广西糖料蔗品种登记状况分析

Analysis on the Status of Sugarcane Variety Registration in Guangxi

为推动“双高”糖业发展,统计非主要农作物品种登记制度实施以来广西糖料蔗品种登记情况,对2018—2023年通过登记的41个广西糖料蔗品种产量、含糖量等登记信息统计分析。区内育种单位单独登记品种比例为80.49%,2018—2020年为广西糖料蔗品种登记高峰年份,之后显著减少;产量高于对照的品种,占比为58.54%,其中显著高于对照的品种有7个,显著低于对照的品种有3个(P>0.05),仅有65.85%的品种含糖量高于对照,且所有品种的含糖量均未显著高于或低于对照品种。“桂糖44号”“桂糖52号”“柳糖2号”“桂柳07150”“中蔗10号”5个品种含糖量、产量均优于对照品种,应大力推广,其他品种要注重在各生态区开展品种筛选、推广工作,充分挖掘品种潜力。

In order to promote the development of the“double high”sugar industry,the status of sugarcane variety registration in Guangxi since the implementation of the non-major crop variety registration system was analyzed.The yield and sugar content of 41 sugarcane varieties registered in Guangxi from 2018 to 2023 were statistically analyzed.The proportion of varieties registered by breeding units was 80.49%,which significantly decreased after the peak year of sugarcane variety registration in Guangxi from 2018 to 2020.The yield of cultivars was higher than the control,accounting for 58.54%,of which 7 cultivars were significantly higher than the control,and 3 cultivars were significantly lower than the control(P>0.05).Only 65.85%of the cultivars had higher sugar content than the control,and the sugar content of all cultivars was not significantly higher or lower than the control.The six varieties of“Guitang 44”“Liutang 2”,and“Zhongcane 10”were superior to the control species in sugar content and yield and should be vigorously promoted.The other varieties should pay attention to variety screening and promotion in various ecological areas to fully tap the potential of the varieties.
