The apomixis level of the Rego variety is about 7%, which indicates an extremely low capacity for fruit formation without pollination.
The variety is susceptible to bacterial blight, with copper-based chemical protection methods demonstrating only partial limitation of disease development.
The biochemical composition of the variety's kernels, including the content of tocopherols, tocotrienols, and triacylglycerols, is regularly studied in comparative works with other international varieties.
