碱草核型分析及其三属杂种观察

对碱草的核型以及中５×碱草的Ｆ２植株花粉母细胞的染色体数目和减数分裂情况进行研究，结果表明，这个三属远缘杂交组合的Ｆ２群体中有一部分单株是真杂种。

The Karyotype of Chinese Wildrye and the Genetic Aalysis on Trigeneric Hybrid

The karyotype of chinese wildrye and the number of chromosome and the meiosis condition of the pollen mother cell of the F2 plants which derived from the cross Zhong-5×Chinese wildrye were studied. The result showed that a few of plants deriving from the F2 population of the distant cross of the three genera may be the real hybrid.
