桂糖29号(原编号桂糖02-761)是广西甘蔗研究所从崖城94-46×新台糖22号杂交组合后代中选育的最新甘蔗优良品种。该品种表现为萌芽好,分蘖力强,植株较直立紧凑,中茎,有效茎数多,早熟高糖,丰产,宿根性特强。广西区试试验结果,平均蔗茎产量95.7t/hm2,比CK2(ROC16)增产12.1%,与CK1(ROC22)相近,其中,宿根蔗产蔗量94.0t/hm2,比CK1和CK2增产10.5%和19.4%;平均蔗糖分15.62%,比CK1和CK2高0.60和0.64个百分点;平均含糖量15.0t/hm2,比CK1和CK2增产4.2%和17.2%。该品种适应性广,抗寒性明显优于ROC22。该品种于2010年5月通过广西农作物品种审定委员会审定正式命名为桂糖29号。
Gui Sugar No.29 (original code Gui Zhi 02-761) is the latest sugarcane variety of Guangxi Sugarcane Research Institute, which was selected from the offspring of 94 combinations of Yacheng 94-46 × Xintai 22 hybrids. The varieties showed good germination, tillering ability, plant more upright compact, medium stems, effective stems and more, early high-sugar, high yield, perennial exceptionally strong. In Guangxi area, the average cane yield was 95.7t / hm2, which was 12.1% higher than CK2 (ROC16) and similar to CK1 (ROC22), in which the yield of sugarcane was 94.0t / hm2, 10.5% more than that of CK1 and CK2 And 19.4% respectively. The average sucrose content was 15.62%, which was 0.60 and 0.64 percentage points higher than that of CK1 and CK2. The average sugar content was 15.0t / hm2, 4.2% and 17.2% higher than that of CK1 and CK2. The variety of wide adaptability, cold resistance was significantly better than the ROC22. The variety in May 2010 through the Guangxi Crop Variety Approval Committee officially named Gui sugar on the 29th.
