| 摘 要： | 以柞蚕纯种"青黄一号"群体中分离出的浅色茧个体为基础材料,以茧白色为表型标记,采用系统分离和定向选择的育种方法,育成了适合二化一放地区(主要为高寒地区)放养的柞蚕大型白茧新品种大白一号。经小区试验和农村生产鉴定,主要经济性状均超过第一对照种扎兰屯1号和第二对照种白茧8344,其中千粒茧重11.68 kg,茧层量1.42 g,平均每把产茧量1 562.50 kg,分别比第一对照种提高18.70%、22.34%和37.27%,比第二对照种提高38.22%、29.41%和53.38%;茧丝长1 248.42 m,解舒丝长744.93 m,分别比第一对照种增长167.21 m和273.31 m,分别比第二对照种增长216.98 m和271.91 m;生丝白度为54.8%,比第二对照种高2.9个百分点。该品种具有茧型大而白、强健好养、高产稳产、茧丝质优良、5龄幼虫能抵御突变的低温(3~8℃)和杂交性能强等特点。
