【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。更多还原

【Abstract】 Guitang56(clone name: GT 08-460) was developed through“Five-stage selection”, which was derived from the cross of Zhanzhe 89-113 דROC”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.更多还原
