One hundred random clones from 'Cherokee' alfalfa (Mediccigo sativa L.) were evaluated by self-(S,), topcross-, and clonal-progeny tests. Clonal progenies were most effective, topcross progenies moderately effective, and S, progenies the least effective in predicting first-cross yield. Forage yield was mostly independent of self-fertility. Nine clones were selected for yielding ability based on the progeny tests. The nine clones, their S, families, the diallel set of single-cross families from the nine clones, and the Syn 1 and Syn 2 generations of 10 synthetic varieties from the nine clones were evaluated. The best single-cross family yielded 150 7c; the best Syn …
