摘　　要：对国内6个省区12个参试抗旱品种(系)2年新植丰产性试验资料进行分析比较。结果表明:桂糖89/5的出苗率高,有效茎多,蔗产量和含糖量高且稳定性好,1/15hm2蔗产量和含糖量分别比对照品种川蔗17号高1.383和0.134t,分别增加24%和15%;川糖89/103和川糖91/91两品种(系)的蔗产量和含糖量表现突出,1/15hm2蔗产量分别为7.919和6.960t,分别比川蔗17号高37%和20%,含糖量分别比川蔗17号高21%和27%。这3个品种(系)可作为四川盆地丘陵旱坡地地区只种新植蔗不种宿根蔗农户的重要选择品种。Through analysis and comparison of the experimental data of abundant productivity of two years on 12 experimental sugarcane droughtresistant varieties/lines from 6 provinces/autonomous regions of China, it was showed that GT89/5 had a high germinating power, high millable stalk number, and high stable cane and sugar yield. The cane yield and sugar content per unit area of GT89/5 were 20.745 t/ha and 2.010 t/ha higher than those of check variety CZ17 respectively, which increased by 24% and 15% respectively. The cane yield and sugar content per unit area of CT89/103 and CT91/91 were prominent. The cane yield of CT89/103 and CT91/91 were 118.785 t/ha and 104.400 t/ha respectively, which increasedly 37% and 20% respectively. The sugar content of CT89/103 and CT91/91 were 21% and 27% higher than that of CZ17. These three varieties/lines were important for the farmers to select varieties as plant cane on hillside lands of Sichuan Basin.
