Pot marigold is an ornamental plant of great importance in pharmacy and cosmetology. However, there is limited published information on the diversity of the species at both the morphological and genetic levels. This paper aimed to determine the morphological and genetic diversity of selected marigold varieties. The research focused on varieties with different flower colours, and the most important morphological features of flowers and plant height were analysed. Genetic diversity analyses were performed using start codon target (SCoT) markers. The correlation coefficients between the analysed morphological features of the studied marigold varieties showed a significant positive relationship between plant height, the number of inflorescences per plant and inflorescence diameter. Genetic analyses grouped the studied varieties according to the colour of their flowers. The results obtained in our work indicate that, despite the variability observed in morphological features, the gene pool of the analysed marigold varieties is limited. This information can be valuable for marigold breeders, particularly for selecting varieties suitable for crossbreeding in breeding programs. Additionally, it offers insights into the genetic resources of the species and highlights the importance of their bioconservation.
金盏花是一种在药学和美容学中具有重要意义的观赏植物。然而，关于该物种在形态和遗传水平上的多样性，已发表的信息有限。本文旨在确定所选金盏花品种的形态和遗传多样性。研究聚焦于具有不同花色的品种，并分析了花朵的最重要形态特征和株高。使用起始密码子靶向（SCoT）标记进行遗传多样性分析。所研究的金盏花品种的分析形态特征之间的相关系数表明，株高、单株花序数和花序直径之间存在显著正相关。遗传分析根据花朵颜色对所研究的品种进行了分组。我们工作中获得的结果表明，尽管在形态特征上观察到了变异性，但所分析的金盏花品种的基因库是有限的。这些信息对金盏花育种者可能很有价值，特别是在育种计划中选择适合杂交的品种时。此外，它提供了对该物种遗传资源的见解，并突出了其生物保护的重要性。
