Lotus uliginosus was the only species in Loteae previously reported to produce rhizomes. Subsequent research efforts verified the species identity of the rhizomatous collections as L. corniculatus and morphologically and anatomically verified rhizome development. It was determined that the presence of rhizomes in L. corniculatus is controlled by a single, dominant gene. The rhizomatous trait was introgressed into cultivated L. corniculatus that resulted in the release of the cultivar ARS-2620. Rhizomes can be important for increasing the persistence of birdsfoot trefoil where plant and stand longevity are reduced. Stand persistance may increase where rhizomatous plants develop new shoots and roots seasonally replacing dead or diseased plants. This paper summarizes experiences with rhizomatous birdsfoot trefoil since its discovery in 1988. The discussion provides insight into what potential the rhizome trait has for improving persistence, productivity, and adaptation of birdsfoot trefoil, and raises some issues pertinent to getting new technology to the producer. |
