三对家蚕新品“显身手” 将对我国蚕桑产业发挥重要推动作用
2017-09-11 07:37:43 中国经济网
在日前召开的江苏省桑蚕品种审定会议上,由中国农业科学院蚕业研究所家蚕育种专家吴阳春副研究员主持培育的“野三元(抗)”“苏超2号”和“苏豪×钟晔(抗)”3对家蚕新品种通过了专家评议审定。
其中,“野三元(抗)”是根据江苏省蚕桑生产对抗血液型脓病和耐农药污染蚕品种的紧迫需求,以2008年育成的秋用蚕品种“野三元”为基础,围绕家蚕耐微量菊酯类农药和抗血液型脓病等关键性状,筛选培育出耐微量菊酯类农药兼抗血液型脓病的耐粗食高产优质蚕品种。经规模生产试点,其抗血液型脓病、耐粗食等特性多次得到验证,已对粮桑间作蚕区安全生产发挥出重要保障作用。
“苏超2号”是根据我国茧丝绸行业对优质生丝原料的渴求,利用三眠蚕丝质优的特性,与强健性多丝量蚕品种进行复合杂交选育,加强眠性、超优、抗病、高温多湿抗逆性筛选,培育出的能适宜江苏等省6月至8月续春、夏季、早秋季饲养的高品位生丝抗性蚕品种。该品种在眠性与茧丝质等筛选技术方法上有重大突破,经规模生产试点,已开始规模生产出“超6A”级生丝原料,具有开发高附加值丝绸精品的广阔市场前景。
“苏豪×钟晔(抗)”是中、日合作育成的春用多丝量蚕品种,“苏豪×钟晔”在保持高产、优质、易繁的基础上,杂交导入抗血液型脓病基因性状,筛选培育出抗血液型脓病的多丝量蚕品种,该品种在抗血液型脓病与多丝量保持的筛选技术方面获得重要突破,经规模生产试点,抗血液型脓病及高产优质特性极其显著,可以满足江苏等省春季规模推广应用。
据悉,以上3对新蚕品种审定通过后,可在江苏等省开始大规模推广应用,将对我国茧丝绸行业品牌创建、优质茧基地建设、“一带一路”蚕桑合作等发挥重要的推动作用。(经济日报记者 常 理)
