This approach leverages high-density genetic linkage maps, QTL mapping, and genome-wide association studies (GWAS) to pinpoint genes and genomic regions that contribute to yield, stress tolerance, and other agronomic traits. The availability of whole-genome sequences and high-throughput genotyping platforms has made it possible to perform comprehensive integrative analyses, leading to more efficient breeding strategies (Bohra et al., 2014a; Bohra et al., 2014b; Bhat et al., 2018). 5.2 Systems biology and computational approaches Network analysis and modeling are powerful tools in systems biology that help to understand the complex interactions between genes, proteins, and metabolic pathways. By constructing and analyzing biological networks, researchers can identify key regulatory nodes and pathways that control important traits in pulse crops. These insights can guide the development of targeted breeding strategies and the engineering of metabolic pathways to enhance crop productivity (Morrell et al., 2011; Abberton et al., 2015). Predictive modeling uses computational approaches to forecast the performance of different genotypes under various environmental conditions. This approach integrates genomic, phenotypic, and environmental data to create models that predict how different genetic combinations will perform in the field. Predictive modeling can help breeders select the best genotypes for specific environments, thereby improving the efficiency and effectiveness of breeding programs (Morrell et al., 2011; Bevan et al., 2017; Nerkar et al., 2022). 5.3 Translational genomics and field applications Translational genomics involves applying discoveries made in the laboratory to real-world agricultural settings. Several case studies have demonstrated the successful translation of genomic research into field applications. For instance, the Pigeonpea Genomics Initiative (PGI) has developed a range of genomic resources, including mapping populations and molecular markers, which have been used to breed pigeonpea varieties with improved yield and stress tolerance (Varshney et al., 2009). Similarly, genomics-assisted breeding has led to the development of high-yielding and resilient pulse crop varieties in various developing countries (Bohra et al., 2014a; Bohra et al., 2014b). Despite the significant progress in genomics and molecular breeding, several challenges remain. These include the need for better integration of genomic data with phenotypic and environmental information, the development of more efficient transformation and regeneration systems, and the adaptation of genomic tools to a wider range of pulse crops. However, the opportunities are immense, with genomics offering unprecedented potential to enhance crop yield, quality, and resilience. Continued investment in genomic research and the development of innovative breeding strategies will be crucial for meeting the global food demand in the face of climate change and other challenges (Abberton et al., 2015; Altpeter et al., 2016). 6 Economic and Environmental Impacts of Genomic Advances in Pulse Crops 6.1 Economic benefits for farmers and stakeholders Genomic interventions in pulse crops have shown significant economic benefits for farmers and stakeholders. The adoption of genomics-assisted breeding (GAB) has led to the development of high-yielding, stress-tolerant pulse varieties, which directly translates to increased productivity and profitability for farmers. For instance, the use of high-throughput genotyping and sequencing platforms has enabled the identification of desirable traits, leading to the rapid development of improved cultivars (Bohra et al., 2014). This has resulted in higher yields and reduced losses due to environmental stresses, thereby enhancing farmer profits. Additionally, the meta-analysis of genetically modified (GM) crops indicates that such technologies can reduce chemical pesticide use by 37%, increase crop yields by 22%, and boost farmer profits by 68% (Klümper and Qaim, 2014). These findings suggest that similar economic benefits can be expected from the application of genomics in pulse crops. The market impact of genomic advances in pulse crops is substantial, with increased adoption rates observed among farmers. The availability of whole-genome sequences and high-density genetic linkage maps has facilitated the development of superior pulse varieties, which are more resilient to climate change and environmental stresses
