Variety description

10 August 2026

The hybrid appears in scientific papers dedicated to studying the influence of sowing dates on plant development, particularly on flowering time, maturity, and overall productivity. According to the research results, sowing dates did not have a statistically significant effect on the oil content percentage in the seeds of this hybrid.

Detailed morphological characteristics, such as plant height, as well as official technical documentation and data on disease resistance, are absent in available publications. The hybrid is classified as rare and is considered obsolete for modern industrial production.
