雌雄异株工业大麻杂交育种试验研究

Study on Hybrid Breeding of Dioecious Industrial Hemp

在杂交育种过程中,杂交试验方法多种多样,随着近年来工业大麻杂交育种的发展,育种家常用的试验方法多为使用杂交棚或套白布罩进行隔离、整株自然或人工授粉。以黑龙江省4个工业大麻主栽品种龙大麻5号、龙大麻3号、庆大麻1号、龙大麻1号为试验材料,开展工业大麻套袋杂交育种试验。在玉米套袋杂交育种基础上进行改良,开展雌雄异株工业大麻套袋杂交育种试验,人工授粉杂交结束后测定杂交结实率,结果证实该试验方法行之有效,可用于亲本数量稀少情况下的种质资源扩充及选择。

Hybrid test methods varied in the process of cross breeding.With the development of industrial hemp cross breeding in recent years,the commonly used test method is to use more hybrid breeders shed or set of white cloth cover for isolation,natural or artificial pollination.With four industrial hemps Longdama 5,Longdama 3,Qingdama 1 and Longdama 1 as the test materials,bagged cross breeding test of dioecious industrial hemps was carried out.The experimental method was improved on the basis of maize bagging crossbreeding,and the bagging crossbreeding experiment of dioecious Chinese hemp was carried out.After artificial pollination,the seed setting rate was measured.The experimental results proved that this method was effective and could be used to expand and select germplasm resources in the case of few parents.
