Non-Dormant (DR 9-11)

Description: These varieties continue to grow later into the fall and break dormancy very early in the spring. They are highly productive year-round but have little winter hardiness. Best For: Warm, southern climates (e.g., California, Arizona) where continuous growth is desired.

Semi-Dormant (DR 5-8)

Description: The most popular type. These varieties slow or stop growth in the fall to prepare for winter, providing excellent winter survival while maintaining high-yield potential during the growing season. Best For: Temperate regions and the Upper Midwest, offering the best balance of yield and persistence.

Dormant (DR 1-4)

Description: Varieties that stop growing early in the fall and remain completely dormant until spring. They exhibit maximum winter hardiness but typically offer one less cutting per season than semi-dormant types. Best For: Very cold regions and the Northern Great Plains (e.g., Montana, North Dakota).

Trait: Genetically modified to contain less lignin (the indigestible fiber in the cell wall).

Benefit: Allows for a wider harvest window and provides greater digestibility, leading to higher animal performance (milk/weight gain) without sacrificing yield.

Trait: Bred for specific resistance to common regional threats like the Potato Leafhopper (PLH)Aphanomyces Root Rot (ARR), and various Nematodes.

Benefit: Provides persistence and higher reliable yields by minimizing plant damage and stand loss. Look for varieties rated R (Resistant) or HR (Highly Resistant).

Trait: Developed to perform better in soils with high concentrations of dissolved salts.

Benefit: Expands the viable acreage for alfalfa production in arid or irrigated regions prone to salinity issues.
