Book Description

The road for silk production passes through many stages; namely mulberry cultivation, silkworm breeding, and textile production. Each stage comprises many steps which needs professional in various fields, such as agriculture, biotechnology, and textile chemists and technologists.

The term sericulture covers the stages cultivation of mulberry, silkworm rearing and post cocoon activities leading to production of silk yarn. Sericulture offers lucrative employment, economic growth and upgrading the quality of life to the people in rural zones and consequently it plays an important role in anti-poverty programs. Hence several developing nations like China, India, Brazil, Thailand, Vietnam, Indonesia, Egypt, Iran, Sri Lanka, Philippines, Bangladesh, Nepal, Myanmar, Turkey, Papua New Guinea, Mexico, Uzbekistan and some of the African and Latin American countries have taken up sericulture to provide employment to the people in rural area.

The current annual global silk production ranges between 70,000 to 90,000 M.T. and the demand for silk is increasing by 5% annually. With the increase in population and demand for fashionable clothing items due to fast changing fashion designs in developed countries, the demand for silk is bound to increase even more. For increasing the silk production, we require highly productive mulberry varieties and silkworm races and silkworm races tolerant to adverse climatic conditions and diseases which can come mainly from the sericultural germplasm resources and also from the wild relatives of Bombyx available in the natural habitats.

Furthermore, this work highlights the efforts exerted to overcome some problems regarding in vivo and in vitro propagation of mulberry trees, silkworm rearing, post cocoon, and textile technologists leading to economically feasible semi-mass production of silk.
