家蚕春用品种菁松·皓月的复壮系比较试验

Comparison Experiment of the Rejuvenation Lines of Jinshong and Haoyue for Spring Rearing:

对春用蚕品种菁松、皓月的复壮系与现行生产上应用的生产系进行了生产性能的比较试验。结果表明,与各品系对应的生产系相比,复壮系的龄期经过稍有缩短,生命率略高,全茧量、茧层量、种茧选留率、良卵量与良卵率均有较大提高,达到显著水平以上,说明复壮后的菁松、皓月从孵化到制种各阶段的生产性能优于现行生产应用的生产系,有推广应用价值。

A Experiment was carried out to compared the comprehensive productivity of the rejuvenation lines and the present commercial lines of Jinshong, Haoyue for spring season rearing.Results showed that the young larva stage was a little shorter and the survival rate was a little higher than the present commercial lines, and the cocoon weight, cocoon shell weight, the rate of qualified seed cocoon, good egg number and the percentage of good eggs of the rejuvenation lines were improved significantly compared with teh present commercial lines.It was suggested that the productivity compared with the present commercial lines.It was suggested that the productiovity of rejuvenated Jinshongh and Haoyue were better than the commerical lines during the different stages from hatching to egg produced.
