WL Research has shown that you can't always rely on RFV to identify the most nutritious alfalfa variety. For this reason, we have begun selecting varieties based on actual in vitro digestibility, a procedure that accurately predicts the true feeding value of an alfalfa variety. At present, WL is the only alfalfa breeding company using this highly accurate technique for breeding high-quality alfalfa varieties.

HQ (High Quality) alfalfa varieties.
When you see "HQ" added to WL alfalfa variety numbers, you know right away it ranks among the national leaders in alfalfa quality and yields, proven to deliver more milk and beef per acre than other commercial varieties.

WL researchers have discovered that they could improve both yield and quality at the same time by maintaining very high selection standards during the initial breeding process. This stringent selection produced varieties higher in forage quality and yield compared to unselected parental lines. The results in yields are significant according to university researchers. Forage quality also improved — 3 to 12 percent increases in crude protein and 7 to 10 percent increases in RFV. These are the hallmarks of WL HQ varieties.
