在诱变育种中,既有质量性状突变,也有数量性状突变。在实际工作中,对后者的正确判断比较困难,由于各自的主观性,所取标准的不一,其结果必然各有所异。这不仅影响学术交流,而且会影响选择效果。鉴于此种情况,高泰保等提出了使用增山公式,用计算临界值的方法进行突变频率统计。此法是采用一定的显著水准(a),是求出供试原品种正常变化范围的临界值,以临界值以外出现的个体计为突变,其变异数与观察总个体数的比值定为 In mutagenesis breeding, there are both quality traits and quantity traits. In the actual work, the latter’s correct judgment is more difficult. Due to their subjectivity and different standards, their results will inevitably vary. This not only affects academic exchanges, but also affect the choice effect. In view of this situation, Gao Taibao proposed the use of increasing mountain formula, using the method of calculating the critical value mutation frequency statistics. This method adopts a certain significant level (a), is to find the critical range of the normal variation range of the original test varieties, with the individual outside the critical value as a mutation, the ratio of variation to the total number of observations as
