- Cultivated alfalfa (Medicago sativa L.) is a major forage legume grown extensively worldwide. This perennial species has a tetraploid (2n = 4x = 32) genome which displays tetrasomic inheritance and its populations are extremely polymorphic due to a high degree of outcrossing. Superior tolerance to environmental stress and decline in stem digestibility during plant development are major issues for alfalfa breeding programs.
- Insufficient tolerance to subfreezing temperatures reduces long term persistence of alfalfa in northern countries and is a source of major costs associated with stands reestablishment and the need to buy forage outside the farm.Lignin deposition in maturing stems significantly interferes with the release of simple sugars from the cellulose and hemi-cellulose fiber fraction and causes a significant decline in feed value.
- Alfalfa holds the distinction of being the oldest forage crop for which we have a name, yet the etymology of the word is uncertain. It may have arisen from modifications of the Persian aspo-asti (horse fodder), the Arabic al-fasfasa or the Kashmiri ashwa-bal (both meaning horse power). Some have speculated that the name most commonly used in Europe, "lucerne," may derive from the Persian word läjwärd for lapis lazuli, the ultramarine blue mineral lazurite, in reference to the blue flowers of Medicago sativa—one of the two species, with M. falcata, known as alfalfa.  .
