Occurrence of spontaneous larval mutant in the polyvoltine silkworm, Bombyx mori L.
Abstract :A recessive mutation was found during the course of basic stock maintenance in December 2009. Some spontaneous marked mutant larvae (0.20%) were observed in a polyvoltine silkworm race “Pure Mysore” of the mulberry silkworm, Bombyx mori L. The mutant larvae were dark brown body color and characterized by prominent crescent and star spots when compared to normal cream-white larvae. The performance of mutant larvae was inferior to the normal and the comparative performance of mutant x CSR2 and normal x CSR2 has also been discussed
