引进云南甘蔗新品种(系)比较试验

Comparison Experiment of Introduced Yunnan Sugarcane Varieties

2008年对云蔗03-45等12个引进甘蔗新品种(系)进行新植品比试验。结果表明,综合表现优良的品种是赣蔗95-108、云蔗03-103,其产量为168 350.70、154 784.85 kg/hm^2,分别比对照黔糖4号增产12.49%、3.43%;田间锤度峰值分别为23.35、23.15 Bx,比对照锤度峰值22.55 Bx高0.60 Bx以上;平均锤度依次为21.14、21.21 Bx,均比对照增加0.14 Bx以上,且抗性强、适应性表现突出。表现较好的品种是云农01-58,虽然产量和田间锤度都比黔糖4号低,但抗性突出、适应性较好。

Twelve introduced sugarcane varieties, such as Yunnau sugarcane 03-45, were tested in 2008. The results indicated that Jiangxi sugarcane 95-108 and Yunnan sugarcane 03-103 showed better comprehensive character, their yields were 168 350.70 and 154 784.85 kg/hm^2. Compared with CK （Guizhou sugarcane No. 4） , the yields increased by 12.49% and 3.43% respectively; the peak brixs were 23.35 and 23.15 Bx, which more than 0.60 Bx higher than the CK＇ s peak brix. The average brixs were 21.14 and 21.21 Bx, more than 0.14 Bx higher than the CK＇ s. Besides, they had strong resistance and adaptability. Though the yield and brix of Yunnan 01-58 are lower than Guizhou No. 4, the resistance and adaptability are stronger; therefore, Yunnan 01-58 is a quite good variety.
