【摘要】 本研究探讨不同灌水模式对旱地小麦新品种产量及品质的影响，为新品种的推广提供理论依据。选取4个旱地小麦品种，设置越冬水（E₁）、越冬水+拔节水（E₂）、越冬水+拔节水+开花水（E₃）3种灌水模式，采用随机区组设计，重复3次。结果表明，不同品种的产量性状和品质性状均存在基因型效应（G）、灌水模式效应（E）和基因型×灌水模式互作效应（GE），且均表现差异显著，基因型效应（G）的变异范围为1.34%～82.73%，灌水模式效应（E）的变异范围为3.73%～83.10%，基因型×灌水模式互作效应（GE）的变异范围为0.79%～29.60%；其中，越冬水+拔节水（E₂）对产量和品质的提升效果最显著。综合产量表现，以产量为导向的品种选择顺序为‘泰科麦32’>‘泰科麦30’>‘洛旱7号’>‘鲁麦21’，而兼顾优质高产的首选品种为‘泰科麦30’；在水资源允许的情况下，建议优先在拔节期灌溉，使小麦的产量和品质得到同步提高。更多还原

【Abstract】 This study investigated how different irrigation regimes affect yield and quality traits of new dryland wheat varieties with distinct genotypes, providing theoretical support for cultivar selection and cultivation practices. A randomized block design with three replications was adopted, incorporating two factors: variety（four genotypes） and irrigation regime（E₁ wintering water only; E₂ wintering + jointing water; E₃ wintering +jointing + flowering water）. Significant genotype（G）, irrigation（E）, and genotype × irrigation interaction（GE）effects were detected across all yield and quality traits. The contribution rates varied as follows: G（1.34%-82.73%）, E（3.73%-83.10%）, and GE（0.79%-29.60%）. The E₂ treatment（wintering + jointing water） showed the greatest improvements in both yield and quality among the tested irrigation regimes. For yield-oriented production, cultivar performance ranked:‘Taikemai 32’>‘Taikemai 30’>‘Luohan 7’>‘Lumai 21’.‘Taikemai 30’emerged as the optimal cultivar balancing high yield with superior quality. Where water resources permit, jointing-stage irrigation（E₂） is recommended to simultaneously boost both yield and grain quality.更多还原
