柞蚕黑蛾新品种选育及杂交组合筛选

Screening of Hybrid Combination and Selection of New Variety of Tussah Black Moth

柞蚕黑蛾新品种选育,以杂交优势强、亲缘关系较远、稳产、高产为目标。以黑蛾做为表型标记,进行个体、区间选择,兼顾各项经济指标的平衡。经过3年6代的选育,形成了目的性状能够稳定遗传的柞蚕生物群体。同时筛选出了与吉柞882、选大二号、L7698H等品种的杂交组合,增产幅度达22.61%~38.56%。

The selection and production of Tussah black moth new varieties aims at selecting superior hybrid varieties with far genetic relationship,stable production and high yield.Take black moth as the phenotype mark,selecting the varieties among individuals and groups,simultaneously balancing the economic indicators.After 3 to 6 years of selection,a community of Tussah with stable genes was formed.At the same time,Jizha 882,Xuanda II,L7698H were screening out,with a production increase rate of 22.61% to 38.56%.
