摘要
初步对 2 81个家蚕品种资源进行了抗质型多角体病毒比较试验。 2 81个蚕品种中 ,抗性品种占12 4 5 % ,较抗性品种占 32 74 % ,较感性品种占 33 81% ,感性品种占 2 1 0 0 %。不同品种间抵抗性差异较大 ,最高达到千倍以上。不同地理系统间抵抗性差异数百倍 ,其强弱依次为热带多化性品种 >中系二化种 >日系一化种 >中系一化种 >日系二化种 >
silkworm races were used to test their resistibility to Bombyx mori cytoplasmic polyhedrosis virus(BmCPV). The results show that the resistant races, the relative resistant races, the relative susceptible races and the susceptible account for 12 45%, 32 74%, 33 81% and 21 00% respectively. Notable difference exists in different races, the highest difference reached more than 1 000 times. The difference of resistibility in different strains is about hundreds times, and its order is:Tropic polyvoltine>Chinese bivoltine>Japanese monovoltine>Chinese monovoltine>Japanese bivoltine>European monovoltine.
