为培育高产、高糖、多抗的甘蔗新品种,不断满足糖料生产发展的需要,2000～2008年,采用“五圃制”的常规杂交育种的技术路线进行选择与培育,育成了特高糖高产抗旱抗寒的甘蔗新品种桂糖28。桂糖28(原名桂糖00-122),其亲系为CP80-1018×CP88-2032。该品种中至中大茎,特早熟、特高糖、高产、宿根性好,抗逆性强,适应性广,极易脱叶。甘蔗蔗糖分(16.60%)较ROC16(15.07%)高1.53%,最高甘蔗蔗糖分达19.19%;产蔗量(86.2 t/hm2)较ROC16(83.1 t/hm2)增产3.73%,最高产蔗量达159.2 t/hm2;含糖量(14.31 t/hm2)较ROC16(12.52 t/hm2)增产14.30%。适应于广西、云南、广东、福建等省蔗区种植。桂糖28的育成是广西甘蔗高糖育种取得的突破性进展,对丰富我国甘蔗品种材料,改良目前甘蔗单一化的品种结构具有重要现实意义。
In order to cultivate new varieties of sugarcane with high yield, high sugar and multi-resistance, we continuously met the need of the development of sugar production. From 2000 to 2008, we selected and cultivated the conventional hybrid breeding technology of “Wu Pu system” Super sugar high yield, high yield, drought resistant and cold resistant new sugar cane 28. Gui sugar 28 (formerly called Gui sugar 00-122), the progeny CP80-1018 × CP88-2032. The species to the large stem, especially precocious, extra-high sugar, high yield, good perennial, strong resistance, wide adaptability, easy to defoliate. The sugar content of cane (16.60%) was 1.53% higher than that of ROC16 (15.07%) and the highest cane sugar content was 19.19%. The yield of sugarcane (86.2 t / hm2) was 3.73% higher than that of ROC16 Reaching 159.2 t / hm2. The sugar content (14.31 t / hm2) increased by 14.30% compared with that of ROC16 (12.52 t / hm2). Adapted to Guangxi, Yunnan, Guangdong, Fujian and other provinces planted sugar cane. The breeding of Guitang 28 is a breakthrough made in sugar cane breeding in Guangxi, which is of great practical significance to enrich our country’s sugarcane variety materials and improve the current single species structure of sugarcane.
