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
