桂糖30是以粤糖91-976为母本,ROC1为父本,采用经过改良的“五圃制”有性杂交选育程序和技术育成的早熟、高糖、高产、多抗、宿根性好、适应性广的甘蔗新品种。2010年5月通过广西省级审定。在广西2年新植1年宿根区域试验的结果表明,平均甘蔗亩产量为6175公斤,比新台糖16号增产6.17%,与新台糖22号相当。平均甘蔗蔗糖分为15.68%,比新台糖16号增0.69个百分点,比新台糖22号增0.72个百分点;11月份平均甘蔗蔗糖分为14.52%,比新台糖16号增0.44个百分点;比新台糖22号增0.73个百分点;2月份平均甘蔗蔗糖分为16.99%,比新台糖16号增1.2个百分点,比新台糖22号增1.29个百分点。平均甘蔗亩含糖量为948公斤,比新台糖16号增糖11.00%,与新台糖22号相当。适宜广西中等以上肥力的土壤种植。
Guitang 30 is made of Yugu sugar 91-976 as female parent and ROC1 as male parent, using the improved “Wupu system” sexual hybrid breeding program and technology to breed precocious, high sugar, high yield, multi-resistance, Good perennial, adaptable sugarcane new varieties. May 2010 passed the provincial-level validation in Guangxi. The results of perennial planting experiments in Guangxi in two years showed that the average yield per mu of sugarcane was 6175 kg, an increase of 6.17% over that of Xintai Sugar 16, equivalent to Xintai Sugar No.22. The average sugar cane sugar is 15.68%, which is 0.69% higher than that of Xintai Sugar16 and 0.72% higher than that of Xintai Sugar No.22. The average sugar cane sugar content in November is 14.52%, 0.44% higher than Xintai Sugar16; Taiwan sugar increased by 0.73 percentage points; in February the average sugar cane sugar was divided into 16.99%, compared with the new Taiwan Sugar 16 by 1.2 percentage points over the new Taiwan Sugar No. 22 by 1.29 percentage points. The average sugarcane sugar content of 948 kilograms, than the new sugar on the 16th sugar 11.00%, with the new Taiwan Sugar No. 22 quite. Suitable for medium-sized fertile soil cultivation in Guangxi.
