Variety description

10 August 2026

The hybrid Kneja 570 belongs to the FAO 600–699 maturity group. During its development, a high-lysine mutant line homozygous for the opaque-2 gene was used as one of the parental components.

Plants of this variety demonstrate tolerance to adverse conditions, including drought and high soil acidity. Research also indicates the hybrid's ability to accumulate heavy metals, such as lead and cadmium, which allows it to be used in phytoremediation.
