Evaluation of the 17th Round of New Planting Regional Trials for National New Sugarcane Varieties(lines)in Hechi,Guangxi
摘要
Abstract
[Objective]Carrying out the 17th round of new planting area trials of new sugarcane varieties(lines)at the national level,to provide reference basis for screening out new sugarcane varieties(lines)suitable for promotion and application in the sugarcane areas of Hechi.[Methods]Field trials were conducted with 13 new sugarcane varieties(lines),using'Guiliu 05136'as control 1(CK1)and'Guitang 42'as control 2(CK2).The performance of important agronomic traits were observed and analyzed,including germination rate,tillering rate,plant height,stem diameter,number of stems,yield,sucrose content,fiber content and resistance to diseases and pests.[Results]The results showed that'Zhongzhe 19'and'Zhongzhe 18'had relatively good comprehensive performances.The yield of'Zhongzhe 19'was 79.381 t/hm2,which was 33.47%higher than CK1 and 21.44%higher than CK2.The average sucrose content was 16.32%,which was 0.96 percentage point higher than CK2.The yield of'Zhongzhe 18'was 76.772 t/hm2,which was 29.09%higher than CK1 and 17.45%higher than CK2.The average sucrose content was 15.69%,which was 0.33 percentage point higher than CK2.[Conclusion]Based on the yield,sucrose content and field resistance and other traits of each variety(line)at the Hechi site in Guangxi,'Zhongzhe 19'and'Zhongzhe 18'performed relatively well overall.It is recommended to conduct expansion and observation on these two new varieties(lines).关键词
