|
摘要
Chuanshan × Shushui is a high-grade cocoon filament silkworm variety for spring and autumn rearing bred by Nanchong Silkworm Eggs Farm through systematic breeding method. The characteristics of stock seed and F1 hybrid of silkworm variety Chuanshan × Shushui and their breeding technical points and precautions were introduced in the paper. Laboratory identification and rural breeding results showed that Chuanshan × Shushui was characterized by physical strength, high cocoon weight, good cocoon quality and superior neatness, and the cocoons produced could reel 5A-6A class raw silk. The variety was suitable for breeding in silkworm areas in Sichuan, Yunnan and Shaanxi provinces. The variety was approved by Sichuan silkworm breeding committee in 2005, and more than one million boxes of silkworm eggs have been cumulatively bred in silkworm areas in Sichuan,Yunnan, Shaanxi and Hainan provinces.
