Dominant genetic male sterile induced mutant of LaGrue, gene symbol Ms_. In 2003 panicles of 17 previously collected sterile plants were progeny tested. The pooled segregation ratio was 145 fertile:135 sterile plants, a satisfactory fit to a 1:1 ratio for a dominant genetic male sterile. Seeds from the sterile plants were composited for GSOR 4, which should segregate 1 fertile:1 sterile.
