Abstract

In Bombyx mori a dominant, autosomal mutation was confirmed to produce loosely constructed, elliptic cocoons, which have a cotton-like texture. The mutant gene was named "flossy" with the symbol Fl after a previous achievement by Takasaki. Genetic analysis applying the genes q and obt as markers mapped the Fl locus to the 32.1 position on the seventh linkage group. The normal individuals segregating from Fl in a cross, using the q gene as a marker, gave tight cocoons with a peanut-like shape. No characteristics except the cocoon size and shape were different between Fl and normal individuals. It was concluded that the Fl gene function was related to the spinning behavior during the cocoon formation.
