Variety traits
Brassica oleracea L. (White Cabbage Group)
The manifestation of hybrid vigor in F1 white cabbage hybrids, expressed as superiority over parental forms in terms of yield, biometric parameters, processability, and disease resistance.
In the reference 3 varieties crop White cabbage, where this is mentioned in the description.
Heterosis in cabbage is evaluated by comparing F1 hybrids with parental lines or a standard. Yield, weight, head diameter and density, as well as maturity dates and disease resistance are measured in percentages. Positive heterosis for yield is often 15–30% or higher, providing increased plant uniformity, which is important for mechanized harvesting.
Negative heterosis has agronomic significance when evaluating resistance to black rot (Xanthomonas campestris); values from -18.2% to -34.0% indicate increased resistance to the disease. When studying resistance via hydathodes, values varied from -67.5% to +108.3%, which indicates complex genetic control of the trait.
The use of heterotic hybrids, created based on self-incompatible lines or CMS, increases plant adaptability to adverse environmental conditions and allows for the production of yields suitable for long-term storage and processing. Utilizing this effect allows for shortening the time to reach technical maturity by 5–7 days.
