Variety traits
Helianthus annuus L.
A comprehensive characteristic of the ability of a sunflower variety or hybrid to produce seed and oil yield under specific conditions. It is evaluated through seed yield, oil content, and structural elements such as 1000-seed weight and head fill.
In the reference 112 varieties crop Sunflower, where this is mentioned in the description.
Sunflower productivity is defined as a set of quantitative parameters, including seed yield in t/ha or dt/ha, as well as oil yield, calculated by multiplying seed yield by the percentage of oil content. Key structural elements of productivity include 1000-seed weight, seed filling and quantity per head, as well as their oil content.
Productivity assessment is carried out during variety trials in comparison with a standard. Absolute yield values vary significantly depending on the cultivation zone: from 2.6–2.8 t/ha under conditions of unstable moisture to significantly lower indicators in arid regions. The goal of breeding is to develop plastic genotypes capable of maintaining stable productivity and oilseed quality under changing weather conditions or cultivation technologies.
