Heterosis — Soft Wheat

Triticum aestivum L.

The phenomenon of F1 hybrid superiority in soft wheat over parent forms, manifesting as increased productivity, stress adaptability, and growth indices.

In the reference 20 varieties crop Bread wheat, where this is mentioned in the description.

In soft wheat, heterosis manifests as an increase in grain weight per plant or spike, grain number, and productive tillering. When crossing genetically distant forms, such as winter and spring varieties, true heterosis for grain weight can reach 60–100% or more, with values in the 25–65% range considered significant for breeding.

In addition to yield, heterosis influences crop adaptability by increasing resistance to unfavorable environmental factors, which is assessed by root system development and seedling biomass. In breeding practice, negative heterosis for plant height is also observed and used to create semi-dwarf forms, while the advantage of F1 hybrids in a number of traits can persist through F3–F4 generations.

General information about the subject — on the page Heterosis.
