Abstract

Hybrid seeds, which exploit heterosis, have driven agricultural productivity gains since the 1920s. Understanding the genetics and molecular biology of hybrid generation led to the development of modern hybrid systems. With time, modern hybrid systems integrated advanced genomic tools such as CRISPR/Cas, marker-assisted selection (MAS), and genomic selection (GS) with established technologies like cytoplasmic male sterility (CMS), restorer-of-fertility (Rf) systems, and chemical hybridizing agents (CHAs) for better hybrid production in a shorter time. Moreover, the integration of emerging approaches leveraging artificial intelligence and machine learning (AI/ML) for trait prediction, multi-parent populations to expand genetic diversity, and epigenetics to engineer climate-resilient hybrids with enhanced stress tolerance is also being explored. However, regulatory hurdles, such as divergent global policies for genetically modified (GM) hybrids, intellectual property (IP) disputes, and restricted germplasm exchange under access-and-benefit-sharing frameworks like the Nagoya Protocol, hinder innovation. Climate change exacerbates both biotic and abiotic stresses, disrupts production zones, and threatens pollinator-dependent crops, while socio-economic barriers limit the adoption of smallholder farming. Case studies of different crops demonstrate the success of hybrids, yet gaps in scalability and accessibility persist. Overall, realizing the potential of hybrid technology hinges on sustained collaboration across scientific, industrial, and policy domains to overcome technical, environmental, and socio-economic constraints. This review examines various techniques for hybrid production that incorporate genomics, future advancements, and synergies between synthetic biology, automation, and predictive breeding, as well as policies that strike a balance between intellectual property protection and germplasm accessibility for hybrid seed production.
