Variety traits
Pelargonium zonale (L.) L'Hér.
The heterosis effect in Pelargonium zonale manifests during interspecific hybridization, leading to increased vigor and improved vegetative characteristics of first-generation hybrids.
In the reference 3 varieties crop Horseshoe pelargonium, where this is mentioned in the description.
The manifestation of heterosis in Pelargonium zonale is most pronounced when crossing with other species, such as Pelargonium tongaense. First-generation (F1) hybrids exhibit a significant increase in vigor and a qualitative improvement in a range of vegetative characteristics.
In breeding programs, the heterosis effect is utilized as a biological mechanism to achieve enhanced ornamental and production traits, including growth rate, plant habit, and the number and strength of peduncles. Specific quantitative indicators or standardized scales for assessing the heterosis index in this crop are currently absent in professional literature.
