摘要
【目的】研究玫瑰(Rosa rugosa Thunb.)不同品种单株产花量的年度稳定性问题。【方法】选用13个玫瑰品种,采用随机区组试验设计,4次重复,每小区10～12株,连续两年测定各品种的单株产花量,应用AMMI(additive main effects and multiplicative interaction,又称为主效可加互作可乘)模型对连续两年的单株产花量的基因型、环境和基因型与环境(G×E)互作进行了探讨。【结果】基因型、环境及G×E互作的平方和分别占总平方和的65.610%、12.352%、22.038%,均达极显著水平,而误差仅占2.75×10-17%,参试品种的单株产花量在500～1500g;AMMI双标和排序图表明,紫云、玉盘、唐紫、唐粉、紫枝玫瑰、朱龙游空与2006年的环境互作为正,而与2007年的环境互作为负;赛西子、唐红、西子、紫芙蓉、朱紫双辉、紫雁、香刺果与2007年的环境互作为正,与2006年的环境互作为负。AMMI品种适应性分析显示,朱龙游空、唐紫和赛西子具有最佳适应性。【结论】AMMI模型很好地解释了玫瑰品种产量性状的基因型效应、环境效应和G×E互作效应。根据分析结果可以得出以下结论,单株产花量高且稳定的品种有西子、紫芙蓉和赛西子(1200～1800g),相对稳定的品种有玉盘、唐粉、紫枝玫瑰、紫云、紫雁和朱紫双辉(800～1150g),高产但较不稳定的品种有唐紫和朱龙游空(1700～2600g),产量低也不稳定的品种是唐红和香刺果(500～600g)。
【Objective】The aim of this research is to study the stability of flower yield/plant of rugosa rose cultivars in different years. Thirteen rugosa rose cultivars were tested,randomized completed block design with 4 replicates and 10-12 individuals for each replicate was employed in this experiment. 【Method】The flower yield/plant during the continuous two years was measured and analyzed by AMMI （additive main effects and multiplicative interaction） model. The article discussed the genotype,environment and interactive effects of genotype by environment （G×E） of flower yield/plant. 【Result】 The results showed that the proportions of the sum of squares of genotype,environment and G×E interactive effects on total sum of squares was 65.610%,12.352%,22.038% respectively,the error only 2.75×10^-17%. And there were significant effects in genotype,environment and G×E interaction. The flower yield/plant in the 13 cultivars was mainly between 500-1 500 g. AMMI plots and taxis plots showed that there were positive interaction effects of cultivars R. rugosa Purple Cloud,R. rugosa Jade Plate,R. rugosa Tang Purple,R. rugosa Tang Pink,R. rugosa Purple Branch,R. rugosa Puce Dragon by environment in 2006 and negative by environment in 2007,positive interaction effects of cultivars R. rugosa Saixizi,R. rugosa Tang Red,R. rugosa Xizi,R. rugosa Zifurong,R. rugosa Zhuzishuanghui,R. rugosa Purple Goose,R. rugosa Xiangciguo by environment in 2007 and negative by environment in 2006. The adaptability analysis revealed that R. rugosa Puce Dragon,R. rugosa Tang Purple,R. rugosa Saixizi were optimal adaptation to environment. 【Conclusion】AMMI model explained clearly the genotype,environment and G×E interactions on yield trait in rugosa rose cultivars. It is concluded that the most stable and high output cultivars were R. rugosa Xizi,R. rugosa Zifurong and R. rugosa Saixizi （1 200-1 800 g）. The relative stable ones were R. rugosa Jade Plate,R. rugosa Tang Pink,R. rugosa Purple Branch,R. rugosa Purple Cloud,R. rugosa Purple Goose and R. rugosa Zhuzishuanghui （800-1 150 g）. The high yield but less unstable cultivars were R. rugosa Tang Purple and R. rugosa Puce Dragon （1 700-2 600 g）. The lower yield and unstable cultivars were R. rugosa Tang Red and R. rugosa Xiangciguo （500-600 g）.
