Silk in China

• China is the cradle of the world’s sericulture, and it has a long history of 5000 years.

• As early as two thousand years ago, it was called the “silk country”. Now, China is the largest silk producer and exporter in the world.

Sericulture in Guangdong

• Guangdong Province is one of the major silk-producing and marketing regions in the country.

• Owing to its adequate climatic conditions and to the traditional techniques, the production of silkworm cocoons per hectare stands in the world’s.

• The techniques of mulberry planting and silk producing in the province are comparatively adaptable to tropical and subtropical zones.

Sericulture in SCAU/RSTC

• In Nov. 1982, to promote the sericulture development and technical cooperation among the developing countries,

• UNDP, FAO and the Chinese Government co-sponsored the Regional Sericulture Training Centre for Asia-Pacific (RSTC) in the South China Agricultural University (SCAU),Guangzhou,China.

• With a view to assisting those countries interested in sericulture by training personnel in S & T and management in this field.

Staff in RSTC

• In the Sericulture training center, There are now 14 permanent staffs,and 3 Prof.s, 7 Assoc.Prof. and 4 lectures.

• 8 Ph.D

• 6 Ph.D students,

• 45 MS.C
