广西百色第七轮国家甘蔗品种区域试验

Regional test of the seventh round of national sugarcane varieties in Baise, Guangxi

对入选参加国家第七轮区域试验的9个甘蔗新品种开展综合性区域试验,结果表明,福农04-3504等3个品种蔗茎产量比双对照增产;甘蔗蔗糖分以福农04-2816最高,其次是粤甘24;含糖量最高的是CK1,粤甘26等7个品种2年新植1年宿根蔗含糖量比CK2增产。福农04-3504、粤甘26和粤甘24等3个品种2年新植1年宿根蔗蔗茎产量及含糖量较高,各种农艺性状、经济性状表现较好,在本蔗区有较大的推广潜力,建议扩大试种。闽糖96-1027、C1-2003和福农04-2816个别性状表现优良,但综合性状表现一般或欠差,可作为育种材料给予保护。其他品种表现欠佳,在本蔗区可能难以推广应用。

The comprehensive regional trial of nine country selected new sugarcane varieties were conducted to provide the basis for national variety approval. Cane yield of Funong 04-3504 and other two varieties were higher than the dual- CK; Cane sugar content of Funong 04-2816 showed the highest, followed by Yuegan 24; Sugar content of CK1 showed the highest, sugar content of 2 years＂ new plant and 1 year ratoon Yuegan 26 and other six varieties were higher than CK2. The 2 years＂ new-plant and 1 year ratoon Funong 04- 3504, Yue Gan 26 and Yue Gan 24 had relatively high cane yield and sugar content, agronomic and economic traits were also good and showed potential for popularization in this area that was recommended to expand to grow. Mintang 96-1027, C1-2003 and Funong 04- 2816 showed excellent performance in several characters while ordinary comprehensive characters that should be protected as breeding material.
