Abstract

Heterosis is a natural phenomenon in which offspring of distinct species or offspring of species hybrids exhibit better biomass, faster rates of growth, and higher fertility than either of their parents. In comparison to either parents or their self-pollinated cousins, the offspring of two homozygous inbred lines are more robust and have bigger heights and weights. With naturally cross-pollinating species the degree of heterosis is frequently higher than in self-pollinating crop. One of the most significant advancements in agriculture was the development of hybrids. Today, heterosis is widely used without having a thorough understanding of the underlying molecular and genetic concepts. By enabling the best possible exploitation of crop yield and stability, the understanding of the genetic and epigenetic framework underlying heterosis would be a major discovery that would revolutionize current plant breeding.
