The integration of these genomic tools with traditional breeding methods accelerates the development of superior peanut cultivars. 6.2 Integrating omics data for trait improvement The integration of multi-omics data, including genomics, transcriptomics, proteomics, metabolomics, and phenomics, provides a comprehensive understanding of the biological processes underlying peanut traits. This holistic approach allows for the elucidation of growth, senescence, yield, and stress responses in peanuts (Yang et al., 2021; Huang et al., 2023). By combining data from different omics layers, researchers can construct models to predict complex traits and identify key regulatory networks. This integration is crucial for developing peanut varieties with enhanced traits such as disease resistance, drought tolerance, and improved nutritional content (Mahmood et al., 2022; Chao et al., 2023). 6.3 High-throughput phenotyping and genotyping High-throughput phenotyping and genotyping technologies are revolutionizing peanut breeding by enabling the rapid and accurate collection of large-scale data. These technologies facilitate the identification of phenotypic traits through various sensors and imaging techniques, which are then correlated with genotypic data to uncover the genetic basis of important agronomic traits (Zhao et al., 2019). The use of high-throughput genotyping, such as single nucleotide polymorphism (SNP) arrays and sequencing technologies, allows for the precise mapping of genetic variations and the identification of candidate genes for targeted breeding (Pandey et al., 2014; Tong and Nikoloski, 2020). This approach significantly shortens the breeding cycle and enhances the efficiency of selecting elite genotypes. 6.4 Role of bioinformatics and data management Bioinformatics plays a critical role in managing and analyzing the vast amounts of data generated from high-throughput phenotyping and genotyping. Advanced bioinformatics tools and platforms are essential for integrating and interpreting multi-omics data, enabling researchers to identify key genetic markers and regulatory networks associated with desirable traits (Marsh et al., 2021). Effective data management systems are necessary to store, retrieve, and analyze large datasets, facilitating the translation of research findings into practical breeding applications. The development of comprehensive databases and user-friendly tools ensures that breeders can access and utilize this information to develop climate-resilient and high-yielding peanut varieties (Naqvi et al., 2022; Chao et al., 2023). 7 Future Perspectives in Peanut Genetic Improvement 7.1 Climate-resilient peanut varieties The development of climate-resilient peanut varieties is crucial to ensure food security in the face of changing environmental conditions. Recent advancements in peanut genomics have enabled the identification of genes associated with tolerance to abiotic stresses such as drought and salinity. For instance, the integration of genomic selection and speed breeding techniques holds promise for the rapid development of climate-smart peanut varieties (Pandey et al., 2020). Additionally, the utilization of wild Arachis species, which possess significant variability for stress resistance, can be instrumental in breeding programs aimed at enhancing climate resilience (Sharma et al., 2017). 7.2 Sustainable peanut farming practices Sustainable farming practices are essential to minimize the environmental impact of peanut cultivation. The introduction of disease-resistant cultivars, such as those enhanced with genetics from Arachis cardenasii, has already demonstrated reduced fungicide use and improved food security (Bertioli et al., 2021). Furthermore, the development of core and mini core collections can facilitate the use of diverse genetic resources, promoting sustainable agricultural practices by reducing the reliance on a narrow genetic base (Upadhyaya et al., 2002). The adoption of molecular breeding techniques, including marker-assisted selection, can also contribute to the development of high-yielding, disease-resistant varieties, thereby supporting sustainable farming (Holbrook et al., 2011).
