摘要
利用2009～2010年全国甘蔗新品种区域试验广东遂溪试点2年新植的数据,应用联合分析模型的结果表明,大多数品种第2年新植的蔗茎产量和含糖量都相应较第1年低,且品种与年份间互作显著。参试品种中,粤甘24号高产、稳定性中等、居于首位,较早熟、蔗糖分较高;粤甘26号高产、较不稳定,但特早熟、蔗糖分高且稳定;其余品种产量、糖分及其稳定性表现不一。
Results of the national sugarcane varieties regional trial with 2 plant crops in Suixi, Guangdong during 2009 and 2010, were preliminarily studied in this paper, using the currently popular method based on randomized blocks model in different sites and years. It was indicated that for most of the eleven varieties tested, both cane and sugar yields in the 2nd plant year were lower than those in the 1 st plant year, and the genotype X year interaction was very significant, too. Yuegan24 had a higher yield with moderate stability, earlier maturity and higher sugar content, ranking first among all the tested varieties; Yuegan26 had a higher but less stable yield with earliest maturity, highest and stable percentage of sucrose in cane. The yield and sugar content of the other tested varieties and their stability was diverse.
