果蔗良种品比试验初报

为解决贵州无糖厂蔗区果蔗良种供应问题，促进果蔗产业发展，助农增收，2008年贵州省亚热带作物研究所从浙江省义乌市引进果蔗良种进行品比试验，以期择优示范推广。方法：采取随机区组设计，3个区组，3次重复，定期观察，年底测产。结果表明：宁化果蔗品质优良，平均田间糖分锤度18.60%较对照(罗汉蔗)高3.47个百分点]、平均单产6 854.49 kg/667m2(较对照增产2 701.39 kg/667 m2)，增产率65.05%；福建1号品质优良，平均田间糖分锤度16.60%(较对照高1.47个百分点)、平均单产6789.27 kg/667 m2(较对照增产2636.17 kg/667 m2)、增产率63.47%；四川白鳝蔗品质优良，平均田间糖分锤度18.10%(较对照高2.97个百分点)、平均单产7 380.39 kg/667 m2(较对照增产 3 227.29 kg/667 m2)，增产率77.71%；广东黄皮果蔗品质优良，平均田间糖分锤度18.65%(较对照高3.52个百分点)，平均单产7 709.32 kg/667 m2(较对照增产3 556.22 kg/667 m2)，增产率85.63%。同时，宁化果蔗、福建1号、四川白鳝蔗及广东黄皮果蔗还表现出较强的抗病性、抗虫性、抗寒性及抗旱性。

Preliminary Comparison Study of Chewing Cane Cultivars

To solve the problem of provide with perfect chewing cane cultivars in the area of no sugar-refinery, help develop chewing cane industry and enhance income for farmer, chewing cane variety comparison test was conduct with varieties which come from Yiwu city Zhejiang province in 2008. All the sugarcane variety were randomly divided into 3groups, 3 repeat. According to the result of experiment of 2010 planting and 2010 stubble cane. The main agronomic character of Ninghua chewing cane was better, the average XB of stalks and cane average yield increased 3.47% and 2 701.39 kg/667 m2 respectively than check variety (Luohan); For Fujiang 1 chewing cane, the average XB of stalks and cane average yield increased 1.47% and 2 636.17 kg/667 m2 respectively than check variety (Luohan); For Sichuan Baishan chewing cane, the average XB of stalks and cane average yield increased 2.97% and 3 227.29 kg/667 m2 respectively than check variety (Luohan); For Guangdong Huangpi chewing cane, the average XB of stalks and cane average yield increased 3.52% and 3 556.22 kg/667 m2 respectively than check variety (Luohan). At the same time, Ninghua, Fujian 1, Sichuan Baishan and Guangdong Huangpi also showed strong disease resistance, insect resistance, cold resistance and drought resistance.
