The "stubble" gene is a good mature plant marker gene. It is simply inherited and expressed on the rachilla, glume, and rachis margin hairs. The effect looks as if a mower had been run over these areas leaving a stubble. This expression can readily be seen in both long haired SS and short haired ss rachilla types. "Stubble" can not be scored easily in certain smooth-awned barleys where most, and sometimes all, the hairs on the glume and rachis margin are missing. In a small F2 population, "stubble" appeared independent of Ss. The gene was found among world collection barleys from Korea and adjacent China. I have developed isogenic lines of "stubble", set up in both long haired SS and short haired ss backgrounds. Seed is available from the Barley Genetic Stock Center, Fort Collins, Colorado 80521, U.S.A.
