Backcross and F 2 analysis in alfalfa, MedicagO sativa L., showed that the character stippled leaf was probably controlled by a single recessive gene inherited tetrasomically. The F 1 , F 2 and S 1 progeny were evaluated for the degree of stippling and incidence of mutation. The gene appears to be influenced by mutation and/or modifiers, as evidenced by leaf sectors with very little chlorophyll on plants that normally show a slight amount of chlorotic stippling. The stippling character can be detected in the cotyledon stage of the progeny as very small, round, lightly colored areas. The symbol stp is proposed for this gene.
