采用高稳系数法和变异系数法分析了甘蔗新品种桂糖46号在2年区域试验中的丰产稳产性。结果表明:相比ROC22号,桂糖46号具有非常优良的丰产性,蔗茎产量和含糖量的增产(糖)非常明显,蔗糖分略高;在此基础上,桂糖46号还具有优良的稳定性,蔗茎产量和含糖量的高稳系数均高出对照30%以上,蔗糖分的高稳系数也略高,分析结果用变异系数法也得到了验证。综合来看,桂糖46号是一个高产、稳产、宿根性好、适应性广、抗倒性强、脱叶性好的优良甘蔗新品种,具有很好的推广前景。
High-yield coefficient method and coefficient-of-variation method were used to analyze the high-yield stability of the new sugarcane variety Guiguang 46 in the two-year regional experiment. The results showed that compared with ROC22, Guiguang No.46 had very high yield, the output of sugarcane and yield (sugar) of sugarcane were very obvious and the content of sucrose was slightly higher. On the basis of this, Guiguang 46 also had Excellent stability, high yield stability of cane stems and high sugar content were both higher than 30% of the control, and the high stability coefficients of sucrose were also slightly higher. The analysis results were also verified by the coefficient of variation method. Taken together, Guiguang 46 is a good new sugarcane variety with high yield, stable yield, good rooting ability, wide adaptability, strong lodging resistance and good defoliation, which has good promotion prospects.
