福建省甘蔗新品种区域试验研究

通过2001～2002年2年(2新1宿)6个地点的区域试验，参试的甘蔗新品种中闽糖86—2121。粤农91—854表现出高产。稳产、适应性较广的特点，蔗茎产量比闽糖70—611增少达极显著水平，与闽糖86—05增少(或减少)不显著，含糖量比闽糖70—611增少21．82％和12．86％，比闽糖86—05增少0．41％和减少6．98％，适宜于福建蔗区示范推广。闽糖93—246蔗茎产量比闽糖70—611增少不显著，比闽糖86—05减少达显著水平，适应性一般，宿根性较差，含糖量比闽糖70—611增少9．86％，比闽糖86—05减少9．46％，可保留区试。粤C25、福农93—3608蔗茎产量比闽糖70—611减少达不显著和显著水平，比闽糖86—05减少达极显著水平、适应性广，稳产性一般，含糖量比2个对照种都有不同程度的减少，不适宜在福建蔗区示范推广。

Studies on Regional Trial of Sugarcane Varieties in Fujian Province

The regional trial of sugarcane varieties had been taken place on six spots in Fuj ian Province from 2001 -2002. The results showed: compared with Mintang 70-611(CK1) and Mingtang 86-05(CK2), Mintang 86-2121, Yuenong 91-854 had good performance in cane yield, stability and adaptability, their cane yield increases reached extremely significant level than CK1, but below the significant level than CK2, sugar content increase 21.82% and 12.86% than CK1, increase 0.41% and decrease 6.98% than CK2, they can been demonstrated and expanded further in Fujian Province; Mingtang 93-246 increase below the significant level than CK1, but decrease reached extremely significant than CK2 in cane yield, sugar content increase 9.86% than CK1, decrease 9.46% than CK2, it can been further tested in the regional trial; YueC25, Funong 93-3608 had wild adaptability, but stability were common, their cane yields decrease below (or reached) the significant level than CK1, but reached extremely significant level than CK2, sugar content decrease different degree than the two check varieties, they shouldn't been demonstrated and expanded further in Fujian Province.
