摘　　要：‘桂糖56号’(品系名为‘桂糖08-460’)是以‘湛蔗89-113’为母本、‘新台糖26号’为父本按常规五圃制选育出来的甘蔗新品种。广西甘蔗品种区域试验1新2宿的平均结果表明:‘桂糖56号’平均蔗茎产量为99.7 t/hm^(2),对照‘新台糖22号’平均蔗茎产量为87.2 t/hm^(2),比对照‘新台糖22号’增产14.3%。‘桂糖56号’全期平均甘蔗蔗糖分为14.83%,对照‘新台糖22号’全期平均甘蔗蔗糖分为14.47%,比对照‘新台糖22号’高0.36%(绝对值)。‘桂糖56号’平均含糖量为14.3 t/hm^(2),对照‘新台糖22号’平均含糖量为11.7 t/hm^(2),比对照‘新台糖22号’增产22.2%。‘桂糖56号’具有植株高、中大茎、极易脱叶、有效茎数中等、高产、高糖等优良特性,适宜在广西的旱坡地推广种植。Guitang56(clone name:GT 08-460)was developed through“Five-stage selection”,which was derived from the cross of Zhanzhe 89-113דROC”26.The results of plant and first and second ratoon crops from Guangxi sugarcane variety regional test showed that the cane yield of Guitang 56 and the check variety“ROC”22 were 99.7 t/ha and 87.2 t/ha,respectively,and Guitang56 was 14.32%greater than“ROC”22.The sucrose content of Guitang56 and“ROC”22 were 14.65% and 14.29%,respectively,and Guitang56 was 0.36%(absolute value)greater than“ROC”22.The sugar yield of Guitang56 and“ROC”22 were 14.3 t/ha and 11.7 t/ha,respectively,and Guitang56 was 22.16%greater than“ROC”22.Guitang56 with characters of high plant,mid-large stem,easily self-trashing,medium stalk number,high cane and sugar yields,which was suitable to plant in dry land in Guangxi.
