不同甘蔗品种(系)的产量构成因素及品质比较

Comparison Study on the Yield Components and Quality of Different Sugarcane Varieties(Lines)

以新台糖22号为对照(CK),对参试的9个甘蔗品种(系)进行田间一年新植和一年宿根的品比试验,调查参试品种(系)的农艺性状、抗逆性状及产量构成性状,对其进行综合评价。结果表明,9个参试品种(系)比CK增产增糖的品种(系)有6个,其中桂热2号和凉蔗02-186的分蘖率、宿根发株率、蔗茎产量、含糖量和有效茎数等较CK有明显的优势,福农41号的枯心苗率和梢腐病率最高,凉蔗07-53、凉蔗03-23和凉蔗03-81蔗糖分偏低,其他材料与CK差异不大。通过产量和总含糖量综合分析,桂热2号、凉蔗02-186、桂糖42号表现优异,适宜在广西南宁地区及气候相似蔗区大面积推广应用。

In this experiment,ROC22 was used as the control(CK),and nine sugarcane varieties(lines) were tested in the field for plant cane and first ratoon.The agronomic traits,stress resistance and yield traits were investigated and comprehensively evaluated.The results showed that there were six varieties(lines) that increased yield and increased sugar content compared with CK.Among them,the indexes of rate of tillering,rate of perennial root sprout,sugarcane yield,sugar content and effective productive stalk had obvious advantages with CK on Guire 2 and Liangzhe 02-186.The Dead heart rate and tip rot rate of Funong 41 was the highest.The sucrose contents of Liangzhe 07-53,Liangzhe03-23 and Liangzhe 03-81 were lower,and there was not much difference among other sugarcane varieties(lines).Guire 2,Liangzhe 02-186,and Guitang 42 had excellent performance in yield and total sugar content therefore they are suitable for large-scale demonstration and promotion in Nanning,Guangxi or climate similar sugarcane area.
