0PI 634019N56Melilotus officinalis (L.) Lam. Nebraska, United StatesNC7FIELD2003DEVELOPEDBreeding materialThe finestem trait is conditioned by a homozygous recessive gene that gives rise to a hay-type sweetclover in which fineness of stem and leafiness are very pronounced. It is found in a strain of Melilotus alba but not in M. officinalis which is the predominant species grown in the Great Plains. The finestem gene was transferred from M. alba to M. officinalis by making an interspecific cross using M. officinalis lines as the female parent that were derived from the large-seeded introduction PI 178985. Although this line was derived after two additional backcrosses to M. officinalis and is homozygous for the finestem trait and low coumarin content, it does not have the large seed size of the M. officinalis parent and seed abortion resulting from the interspecific cross is still a problem in many plants. Therefore, some additional backcrosses to superior large-seeded M. officinalis lines are needed followed by selection for finestem, low coumarin content, large seed size and yellow flowers in the selfed progeny.1649718PI 634019
