利用高稳系数分析法(HSC法)对桂糖31号的丰产性及稳产性进行分析,结果表明,桂糖31号平均蔗茎产量、含糖量比新台糖22号和新台糖16号高,产量、含糖量的高稳系数也比新台糖22号和新台糖16号高,而产量、含糖量的变异系数比新台糖22号和新台糖16号小,尤其在宿根试验中产量、含糖量表现更为突出;甘蔗蔗糖分在11月份与新台糖22号相当,12月份以后达到和超过新台糖22号的水平。说明桂糖31号是一个丰产、稳产、宿根性好、适应性广、中熟、高糖的甘蔗优良品种,适宜推广应用。
The results showed that the average cane yield and sugar content of Guitang No.31 were higher than those of Xintai No.22 and No.16 Taihangsui by the method of high stability coefficient analysis (HSC) , The high stable coefficient of yield and sugar content was also higher than that of Xintai No.22 and Xintai No.16, and the coefficient of variation of yield and sugar content was smaller than those of Xintai No.222 and Xintai No.16, especially in the pest experiment , Sugar content is more prominent; sugarcane cane sugar points in November with the new Taiwan Sugar No. 22, after December reached or exceeded the new Taiwan Sugar 22 level. Gui sugar No. 31 is a high yield, stable yield, good rooting, adaptability, medium maturity, high sugar sugarcane varieties, suitable for promotion and application.
