The object is not an independent commercial variety. This line is used in professional breeding as genetic material to obtain hybrid forms, specifically the hybrid DKC3912.
Given that T5539Z is a proprietary parent line, publicly available data on its morphological traits, yield, or disease resistance are not published, as these characteristics are evaluated only for the final hybrids.
