Abstract

Two sweetclover [Melilotus officinalis (L.) Lam.] germplasms, N28 (Reg. no. GP-2, PI 552553) and N29 (Reg. no. GP-3, PI 552554), are improved biennial, yellow-flowered strains selected for low coumarin content (or, more accurately, for low content of o-hydroxycinnamic acid β-D-glucoside; [1]) and for resistance to the sweetclover aphid (Therioaphis riehmi Bomer). N28 and N29 were developed cooperatively by the USDA-ARS and the Nebraska Agricultural Research Division and were released in February 1991.
