2012—2013年广西甘蔗品种区域试验初报

Preliminary report on regional trial for sugarcane varieties of Guangxi in 2012-2013

为筛选适合在广西生态气候区种植的优良甘蔗新品种,以新台糖22号作对照,对13个甘蔗新品系在南宁、柳州、河池、百色、北海、崇左等6个试点进行品种比较试验,并分析了各参试品系的蔗茎产量、蔗糖分和公顷含糖量。结果表明:在新植试验中,柳糖07-95、桂糖05-818、桂糖04-1045等3个新品系综合表现较好,其产量及蔗糖分均显著高于对照;其次是桂糖03-591、桂糖06-533、桂糖04-2603,其蔗茎产量及公顷含糖量均高于对照;桂糖03-66、桂糖03-91、桂糖04-1545的蔗糖分均高于对照,其余品系表现一般。

In order to evalute the performance of new sugurcane clones for adaptability of plant in different ecological climate zone in Guangxi, 13 excellent new sugarcane varieties were selected to compare with the variety ROC 22. The experiments with the sugarcane clones were carried out in Nanning, Liuzhou, Hechi, Baise, Beihai and Chongzuo respetively, and the yield, sugar and hectare sucrose content were analysed. The results showed that Liutang 07-95, GT 05-818, GT 04-1045 had the best performance, surpassed ROC22 in production and sucrose content, GT 03-591, GT 06- 533, GT 04-2603 had the better performance their yield and sugar content surpassed ROC22, the sucrose contents of GT 03-66, GT 03-91 and GT 04-1545 were better than that of ROC22, and the rest varieties had general performance in this planting experiment.
