强健性多丝量蚕品种“野三元”的育成(英文)

[Objective] The study aimed to breed eminent mulbery wild silb with hypersilk.[Method] Eminent mulberry wild silkworm basic materials Ye A and Ye B were bred by distant complex crossing of wild mulberry silkworm with strong stress resistance and hypersilkgeneous silkworm,then hybridized with Japanese silkworm strain,the new silkworm variety "Yesanyuan" with healthiness and hypersilkgene was bred.[Ressult]The results of laboratory identification and rural productive test in Jiangsu Province showed that it has excellent feeding habit,strong stress resistance,high yield,excellent silk quality and excellent fecundity.The new silkworm variety "Yesanyuan" had been approved by Silkworm Variety Evaluation Commission of Jiangsu Province in 2008,it is suitable to rear in Yangtze River catchment for Spring and Autumn,North sericultural area for all-year.[Conclusion] The study is helpful for the development of silkworm industry.

家蚕品种野三元耐微量拟除虫菊酯类农药污染新品系的筛选

基于为培育耐农药污染家蚕品种和研究家蚕对农药的耐受性机制提供基础材料的目的,对包括家蚕四元杂交品种野三元中2个含野桑蚕血统的中系亲本野A、野B和2个日系亲本84Y2、784等在内的160份家蚕品种资源,以0.01 mg/L杀灭菊酯添食后进行耐药性筛选,供试家蚕品种中的野B、辐射诱变品种辐7对微量杀灭菊酯具有较强的耐受能力。进一步以0.1～0.3 mg/L杀灭菊酯添食诱导后,自野A、野B中筛选建立了新的耐受性品系野AJ、野BJ,另以辐7为母本,分别以84Y2、784为父本杂交后培育获得新的耐受性品系辐84Y2、辐784。从以上4个新品系中均获得了添食微量杀灭菊酯后幼虫存活率100%的蛾区。4个对微量杀灭菊酯具有较强耐受性的新品系,进一步通过农药诱导选择及系统选择提高和固定其耐受性水平后,可作为耐农药污染新品种的育种材料。
