柞蚕多丝量品种宛黄一号、宛黄二号的选育

Breeding of Tussah Silk Cultivars Wanhuang 1 and Wanhuang 2

通过多年系统选育的方法,对柞蚕遗传性较强的茧层率性状进行连续有目的地认真选择,培育出柞蚕多丝量品种宛黄一号、宛黄二号。这2个品种健康好养,抗病性、抗逆性好,千克卵收茧量平均达380 kg以上,千粒质量10 kg以上,茧层率连年达16%以上,分别比河南省柞蚕现行品种三三高出9.5%,18%,46%,目前在生产上发挥着巨大作用。

With decades efforts and the methods of systematic breeding, the genetic of tussah cocoon layer ratio were selected carefully for many years, tussah silk varieties Wanhuang 1 and Wanhuang 2 are developed. The two varieties are of good health, disease resis- tance and stress resistance, the yeild of egg cocoon per kg has reached above the average yield of 380 kg, thousand eggs weight is more than 10 kg, and cocoon layer ratio more than 16% were set successively, respectively 9.5%, 18%, 46% higher compared to Henan tussah best varietie Sansan. At present, they two play a great role in production.
