【摘要】 通过普通小麦幼穗组织离体培养，建立起了两个小麦体细胞无性系。以禾谷镰刀菌的粗毒素为选择剂，应用多步筛选方法，从两个体细胞无性系中分离出了ＷＴｓｃｖ－１，ＷＴｓｃｖ－２，ＷＴｓｃｖ－３，ＷＴｃｖ－４和丰ｓｃｖ－１５个抗性变异细胞系，从三个抗性变异细胞系中获得了再生植株。５个变异细胞系对镰刀菌毒素有较强的抗性。更多还原

【Abstract】 Two somatic cell clones , designated as W 1 and W 2 have been established from wheat immature inflorescences in vitro. Five Fusarium graminearum toxin resistance lines, designeted as WTscv 1 , WTscv 2 , WTscv 3 , WTscv 4 and Fscv 1 have been isolated by using muti step selection system under the crude toxin stress condition from two somatic cell clones. Plantlets had been regenerated from three crude toxin resistance cell lines. The resistance of these variant line against the crude toxin of Fusarium graminearum is stonger than that of the parent.更多还原
