“…The Inhibition of Alien Pollen gene has been used to produce interspecific hybrids with species from sections Chaetosorghum, Parasorghum, and Stiposorghum, overcoming pre-fertilization barriers. Post-fertilization barriers can be eliminated through embryo rescue techniques and the use of 2n gametes, allowing for gene transfer between species" [8].…”

Wide hybridization in crop plants involves crossing two distantly related species to initiate desirable traits, such as disease resistance, into a cultivated crop. This technique expands the genetic diversity accessible for breeding programs, enhancing the adaptability and resilience of crops. Wide hybrids often surpass limitations of conventional breeding by incorporating unique genetic material. However, difficulties arise due to reproductive barriers and genomic incompatibilities between divergent species. Researchers employ techniques like embryo rescue and tissue culture to overcome these hurdles. Despite its potentiality, wide hybridization requires careful selection and extensive backcrossing to stabilize desired traits. The resulting crops may show improved resistance to pests, diseases, or environmental stressors, contributing to sustainable agriculture and food security. Continuous advancements in molecular biology and genomics facilitate the identification and transfer of specific genes, accelerating the development of wide hybrid varieties with enhanced agronomic traits.

Wide hybridization, the crossing of genetically distant species or genera, has emerged as a pivotal strategy in crop improvement, offering the potential to introduce desirable traits and enhance genetic diversity. This review examines the advancements, challenges, and future prospects of wide hybridization in crop breeding. Wide hybridization has facilitated the incorporation of traits such as disease resistance, abiotic stress tolerance, and improved nutritional profiles into various crops. These hybrids can often express hybrid vigour, leading to increased yield and robustness. However, the process presents significant challenges, including reproductive barriers, hybrid sterility, and genomic incompatibilities. Advances in molecular biology and biotechnology, such as marker-assisted selection, genomic sequencing, and embryo rescue techniques, have played a crucial role in overcoming these barriers, making wide hybridization more feasible and effective. Additionally, the review highlights case studies of successful wide hybridization efforts in key crops like wheat, rice, and legumes, displaying the tangible benefits and contributions to food security and agricultural sustainability. Future prospects focus on the integration of cutting-edge technologies like CRISPR-Cas9 and genomic selection to further streamline the process and enhance the precision of trait incorporation. The collaboration between traditional breeding techniques and modern biotechnological approaches holds promise for addressing the growing challenges in global agriculture. This review underscores the importance of continued research and innovation in wide hybridization to unlock its full potential and drive the next generation of crop improvement strategies, ensuring resilient and productive agricultural systems in the face of climate change and population growth.
