2015年国家桑蚕品种试验安徽点实验室鉴定报告
|
摘要
为了鉴定、评价新选育蚕品种在安徽省的适应性、稳产性、丰产性、抗逆性、茧丝质及其他重要特征特性,按照《国家桑蚕品种试验实验室鉴定实施方案》的要求,于2015年春、秋蚕期对10对蚕品种进行实验室鉴定。结果表明:参鉴蚕品种试验成绩各有高低,客观反映了各参鉴品种在安徽实验室鉴定点的饲养情况及性状表现。与对照蚕品种秋丰×白玉、9·芙×7·湘相比,参鉴的7对蚕品种春秋蚕期的茧层率高0.64%~13.04%,多数参鉴蚕品种的万蚕收茧量高。秋蚕期,5对品种的茧丝长均优于对照蚕品种。但参鉴品种虫蛹率均低于对照蚕品种9·芙×7·湘。
High yield,stable yield,adaptability,resistance,quality of cocoon and silk and other specific characteristics of new silkworm varieties were investigated in Anhui Province. Laboratory identification of 10 silkworm varieties is going strictly according to the standard of National Method for silkworm,Bombyx mori Variety Test in laboratory identification in spring and autumn rearing period in 2015. The results showed that there were differences in the test,and the results reflected feeding condition and the performance of the identification point of each reference in Anhui. Compared with Qiufeng × Baiyu and 9·Fu × 7·Xiang,cocoon layer ratio of 7 silkworm varieties increased by 0. 64%-13. 04%. Yield of cocoon crop per 10 000 larvae for most of identification varieties was high. In autumn rearing period,length of cocoon filament of 5 silkworm varieties was better than that of control,but larva-pupa rate of test varieties was lower than that of 9·Fu × 7·Xiang.
