摘　　要：通过田间试验,对几个利用温敏雄性不育亚麻雄性不育系配制的杂交种的产量表现及不育株率和不育株率对产量的影响进行了分析。结果表明,亚麻杂交种和常规品种相比,具有显著产量优势。不育株和正常可育株相比,产量性状明显偏低,因此,杂交种不育株率的高低将影响杂交种的产量。The yields of the Several two-line hybrids and traits between normal plant and male sterility plant of F1 generation of hybrid flax were investigated. The results showed that the two-line flax hybrid had significantly higher seed yield. Differences of boll number per plant, seed number per boll and seed weight per plant between normal plant and male sterility plant of FI generation were highly significant, yield of sterility plant was lower, which result showed that the male sterility plant of hybrid have a negative effect on the seed yield.
