通过突变体诱捕实验，总共获得了 508 个影响蓝斑鹘自交不亲和性的可能突变体。 这些“突变体”中没有一个包含新的功能不相容等位基因的突变，并且 356 个表现为回复突变体。 一百五十二个突变体是自交亲和的，描述了这些突变体的分析方法，并报告了其中 37 个突变体的研究结果。 十六个是 S 基因座的突变体，包括纯花粉突变体和一个完全突变体； 6 个是 Z 基因座上的纯花粉突变体，16 个是另一个基因座 T 上的突变体。该基因座在指定花粉或花柱的不亲和状态时不提供遗传多样性。 建议了该位点的可能作用。
A total of 508 possible mutants affecting self-incompatibility in Phalaris coerulescens were obtained from a mutant trap experiment. None of these 'mutants', included mutations to a new functional incompatibility allele and 356 behaved as revertants. One hundred and fifty-two of the mutants were self-compatible and the methods of analysis of these mutants are described and the results from studying 37 of them are reported. Sixteen are mutants of the S locus including pollen-only mutants and one complete mutant; six are pollen-only mutants at the Z locus and 16 are mutants at a further locus T. This locus does not act to provide genetic diversity in specifying the incompatibility status of the pollen or style. Possible roles for this locus are suggested.
