摘要:
“中国春”—长穗偃麦草二体附加系与“中国春”—2C二体附加系杂交,观察到F1代减数分裂过程异常。F1花粉母细胞减数分裂时出现了大量的单价体和一定频率的多价体;在后期Ⅰ和后期Ⅱ均看到大量的染色体断片、染色体桥、落后染色体等异常现象;在F1末期或四分孢子中观察到大量的微核;还出现了细胞质的多极分裂。可能是由于杀配子染色体作用引起的染色体断裂和易位造成的。
Abstract:
By crossing CS- (1- 7) E "with CS- 2C’, We observed the abnormal behaviors of Fi pollen cell meiosis. There were a great of univalent and certain frequency multivalent chromosome appeared in Fi. We also observed that a large number of chromosome fragment, chromosome bridge,laggards etc appeared at anaphase I . anaphase n and a great quantity of micro-nucleus at telophase of F, or tetrad. It appeared cytoplasmic multipolar division in the experiment. Those aberration were probably caused by chromosome splitting and translocation made by gametocidal chromosome.
