黑龙江省纤维亚麻诱变育种始于60年代初,先是开展钴60γ—射线、热中子和快中子进行种子照射,70年代开始辐射与杂交相结合育种,80年代用钴60γ—射线进行亚麻活体照射,先后获得一批优良突变系,育成黑亚四号、六号两个优良品种,并在辐射材料的选择、适宜引变剂量 Heilongjiang Province, fiber flax mutagenesis breeding began in the early 60s, first to carry out cobalt 60γ-ray, thermal neutron and fast neutron seed irradiation, radiation and hybridization began in the seventies combined breeding, 80 60Co γ-ray flax In vivo irradiation, a number of excellent mutant strains have been successively obtained, bred into two fine varieties of Heiya IV and VI, and the choice of radiation materials, suitable for variable dose
