Heterosis refers to the increase in biomass, stature, fertility, and other characters that impart
superior performance to the F1 progeny over genetically diverged parents. The manifestation of
heterosis brought an economic revolution to the agricultural production and seed sector in the last
few decades. Initially, the idea was exploited in cross-pollinated plants, but eventually acquired
serious attention in self-pollinated crops as well. Regardless of harvesting the benefits of heterosis, a
century-long discussion is continued to understand the underlying basis of this phenomenon. The
massive increase in knowledge of various fields of science such as genetics, epigenetics, genomics,
proteomics, and metabolomics persistently provide new insights to understand the reasons for the
expression of hybrid vigor. In this review, we have gathered information ranging from classical
genetic studies, field experiments to various high-throughput omics and computational modelling
studies in order to understand the underlying basis of heterosis. The modern-day science has worked
significantly to pull off our understanding of heterosis yet leaving open questions that requires
further research and experimentation. Answering these questions would possibly equip today’s
plant breeders with efficient tools and accurate choices to breed crops for a sustainable future.
