【目的】研究饲草型小黑麦区域试验品种稳定性问题。【方法】应用AMMI模型对冬性饲草型小黑麦区域试验产量数据进行分析,并结合稳定性参数Di(j)和双标图对鲜、干草产量的基因型、环境和基因型与环境(G×E)互作进行分析。【结果】参试品系在各试点上总体适应性表现较强,6个参试品系中WH07-2鲜草产量上表现出既高产又稳产,适宜于作为刈割青贮品种。【结论】AMMI模型是分析基因型与环境(G×E)互作的有效方法,应用此方法对饲草型小黑麦区域试验品种(系)进行评价会更加科学完善。
【Objective】 The purpose of this study was to study the stability of forage-triticale test varieties. 【Method】 The yield data of winter forage-type triticale were analyzed by AMMI model. The genotype, environment, genotype and environment of fresh and hay yield were analyzed with the stability parameters Di (j) and double-plot (G × E) interaction analysis. 【Result】 The results showed that the overall adaptability of the tested lines was strong in all experimental plots. The yield of fresh WH07-2 in the six tested lines showed high yield and stable yield, which was suitable for mowing silage varieties. 【Conclusion】 The AMMI model is an effective method to analyze the interaction between genotypes and environment (G × E). The application of this method in the evaluation of forage tritium cultivars (lines) will be more scientific and perfect.
