Abstract

We investigated the interaction between genotype by trait, and an experiment was conducted at the University of Debrecen. Two maize cultivars, FAO340 and FAO410, were studied in a randomized complete block design with four replications. This experiment was applied to the six fertilization treatments. Fertilizer levels were NPK0 (control) (N:0, P2O5:0, K2O:0), NPK1 (N:30, P2O5:23, K2O:27), NPK2 (N:60, P2O5:46, K2O:54), NPK3 (N:90, P2O5:69, K2O:81), NPK4 (N:120, P2O5:92, K2O:108), and NPK5 (N:150, P2O5:115, K2O:135). The first principal component showed 54.24%, and the second principal component showed 20.75%, which explained the total squares interaction using the AMMI model in the case of the FAO410 hybrid. As regards the FAO340 hybrid, the first principal component showed 58.18%, and the second principal component showed 18.04%, explaining the total squares interaction using the AMMI model in the FAO410 hybrid. In the GGE biplot on FAO410, the first and the second principal components covered 91.20% of the total data in this analysis. Accordingly, the desirable treatment was NPK5, followed by NPK4, NPK2, NPK3, NPK1, and NPK0. NPK4 and NPK5 had the most desirable treatments for the number of seeds per row, chlorophyll, weight of 1000 seeds, and stem diameter in the case of the FAO410 hybrid.

摘要

我们研究了基因型与性状之间的相互作用，并在德布勒森大学进行了一项实验。选用两个玉米品种FAO340和FAO410，采用随机完全区组设计，重复4次。该实验应用于六种施肥处理。施肥水平分别为NPK0（对照）（氮：0，五氧化二磷：0，氧化钾：0）、NPK1（氮：30，五氧化二磷：23，氧化钾：27）、NPK2（氮：60，五氧化二磷：46，氧化钾：54）、NPK3（氮：90，五氧化二磷：69，氧化钾：81）、NPK4（氮：120，五氧化二磷：92，氧化钾：108）和NPK5（氮：150，五氧化二磷：115，氧化钾：135）。对于FAO410杂交种，第一主成分贡献率为54.24%，第二主成分贡献率为20.75%，采用AMMI模型解释了总平方和交互作用。对于FAO340杂交种，第一主成分贡献率为58.18%，第二主成分贡献率为18.04%，采用AMMI模型解释了FAO410杂交种的总平方和交互作用。在FAO410的GGE双标图中，第一和第二主成分覆盖了该分析中91.20%的总数据。因此，理想的处理方式是NPK5，其次是NPK4、NPK2、NPK3、NPK1和NPK0。对于FAO410杂交种，NPK4和NPK5对于每行种子数、叶绿素、千粒重和茎粗来说是最理想的处理方式。
