Variety description

10 August 2026

The corn hybrid PX 39 underwent testing in the early 1980s, during which it demonstrated variable grain yield and moisture levels depending on cultivation conditions, including the use of no-till technology.

In the documentation of that period, the hybrid was mentioned as an object of research, including studies on the effects of acid rain. A detailed description of the plant's morphological traits is absent in available publications.
