For Italian ryegrass, plant height is measured as the distance from the soil surface to the top of the generative shoot at the flowering or full maturity stage. Trait values range from 20 to 100 cm, with typical values for most varieties falling in the 30–90 cm range.
Tall-growing forms demonstrate higher green mass yield potential, which is a decisive factor for forage use. At the same time, breeding varieties must maintain lodging resistance, while plant height also dictates the frequency of cuts and competitiveness within grass mixtures.
