摘　　要：１９８９～１９９２年以禾谷镰刀菌Ｆ＿４号菌种的粗毒素为选择剂，采用多步正筛选法，从来源于同一个花粉胚的单倍体细胞无性系Ｈ＿（１６）中筛选出三个抗性细胞系──Ｈ，Ｈ和Ｈ。与亲本系相比，这些变异系具有较强的抗毒素毒害能力，在继代培养６次后，其抗性性状表现稳定。Three Fusarium graminearum toxin-resistant variants,designated asH,H and H,have been selected from a wheat haploid clone H_(16) with the use of thecrude toxin of Fusariunz graminearum No. 4 and the multi-step selection system. Theresistance ability of variant lines against the crude toxin of Fusarium graminearum isstronger than that of the parent and the resistance property of variant lines keeps stableafter the variant lines have been cuLtured in a medium lacking the crude toxin for 6 gen-erations.
