The fundamental aim of silkworm breeding is to get robust and sturdy silkworm larvae for easy rearing and production of best cocoons in quality and quantity for a high yielding cocoon crop. The morphological characterization among domesticated insects like silkworm (Bombyx mori L.) is an important aspect for selection of suitable parents for breeding programme. Sericulture in India is practiced under varied agro-climatic conditions adopting different package of practices to suit different regions and seasons, besides being conserved and utilized for evolving high yielding breeds/hybrids. Characterization is of immense importance for isolating duplicates and it also identifies the genetically potential parents for breeding programmes. Many numbers of geographical races of Silkworm, Bombyx mori are being reared in many geographical areas of world and inbred lines. Generally, cocoon commercial characters are used to identify silkworm verities and selection of parental strains. Keeping in view the objectives of the paper the available literature was reviewed for phenotypic and quantitative characterization.
