40 newly developed domestic sugarcane varieties (lines) were used to screen sugarcane varieties with strong cold tolerance and excellent comprehensive traits in Quanzhou county, Guangxi. The results indicated that the value of plant height, stem diameter, millable stalk number, single stalk weight and cane yield of plant crop were higher than those in ratoon crop under natural low temperature conditions, with extremely significant difference observed in plant height, single stalk weight, and cane yield between plant crop and ratoon crop. There were significant or highly significant difference in plant height, stem diameter, millable stalk number, single stalk weight and cane yield among different varieties. Field brix, sucrose content and purity of plant crop and ratoon crop exhibited an ascending trend before the arrival of the first strong low-temperature weather, afterwards exhibited an declining trend. Stalk length damage rate (SDR) demonstrated a progressive increase across three survey periods in both plant crop and ratoon crop, but green leaves percentage (GLP) was gradually decreasing. Plant damage rate (PDR) differed among varieties initially, while in the second and third investigation, PDR reached 100% for all varieties. GT51, GT32, GT13-532, DZ09-78, GT58 and GT52 exhibited strong cold tolerance based on the the subordinate function method. The result from maximum entropy-minimum residual composite index model demonstrated that sugar content, cane yield and millble cane number in ratoon crop ranked the top three in weight coefficients, exerting significant impacts on the comprehensive evaluation of sugarcane varieties. DZ07-36, ZT1, ZZ6, YT07-913, FN38, DZ09-78, GT55, GT51, GT52, GT42 and GT58 showed overall superior performance and are suitable for promotion in colder northern sugarcane-growing regions.
