摘要

多环境产量试验和多性状稳定性分析对于确定优良基因型至关重要。本研究旨在利用加性主效应和乘性互作（AMMI）、基因型加环境基因型（GGE）双图分析和多性状稳定性指数（MTSI）评估水稻基因型的适应性和稳定性。本研究在 2020-21 年期间对同一地点的 20 个水稻基因型进行了三季评估。根据 AMMI 分析，发现基因型 G22（Vandana）、G32（IC-0098989）、G34（IC-0135769）、G60（ADT 36）、G61（ADT 37）和 G64（ADT 45）产量高且更稳定。GGE 分析显示，高产且稳定的基因型为 G22（Vandana）、G34（IC-0135769）、G60（ADT 36）和 G64（ADT 45）。根据多性状稳定指数（MTSI）观察，基因型 G65（ADT 48）、G60（ADT 36）、G38（IC-0135529）和 G33（IC-0124198）比较稳定。综上所述，G60（ADT 36）不仅在产量上，而且在其他重要农艺性状上，在所有季节都是稳定的。

Detection of superior rice genotypes and yield stability using AMMI and MTSI models

Multi-environment yield trials and multi-trait stability analyses are essential to identify the superior genotype. The aim of this research was to assess the adaptation and stability of rice genotypes using additive main effect and multiplicative interaction (AMMI) and genotype plus genotype by environment (GGE) biplot analysis and multi-trait stability index (MTSI). In this study, 20 rice genotypes were evaluated for three seasons at the same location during 2020–21. Based on AMMI analysis, the genotypes G22 (Vandana), G32 (IC-0098989), G34 (IC-0135769), G60 (ADT 36), G61 (ADT 37), and G64 (ADT 45) were found to have high yield and were more stable. GGE analysis revealed that the high-yielding and stable genotypes were G22 (Vandana), G34 (IC-0135769), G60 (ADT 36), and G64 (ADT 45). The genotypes G65 (ADT 48), G60 (ADT 36), G38 (IC-0135529), and G33 (IC-0124198) were observed to be stable based on the Multi Trait Stability Index (MTSI). Based on the above, G60 (ADT 36) could be concluded as stable across all seasons, not only based on yield but also other important agronomic traits.
