许多研究表明,杂种小麦在产量和主要品质性状上存在显著的基因型与环境互作,杂种小麦比纯系品种更能适应变化的环境条件,表现出更好的稳定性。但是,关于杂种小麦优于纯系品种所表现出的杂种优势在不同环境中的表现则报道很少。正如一种性状的表现型由
Many studies have shown that hybrid wheat has significant genotype and environmental interactions in yield and quality traits. Hybrid wheat is more stable than pure lines in adapting to changing environmental conditions. However, there are few reports on the heterosis exhibited by hybrid wheat over pure lines in different environments. Just as the phenotype of a trait consists of
