where this is mentioned in the description.
In red cabbage, splitting is triggered by sudden fluctuations in soil moisture and delayed harvesting after reaching technical maturity. Damage to the head leads to a loss of market quality and high susceptibility of the plant to secondary infections and pests.
Within the framework of breeding and variety testing, this parameter is evaluated as a qualitative resistance trait on a scale from very low to very high. The absence of cracks is a required quality standard; therefore, during variety evaluation, the genetically determined ability of the head to maintain integrity while left in the field past maturity is recorded.
