Variety traits
Brassica napus L.
The hybrid vigor effect in rapeseed is manifested in the superiority of F1 hybrids over parental lines or standard varieties in terms of yield, oil content, and plant structural components. In breeding, Ogura or Polima cytoplasmic male sterility systems are used to produce these hybrids.
In the reference 3 varieties crop Rapeseed, where this is mentioned in the description.
To evaluate heterosis in rapeseed, metrics of true superiority over the best parent and competitive superiority over the zoned standard are used. Traits include seed productivity, pod number, seed set, branching, as well as oil and protein content in the seeds.
The heterosis effect on yield ranges from 20% to 109% in winter rapeseed and from 20% to 60% in spring rapeseed, with oil content potentially increasing by up to 10% and protein by up to 25%. Hybrids exhibit enhanced stress resistance, uniformity in ripening, and high responsiveness to intensive cultivation technologies.
