【摘要】 【目的】评价新选育甘蔗品种(系)在开远点的丰产性、糖分和稳定性，为甘蔗优良品种推广应用提供参考。【方法】共12份参试材料，‘新台糖22号’为对照，2019—2021年进行1年新植、2年宿根田间试验，并对农艺性状、工艺性状、蔗茎产量和蔗糖产量等进行综合评价分析。【结果】在开远试点，综合评价表现最佳的为‘云蔗121185’、‘云蔗121220’、‘云蔗113898’,与对照相比，蔗茎产量分别增加20.19%、5.92%、3.56%,蔗糖产量分别提高27.13%、14.59%、5.05%;蔗糖分表现最佳的为‘云蔗13165’、‘云蔗103148’,平均蔗糖分分别为16.7%、16.26%,蔗糖产量较对照分别提高了7.43%、6.95%。【结论】在开远试点综合性状较优的品种(系)为‘云蔗121185’、‘云蔗121220’和‘云蔗113898’,可以考虑进一步在开远及临近区域推广种植。更多还原

【Abstract】 【Objective】 To evaluate high yield, sugar content, and stability of new sugarcane clones and their promotion value. 【Method】 A total of 12 varieties were tested, and ‘XTT22’ was used as the control. The field experiment was conducted from 2019 to 2022, including a plant crop and two ratoons. Comprehensive evaluation analysis was performed on the agronomic traits, processing traits, cane yield, sucrose yield, and etc. 【Result】 In Kaiyuan regional test site, ‘YZ121185’, ‘YZ121220’ and ‘YZ113898’ showed the best performance. As compared with CK, the cane yield increased by 20.19%, 5.92% and 3.56%, respectively; and the sucrose yield increased by 27.13%, 14.59% and 5.05%. The varieties with the highest sugar content were ‘YZ13165’ and ‘YZ103148’, with average sucrose contents of 16.7% and 16.26%, respectively, and the sucrose yields surpassed CK by 7.43% and 6.95%. 【Conclusion】 The clones with superior comprehensive traits in Kaiyuan were ‘YZ121185’, ‘YZ121220’ and ‘YZ113898’, which could be further promoted and planted in Kaiyuan and similar regions.更多还原
