摘　　要：为了筛选适应广西蔗区地理环境、稳产高糖的甘蔗品种,实现品种多样化,提高应对病虫害、气候环境变化等不利因素的能力,在前期引进栽培试验的基础上,将筛选出的3个甘蔗品种(系)进行适应性和农艺性状的观测分析。通过一年新植一年宿根的比较试验,发现凉蔗02-6、凉蔗03-81的农艺性状与当前主栽品种新台糖22号(CK)综合比较具有一定的优势。其中凉蔗02-6的分蘖率、株高、茎径、有效茎、甘蔗产量等性状都优于CK,蔗糖分与CK相当,新植、宿根凉蔗02-6产糖量分别比CK高约2.08t/hm2、2.86t/hm2且差异显著;凉蔗03-81甘蔗产量和产糖量等性状显著优于CK,但是蔗糖分显著低于CK,制糖成本较高,影响制糖企业效益。此外,对不同甘蔗品种(系)生长的跟踪观测发现,凉蔗02-6具有较强的抗旱抗寒能力。In this study,four different sugarcane varieties（lines） were used to experimentally compare their adaptability and agronomic traits. The results showed that agronomic traits of Liangzhe 02-6 and Liangzhe 03-81 were better than those of Xintaitang 22（CK）,including higher tillering rate,plant height,stem diameter and stalk and yield in Liangzhe 02-6. Although sucrose content was lower,Liangzhe 02-6 had more sugar yield per hectare than those in CK,about 2.08t/hm^2 and 2.86t/hm^2,respectively. For the Liangzhe 03-81,sucrose concent was significantly lower than that of CK. In addition,Liangzhe 02-6 had strong drought and cold tolerance.
