摘  要:
以新引1号东方山羊豆Galegaorientalis cv.Xinyin No.1)为试验材料,根尖染色体进行常规制片分析和利用HBSG流程对其染色体进行C-分带研究,结果表明,新引1号东方山羊豆体细胞染色体为16条,染色体核型公式为2n=2x=16=16m,都为中部着丝粒或近中部着丝粒,确认新引1号的标准C-分带带型为2n=16=10C+4CI+2T。根据Stebbins分类原则属于较为对称性核型(1B)。

摘  要:
The karyotype and C-band of Galega orientalis cv.Xinyin No.1 were studied.The results showed that the karyotype was 2n=2x=16=16m.All the chromosomes were median and submedian centromeric.The C-banding analysis was conducted with HBSG method and the result showed that the C-banding karyotype is 2n=16=10C+4CI++2T.The karyotype was belonged to 1B type based on Stebbins classification system.
