粤糖系列主栽及主推品种生产性能试验初报

摘要

A production performance trial with five leading cultivated and popularized varieties of Yuetang 60(YT60), Yueyin 09-618(YY09-618), Yuetang 55(YT55), Yuetang 00-236(YT00-236), Yuetang 86-368(YT86- 368) and the ROC22(the check) was conducted in Zhanjiang Sugarcane Research Center in 2011. Result showed that both the cane yield and sugar yield of YT55 were the highest among the six varieties, with 1.35 and 1.22 times as high as ROC22, respectively, followed by YT60. The stalk diameter of YT60 was 0.4 cm more than that of ROC22. The single stalk weight was 0.6 kg heavier than that of ROC22. YY 09-618 performed best in terms of tillering capacity, which was about 100% increasing compared to ROC22. YT 00-236 was the earliest maturing variety with 0.55% of sucrose content (absolute value) higher than the check. However more information on the ratooning ability, stress resistance and the adaptation to different soils of the varieties should be observed in subsequent experiments.%以ROC22作对照，对粤糖60号、粤引09—618、粤糖55号、粤糖00—236和粤糖86．3685个粤糖主栽及主推品种进行新植1年生产性能试验。结果表明：粤糖55号的公顷蔗茎产量和含糖量最高，分别是ROC22的1．35倍和1．22倍，其次是粤糖60号；粤糖60号的茎径、单茎重分别比ROC22增粗0．40cm和增重0．6kg／茎；粤引09—618分蘖能力最强，约为ROC22的2倍；粤糖00—236表现最早熟，11月份甘蔗蔗糖分比ROC22提高0．55％（绝对值）。关于品种的宿根性、抗逆性以及在不同土壤上的适应性等，尚需后续试验进一步观察确定。
