Hybrid vigour, or heterosis, remains a cornerstone of modern plant breeding, promising enhanced growth, yield and stress tolerance in agriculturally important species. Recent studies have been ...

AMES, Iowa – An Iowa State University agronomist has helped uncover the genetic mechanisms in sorghum plants that allow hybrids to perform better than parent varieties, a process known as heterosis.

When two homozygous plant lines with different characteristics are crossed, the resulting offspring are often more robust and productive than their parents. This phenomenon is called heterosis. It can ...
