摘要： 以6个同源四倍体高粱品系及其与约翰逊草的种间杂种为材料，对两种间细胞学特性的相关性进行了分析。杂种F1后期Ⅰ、后期Ⅱ减数分裂的不规则性受到亲本高粱细胞学不规则性的影响，杂种F1减数分裂规则性与约翰逊草相似。

Abstract: The relationship of cytogenetic character of interspecific hybrids between 6 autotetraploid sorghum lines and Johnsongrass was analysed.The irregularity in meiotic AⅠ,AⅡ of F1 hybrids was effected by that of parent sorghum,and the regularity was similar to that of Johnsongrass.
