Observations of the F1, F2, and F3 progenies of crosses between normal annual Melilotus alba Desr. and three mutants, folded leaflet, elongated stem, and short-petiole dwarf, indicate that each of the mutant characters is controlled by a single recessive gene. Proposed symbols for the three mutant genes are f, el, and dsp, respectively. In limited tests for linkage, el appeared to be linked (12% recombination) to a gene for multifoliolate leaves (Mf). No linkage was detected between f and Mf, cu (low o-hydroxycinnamic acid), or b (low β-glucosidase activity).
