Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn) is an important underutilized coarse cereal, grown for its excellent nutritional, health value and therapeutic effects. Despite its growing demand, there are limited studies that have focused on its genotypic variability and genotype-environmental interaction (GEI), particularly in the North-Western Himalayas. This study evaluated 24 Tartary buckwheat genotypes across five specific test environments (E1-E5) for 9 agronomic and 6 nutritional traits to estimate the effects of genotype (G), environment (E) and their interaction (GEI) using Additive Main Effects and Multiplicative Interaction (AMMI), Genotype and Genotype × Environment Interaction (GGE) biplot, Weighted Average of Absolute Scores (WAAS), Best Linear Unbiased Prediction (BLUP) and the Multi-Trait Stability Index. The results revealed significant GEI effects for all the evaluated traits. High heritability and genetic advance as a percentage of the mean for number of seeds per plant and seed yield per plant, suggested strong potential for genetic improvement. Based on mean performance, AMMI, WAAS, WAASBY and GGE analysis, genotypes G2, G13, G19, G1, G15 and G23 were found fairly stable alongside superior trait performance and nutritional content. Environmental analysis highlighted E2, E5 and E4 at Palampur (H.P.), as the most representative and discriminating environments. Multi-trait stability index analysis identified genotypes G2, G13, G1 and G19 as the most stable and ideal. These findings provide critical insights into the adaptability and performance of buckwheat genotypes under diverse agro-climatic conditions. Hence, these genotypes can serve as valuable resources for breeding programs aimed at developing high-yielding, nutritionally enhanced Tartary buckwheat varieties suitable for the North-Western Himalayan region.
苦荞（Fagopyrum tataricum (L.) Gaertn）是一种重要的未得到充分利用的粗粮，因其卓越的营养、健康价值和治疗功效而被种植。尽管其需求不断增长，但针对其基因型变异和基因型-环境互作（GEI）的研究有限，特别是在喜马拉雅山脉西北部地区。本研究在五个特定试验环境（E1-E5）中对24个苦荞基因型的9个农艺性状和6个营养性状进行了评估，以使用加性主效应和乘积互作（AMMI）、基因型和基因型×环境互作（GGE）双标图、绝对得分加权平均值（WAAS）、最佳线性无偏预测（BLUP）和多性状稳定性指数来估计基因型（G）、环境（E）及其互作（GEI）的效应。结果显示，所有评估性状均存在显著的GEI效应。单株种子数和单株种子产量的高遗传力和遗传进展占均值的百分比表明遗传改良潜力巨大。基于平均表现、AMMI、WAAS、WAASBY和GGE分析，发现基因型G2、G13、G19、G1、G15和G23相当稳定，同时具有优良的性状表现和营养成分。环境分析突出了位于喜马偕尔邦帕拉姆布尔的E2、E5和E4是最具代表性和区分性的环境。多性状稳定性指数分析确定基因型G2、G13、G1和G19是最稳定和理想的。这些发现为苦荞基因型在不同农业气候条件下的适应性和表现提供了关键见解。因此，这些基因型可作为有价值的资源，用于旨在培育适合喜马拉雅山脉西北部地区的高产、营养强化苦荞品种的育种计划。
