was metacentric or submetacentric. The chromosome number of Yuetang 06-233 was 88, the karyotype formula was K(2n)=88=82m+6sm.

Key words: sugarcane, Yuetang 06-233, breeding, karyotyping
