On June 23, the reporter learned from the Institute of Sericulture of the Provincial Academy of Agricultural Sciences that Xichong sericulture farmers raised the first batch of colored silk cocoons in Nanchong and were sold out at a maximum price of 40 yuan/kg, which means the city's color cocoon technology industry. The beginning of the process. The natural silk products processed from colored silk cocoons are used for clothing and other supplies that are healthy, environmentally friendly, and are not decolorized. It is expected that the traditional silk natural fibers need to be artificially dyed from raw materials, which has the disadvantages of high cost, easy contamination, and fading.

It is understood that the economic traits of the new silkworm varieties No. 19 and No. 24 developed from the Institute of Sericulture have reached the level of practical silkworm cultivars and can distinguish male and female silkworms based on their zebra pattern and color to achieve male and female larval rearing and male and female pupa breeding. To lay the foundation for raising the quality of silk yarn, its breeding technology and practicality rank the leading domestic level. The special silkworm variety Sichuan Silkworm No. 20 with special characteristics for bred breeding has reached the level of practical silkworm cultivars for its economic traits, and can increase the hybridization rate to 100% when producing a new generation of hybrids.

In addition, it uses the obvious difference in moth body color to improve the hybridization rate of silkworm eggs and ranks first in the world. It is the first time that China has successfully cultivated a variety of characteristic silkworm varieties based on the difference in moth color to increase the hybridization rate. The yellow pheasant is female and the white pheasant is male. It uses the male and female pupa to separate the silk and uses the male pupa to produce high-grade raw silk to provide high-quality silk raw materials for high-grade clothing production. The breed is cultivated and participated in the identification, which is the first in the country. In terms of color, the Sericulture Institute also cultivates a variety of colorful color varieties such as red, yellow, pink, flesh, and green.
