Variety description

10 August 2026

The hybrid is an oilseed crop; in breeding and physiological experiments, indicators such as oil content, number of achenes per head, and 100-seed weight are studied. The variety is researched as a salt-tolerant genotype, and studies on its response to drought and heavy metal exposure have also been conducted.

The plant possesses resistance to white mold and whitefly, and a lower susceptibility to leaf miners is noted. The hybrid is often used in experimental work to evaluate the efficacy of growth regulators and the influence of various stress factors.
