The experiment showed that most hybrid stock female moths of Liangguang No. 2 at 25 -28℃ oviposited in the first 5 hours, and egg production declined sharply after 5 hours. 7 · Xiang × Fu · 9 achieved the oviposition peak within 1 hour after casting the moth, the oviposition amount within 5 horns accounted for 92.94% of the total oviposition amount of female moth, that within 9 hours accounted for 96.47%. Fu · 9 × 7 · Xiang achieved the oviposition peak within 2 -4 hours after casting the moth, the oviposition amount within 5 hours accounted for 85.21% of the total oviposition amount of female moth, that within 9 hours accounted for 92.78%. Oviposition regularity of the hybrid silkworm stock moth of Liangguang No. 2 meets the need of dry-hot air treatment of silkworm pebrine-control egg age within 12 hours.展开更多

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 wascharacterized by physical strength, high cocoon weight, good cocoon quality and superior neatness, and the cocoons produced could reel 5A6A classraw silk. The variety was suitable for breeding in silkworm areas in Sichuan, Yunnan and Shaanxi provinces. The variety was approved by Sichuansilkworm 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.展开更多
