Abstract

Abstract. The present study was carried out to select adapted and stable durum wheat (Triticum durum Desf.) genotypes for grain yield and thousand kernel weight using various stability parameters. Based on the graphical distributions between the parametric indices (Wricke’s ecovalence stability index (Wi²), environmental coefficient of variance (CVi), mean variance component (θᵢ)) and the mean grain yield of tested genotypes, the suitable genotype for the tested conditions was Mexicali 75. Further, the cultivars Oued Zenati and Bousselem were the most adapted with the highest TKW. With non-parametric index was classified genotype Mexicali 75 as the most stable with high grain yield. According to PCA analysis the genotype Altar 84 was classified in dynamic stability group with the highest grain yield in addition, cultivars Bousselem and Oued Zenati were classified in dynamic concept with the highest thousand kernel weight. The results of this study confirmed that the parametric and non-parametric methods are the suitable tools to identify the most stable durum wheat (Triticum durum Desf.) under semi-arid conditions.

半干旱条件下硬粒小麦(Triticum durum Desf.)基因型产量和千粒重的稳定性分析
摘要本研究利用不同的稳定性参数,筛选适应稳定的硬粒小麦(Triticum durum Desf.)籽粒产量和千粒重基因型。根据Wricke生态稳定性指数(Wi²)、环境方差系数(CVi)、平均方差分量(θ θ)与各基因型平均产量的图形分布,确定了适合试验条件的基因型为Mexicali 75。此外,品种Oued Zenati和Bousselem的适应性最强,TKW最高。经非参数指标鉴定,墨西卡利75基因型为最稳定高产品种。通过主成分分析,将“坛84”基因型划分为动态稳定组,产量最高;将“布塞勒姆”和“泽纳蒂”基因型划分为动态稳定组,千粒重最高。本研究结果证实,参数和非参数方法是半干旱条件下最稳定硬粒小麦(Triticum durum Desf.)鉴定的合适工具。
