2003～2004年广西甘蔗品种区域试验报告

为探讨我区新育成及引进的甘蔗优良品系在全区各蔗区的表现,为新品种的选育、审定和推广提供依据,自2003年1月至2005年1月,实施了由9个区试点参加、涉及8个参试材料及一个对照品种的广西甘蔗品种区域试验。结果表明:桂糖96-154,中大茎,早熟、高糖、丰产,宿根性、抗旱能力强,甘蔗蔗糖分与新台糖16号相近,产蔗量较新台糖16号增12.4%,含糖量增10.2%;桂糖96-211,中大茎、早熟、丰产、高糖,宿根性强,产蔗量较对照增121%,含糖量增10.2%,蔗糖分与对照种新台糖16号相近;桂糖94-116,中茎、早熟、高糖、高产,宿根性好,产蔗量较对照种增4.7%,含糖量增8.9%,甘蔗蔗糖分增0.6%。综合适应指数的计算与分析过程简洁,结果通俗易懂,可成为区试材料在各生态区域综合适应性分析的一种简便方法。

Preliminary report on regional trial for sugarcane varieties in 2003～2004 in Guangxi

In order to assess the performance of new cane lines which was bred and introduced in different locations of Guangxi, supply references to new variety breeding, evaluation and extension, regional trial with eight materials and one control were conducted at nine locations in Guangxi during 2003-2004. The results showed that as compared with the control ROC16, GT96-154 was of mid-large stalk diameter, early maturing, high yield of cane and sugar, good ratooning ability, strong resistance to drought. Its cane sugar content was close to ROC16, cane yield and sugar yield were higher than ROC with 12.4% and 10. 1%, respectively. GT96-211 was of midlarge stalk diameter, early maturing, high yield of cane and sugar, good ratooning ability, cane yield and sugar yield were 12.1% and 10. 1% higher than the control, respectively. Its cane sugar content was also close to ROC16. GT 94-116 was middle stalk diameter, early maturing, high yield of cane and sugar, good ratooning ability, and its cane yield, cane sugar content and sugar yield were higher than the control with 4.7%, 0.6%, 8.9%,respectively. Both the calculation and analysis of integrative adaptation index were simple, and the results were easy to be understood. It would be simple and convenient for analyzing integrative adaptability index of trial materials in ecoregion.
