几个桂糖新品种宿根蔗生长及产量和蔗糖分的表现

摘要

Variety comparison tests were conducted for Guitang29, Guitang30, Guitang31, Guitang32 and Guitang34 using ROC22 as the check variety, to study their features in ratooning crop. The results showed that the cane yield and sugar yield of all Guitang varieties were higher that that of the check. 3 Guitang varieties performed better in sugar content than the check and the other 2 were worse. It is indicated that the tested Guitang varieties were all better than the check variety ROC22 in overall ratooning performance.%以ROC22作对照，对桂糖29号、桂糖30号、桂糖31号、桂糖32号、桂糖34号等5个新品种进行宿根蔗品种比较试验，探讨不同品种宿根性及生长特性。结果表明，所有桂糖新品种宿根蔗茎产量均高于对照种；平均甘蔗蔗糖分有桂糖29号、桂糖30号、桂糖34号3个品种高于对照，桂糖31号、桂糖32号2个品种不如对照；桂糖品种单位面积含糖量均高于对照种。综合各品种的宿根表现，认为参试的5个桂糖新品种其宿根性均优于对照种ROC22。
