Variety description

10 August 2026

The Phhb4 line is an inbred line of yellow dent corn used for creating first-generation hybrids. The plant is characterized by an acceptable height and ear placement, as well as the ability to adapt to various moisture conditions, showing an advantage in wet seasons.

In terms of phytosanitary resistance, the line possesses resistance to common rust and stalk lodging, although it may exhibit susceptibility to gray leaf spot. In scientific research, Phhb4 is often used as genetic material for analyzing resistance to Fusarium and evaluating hybrid performance.
