These populations are better able to exploit local soil and climatic conditions, resulting in improved yield stability across different seasons and regions. Such case studies underscore the potential of evolutionary breeding as a robust strategy to increase the genetic fitness of cereals, thereby ensuring food security in an era of climate change. The concept and application of evolutionary breeding, as discussed by Döring et al. (2011), provide a solid foundation for implementing this approach in global agricultural practices. By continuing to study and apply these principles, plant breeders can better equip crops to handle the unpredictable stresses associated with global climate variations. 3 Advanced Genetic Techniques 3.1 Whole-genome strategies for marker-assisted breeding and their impact on plant breeding efficiency The adoption of whole-genome strategies for marker-assisted breeding has significantly revolutionized plant breeding by enhancing efficiency and precision. Xu et al. (2012) elaborate on how molecular breeding for complex traits in crops necessitates an understanding and manipulation of myriad factors that influence plant growth and stress responses. These strategies employ full genome sequencing and genome-wide molecular markers to address various genomic and environmental factors comprehensively. This holistic approach is crucial in the effective application of genetic resources and breeding materials, optimizing the selection for desirable traits through a detailed understanding of specific genomic regions, genes/alleles, haplotypes, and their phenotypic contributions (Xu et al., 2012). 3.2 The development and use of multi-parent populations (MAGIC) for genetic analysis and selection Multi-parent advanced generation inter-cross (MAGIC) populations represent a cutting-edge approach in genetic analysis and selection, offering a robust tool for the dissection of complex traits. Arrones et al. (2020) discuss the construction of MAGIC populations, which involves the intermingling and recombination of genomes from multiple founder parents. This results in a set of recombinant inbred lines that display a lack of genetic structure and high genetic and phenotypic diversity. The strength of MAGIC populations lies in their ability to combine significant levels of genetic recombination, thus providing a powerful resource for the genetic analysis of quantitative traits and the selection of elite breeding material. These populations have proven particularly valuable in crop species where complex traits are a focus, allowing breeders to achieve more targeted and efficient selection outcomes (Arrones et al., 2020). The development and implementation of these advanced genetic techniques are crucial for the future of plant breeding, enabling researchers and breeders to enhance crop varieties with greater precision and efficiency, ultimately contributing to sustainable agricultural practices and food security. 4 Integrating Microbiomes in Plant Breeding 4.1 The potential of microbiomes in enhancing genetic variability and plant fitness Recent research highlights the significant role of microbiomes in enhancing the genetic variability and fitness of plant populations. Gopal and Gupta (2016) emphasize that plants, though stationary, have developed intricate relationships with microbial communities to counter various biotic and abiotic stresses. These symbiotic relationships not only bolster plant resilience but also introduce a critical source of genetic variability. Microbiomes, particularly those in the rhizosphere and phyllosphere, play pivotal roles in nutrient uptake, disease resistance, and stress tolerance, contributing to the overall adaptability and health of plants. By harnessing these microbial interactions, plant breeders can exploit an untapped reservoir of genetic diversity to enhance crop performance under diverse environmental conditions (Gopal and Gupta, 2016). 4.2 Strategies for incorporating microbiome selection into traditional plant breeding frameworks To integrate microbiomes effectively into plant breeding, it is essential to develop strategies that consider both the plant and its associated microbial communities as a single holistic unit. One approach is the use of microbial inoculants as a breeding tool, where specific beneficial microbes are introduced to the plant during critical growth
