Near‐isogenic populations of frego and normal bract biotypes on each of three varieties of Gassypium hirsutum L. were compared for relative incidence of boll rot in replicated field experiments for three years at several locations in Louisiana. The frego bract biotype of each variety in each year and at each location had significantly less boll rot than its related normal bract strain. The association of frego bract with reduced incidence of boll rot was consistent with the varieties tested at all locations where comparisons were made.
