Yuetang1396 is a new sugarcane variety bred by crossing HoCP02-623,which is high-yielding,high-sugar,and has good ratooning characteristics,with Xintaitang22,which is high-yielding,high-sugar,and has good adaptability.It was participated the 15th national regional regional trial of sugarcane during 2021 to 2023 and was evaluated at 8 experimental points including Suixi in Guangdong,Chongzuo,Guilin,Hechi,Liucheng,Longzhou Xingbin in Guangxi,and Lingao in Hainan.The results showed that it had an average cane stem yield of 90.71 t/hm2 for one-year new planting and two years of ratooning,which was 9.52%higher than the control Guiliu05136;the average sugar content was 13.09 t/hm2,which was 3.21%higher than the control.The average sucrose content of sugarcane from November to March of the following year was 14.55%,which was 0.92 percentage points(absolute value)lower than the control Guiliu05136.Among the eight experimental sites,Yuetang1396 showed differences in yield,sugar content,and sucrose content,and it showed significant yield and sugar increase in Guilin,Hechi,Longzhou,and Linggao,which was especially suitable for the planting of Yuetang1396.Yuetang1396 is a high-yielding and late-maturing variety with excellent characteristics such as tall plant,medium to large stem,high tillering rate,many effective stems,uniform population,high ratoon rate,good ratoon characteristics,moderate resistance to black rot,and good drought resistance.It has high potential for promotion and is suitable for planting on dry slopes and water-drought fields with medium or above soil fertility.This variety was registered by the state in October 2021,and the registration number is GPD Sugarcane(2021)440021.
