Since Ababuna is a hybrid of 741 and Dessu, the heterosis effect resulted in creating not only high-yielding hybrid vigor variety, but also superior variety in terms of total polyphenol content.
Heterosis, or hybrid vigor, refers to the superior biological functions of F1 hybrids compared with their parental homozygous or inbred lines.
A common consequence of hybridization is hybrid vigor, or heterosis, which refers to superior performance in biomass, yield, or other agronomic traits in hybrids relative to one or both parents (Birchler et al. 2003).
Hybrid vigor is the phenomenon in which hybrids have superior performances over their parents in a number of traits such as biomass accumulation, growth rate and fertility (e.g. [ 33]).
However, at later ages hybrid vigor (or heterosis), where a first-generation hybrid displays superior phenotypic expression over their parents, was observed for body weights.
Hybrid vigor hypothesizes that crossbred plants, animals, and humans are genetically superior to their parents, since weak, undesirable, deleterious, recessive genes, which might be harmful, are suppressed.
Farmers depend on hybrid vigor for improved crop yields, as seeds produced from different strains of, say, corn, can lead to superior crops.
