试验用链霉素等 5种抗生素对油用亚麻品种 (系 )陇亚 8号、94 1 0、90 3 3的种子进行浸泡处理 ,诱导雄性不育突变体 ,对获得的不育材料进行特征特性观察以及育性遗传分析。研究结果表明 :( 1 ) 5种抗生素均能诱发油用亚麻雄性不育突变 ,诱变剂种类、处理浓度及油用亚麻品种是影响诱变效果的重要因素。 ( 2 ) 94 1 0诱变处理获得 3株不育株 ,其 M2 表现育性分离 ,诱变不育性可以遗传 Experiments with streptomycin and other five kinds of antibiotics on the oil with flax varieties (lines) Longya 8, 94 1 0,90 3 3 seeds were soaked treatment to induce male sterile mutants, the characteristics of the sterile material obtained Characterization and Fertility Genetic Analysis. The results showed that: (1) All five kinds of antibiotics can induce the male sterility mutation of linseed oil. The types of mutagen, the concentration of treatment and the flax varieties for oil are the important factors that affect the mutagenic effect. (2) 94 1 0 mutagenesis treatment to obtain three sterile plants, the M2 performance of fertility separation, mutagenicity can be inherited
