Bread wheat (Triticum aestivum) is one of the most important food crops in the world. Its physiological and morphological traits are closely related to yield. Therefore, it is generally important to discover the genomic region associated with these traits. In this research, associations between 21 simple sequence repeat (SSR) markers and 10 inter-simple sequence repeat (ISSR) markers with some traits related to root structure at the embryonic and seedling stages and also some agromorphological traits at the whole plant stage were evaluated on a set of 102 wheat genotypes. A highly significant coefficient of variation among different genotypes was observed in all measured traits. A high level of polymorphism with SSR and ISSR markers was obtained. Genetic structure analysis revealed two distinct subpopulations. Significant correlations were found between genomic markers and evaluated traits. A total of nine markers, including four SSR markers in 1A, 3A, 5A and 2B chromosomal regions and five different ISSR markers were related to the studied traits. Several molecular markers were significantly associated with more than one phenotypic trait, suggesting the possible presence of pleiotropic or indirect effects. The phenotypic variation justified by these alleles ranged from 4 to 15%. Obtained genetic information can be targeted for further validation and genetic analysis in the relevant populations or other breeding sets.

面包小麦不同种质中微卫星标记与根结构和农艺性状的关联

面包小麦（小麦) 是世界上最重要的粮食作物之一。其生理形态特征与产量密切相关。因此，发现与这些性状相关的基因组区域通常很重要。在这项研究中，评估了 21 个简单序列重复 (SSR) 标记和 10 个简单序列重复 (ISSR) 标记与胚胎和幼苗阶段根结构相关性状以及整株阶段一些农艺性状之间的关联。在一组 102 种小麦基因型上。在所有测量的性状中观察到不同基因型之间高度显着的变异系数。获得了具有 SSR 和 ISSR 标记的高水平多态性。遗传结构分析揭示了两个不同的亚群。在基因组标记和评估的性状之间发现了显着的相关性。共有9个标记，包括1A、3A、5A和2B染色体区域的4个SSR标记和5个不同的ISSR标记与所研究的性状相关。几种分子标记与一种以上的表型性状显着相关，表明可能存在多效性或间接效应。这些等位基因证明的表型变异范围为 4% 至 15%。获得的遗传信息可以针对相关种群或其他育种集进行进一步验证和遗传分析。几种分子标记与一种以上的表型性状显着相关，表明可能存在多效性或间接效应。这些等位基因证明的表型变异范围为 4% 至 15%。获得的遗传信息可以针对相关种群或其他育种集进行进一步验证和遗传分析。几种分子标记与一种以上的表型性状显着相关，表明可能存在多效性或间接效应。这些等位基因证明的表型变异范围为 4% 至 15%。获得的遗传信息可以针对相关种群或其他育种集进行进一步验证和遗传分析。
