摘要
通过本试验可知,参试的4个品种中,新植蔗时,桂糖29、桂糖32和桂糖40在螟虫危害和黑穗危害方面均弱于对照,但组培新台糖22与对照相差不大;但宿根时,3个品种的表现均居于前,且甘蔗产量和甘蔗品质与对照相比,均有不同程度的增加,虽桂糖40在病虫害方面表现优于桂糖29和桂糖32,但从产量、甘蔗纤维分、甘蔗糖分增加程度而言,均低于上述两个品种,综上所知,建议优先推广桂糖29和桂糖32。
according to the experiment,when new plant period,the testing four varieties,as Guitang 29 （GT29）,guitang32 （GT32）and Guitang 40 （GT40）performed a little worse than seedcane ROC22 in borer damage and smut infection aspects, and tissue ROC22 performed close with seedcane ROC22 in borer and smut resistance;when ratoon period, those three vari- eties performed much better than seedcane ROC22,espeeially,both yield and quality were much higher;although GT 40 performed much better in borer damage and smut infection aspects, and yield, fiber in cane, sucrose and C.C.S were increas- ing less than GT29 and GT 32,finally,we suggest to multiply GT29 and GT 32 first.
