Variety traits
Brassica oleracea L. (White Cabbage Group)
Head splitting in white cabbage is the rupturing of cover leaves that lose elasticity due to over-ripening or sudden fluctuations in moisture. This trait is a key criterion for the marketability and storability of a variety within the framework of state variety testing.
In the reference 405 varieties crop White cabbage, where this is mentioned in the description.
The physiological process is caused by the fact that the outer leaves cannot keep pace with the growth of the internal head tissues. Damaged heads become unmarketable and lose their suitability for long-term storage and processing, as pests and pathogens enter through the cracks, triggering product decay.
In the state variety testing system, resistance to splitting is evaluated under field conditions prior to harvest. The level of resistance of a variety sample is determined by calculating the percentage ratio of split heads to the total number of plants in the trial plot, taking into account adherence to harvest timelines.
