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
针对农村蚕桑生产中血液型脓病危害严重的现状,利用抗病种质资源,通过杂交和回交的方法选育出抗血液型脓病的家蚕四元杂交新品种明湖春江。国家和浙江省实验室鉴定结果显示,明湖春江4龄起蚕虫蛹率、出丝率与秋丰×白玉(对照)相仿,...针对农村蚕桑生产中血液型脓病危害严重的现状,利用抗病种质资源,通过杂交和回交的方法选育出抗血液型脓病的家蚕四元杂交新品种明湖春江。国家和浙江省实验室鉴定结果显示,明湖春江4龄起蚕虫蛹率、出丝率与秋丰×白玉(对照)相仿,万蚕产茧量分别比对照提高8.78%、11.25%;解舒丝长达900 m以上,超过对照;洁净高于94分。国家和浙江省农村生产试验的张种产茧量分别比对照提高15.36%、11.06%,健蛹率与对照相仿。抗血液型脓病检测结果表明,家蚕核型多角体病毒(Bombyx mori nucleopolyhedrosis,BmNPV)对明湖春江的LC_(50)值为3.102×10^(8)mL^(-1),对照为2.085×10^(6)mL^(-1)。新品种于2022年5月通过浙江省主要农作物品种审定委员会审定,并于2022年12月通过国家畜禽遗传资源委员会审定。该品种适合在长江流域和黄河流域秋期饲养。展开更多
