The formation of adaptive traits is affected by many environmental and genetic factors, and its genetic diversity is of great significance to the adaptive ability and genetic improvement of Triticeae crops. This study summarized the genetic diversity of adaptive traits in Triticeae crops and its evaluation methods. In particular, the use of molecular marker technologies such as single nucleotide polymorphism (SNP) and simple sequence repeat (SSR) in the assessment and utilization of these traits, Molecular markers not only reveal the complexity of genetic diversity, but also accelerate the study of genes associated with adaptive traits, providing a powerful tool for molecular assisted breeding. Bioinformatics methods combined with molecular markers will further promote the study of adaptive traits of Triticeae crops, and provide a scientific basis for coping with climate change and improving food security. Keywords Triticeae crops; Adaptive traits; Genetic diversity; Molecular marker; Bioinformatics In the context of global food security challenges, Triticeae crops, as one of the staple foods of mankind, play an irreplaceable role in ensuring the stability of food supply and responding to the needs of the growing population. Triticeae, including wheat, barley, rye, etc., not only accounts for an important share of global food production, it is also a key source of animal feed and biomass energy (Angus et al., 2015). With the increasing impact of climate change on agricultural production conditions, the study of adaptive traits of Triticeae crops has become an important scientific frontier to ensure food security.. Adaptive traits, including but not limited to drought resistance, saline-alkali tolerance, disease resistance and the ability to adapt to extreme climatic conditions, are the key factors for Triticeae crops to survive and reproduce in changeable environments. These traits not only directly affect the growth and development of crops, but also directly affect the yield of crops. It is also of great significance for improving crop stress resistance, reducing the impact of agriculture on the environment and promoting sustainable agricultural development (Blum, 2014). The purpose of this study was to investigate the genetic diversity of adaptive traits in Triticeae crops and the application and discovery of molecular markers in this process. Through an in-depth analysis of the adaptive responses of Triticeae crops to different environmental stresses, this study aims to reveal those key genetic factors, how they regulate the adaptive responses of crops, and how this knowledge can be used to guide future breeding efforts. In the context of molecular marker technology as a powerful tool to help scientists identify genes associated with important agronomic traits (Ha et al., 2022) and thus accelerate crop improvement procedures, this study will detail the application of molecular marker technology in the assessment of genetic diversity. Barley Research on adaptive traits of Triticeae crops and their genetic diversity is of far-reaching significance for optimizing agricultural production, improving crop yield and quality, and coping with global climate change. By exploring the genetic potential of Triticeae crops, researchers can not only enhance crop stress resistance, but also provide scientific basis and technical support for sustainable agricultural development.
