引进国外甘蔗品种比较试验

Comparison Trial between Exotic Sugarcane Varieties

2000～2002年在广西甘蔗研究所大田对引进国外12个甘蔗品种进行新植、宿根各2年的比较试验,结果表明:Q141P44、MEX105、MQ107的综合农艺性状表现较突出,其新植、宿根平均公顷蔗茎产量为83.35、82.48、、81.90、77.77t,比对照种桂糖11号分别增产24.5%、23.2%、22.3%、16.1%;平均蔗糖分分别提高1.33%、1.07%、1.60%、1.57%(绝对值)。

The trial from twelve overseas sugarcane varieties in comparison with their planting and ratoon in the field were conducted in Guangxi Sugarcane Institute in 2000～2002. The results showed that the synthetical agronomical traits both Q141、P44、MEX105 and MQ107 were superior, their mean cane yield of planting and ratoon were 83.35, 82.48, 81.90 and 77.77t per ha and increased by 24.5%, 23.2%, 22.3% and 16.1%, respectively; moreover, the sugar content respectively increased by 1.33%, 1.07%, 1.60% and 1.57% in comparison with the control(Guitang11).
