对普通小麦×黑麦杂种F_1～F_6代的减数分裂时期染色体的异常行为、花粉育性和结实率进行了调查。对观察资料进行的统计分析表明:(1)杂种在F_1～F_5代间的减数分裂异常率的差异极显著(P<0.01);(2)减数分裂不同时期的染色体异常率有显著差异(P<0.05);(3)减数分裂异常率与自交代数、花粉育性之间呈强负相关(r=-0.9327;r=-0.9352),花粉育性与结实率之间呈强正相关(r=0.8802)。 The abnormal chromosome behavior, pollen fertility and seed setting rate of meiosis in F1 × F6 generation of common wheat × rye hybrids were investigated. The statistical analysis of the observed data showed that: (1) There was significant difference in the abnormal rates of meiosis between F_1 and F_5 generations (P <0.01); (2) The rates of chromosomal abnormalities in different stages of meiosis were significantly different (P <0.05). (3) There was a strong negative correlation between the abnormal rate of meiosis and selfing algebra and pollen fertility (r = -0.9327; r = -0.9352) Positive correlation (r = 0.8802).
