Variety description

10 August 2026

The Diamond variety was used in scientific research as an initial population to evaluate the effectiveness of breeding for survival under continuous grazing conditions. Within the framework of these studies, the variety was compared with other samples when investigating resistance to grazing and hay harvesting.

Detailed morphological characteristics of the plant, such as height or maturity group, are absent in available publications. There is also no information on product quality indicators, such as protein content or digestibility for this variety.
