摘    要:对组培条件下秋水仙素诱变的东方百合四倍体及2 n雌配子杂种后代进行了RAPD分析.结果表明:东方百合四倍体诱导过程中,少数植株除了染色体数目加倍以外,还存在DNA序列的改变;2 n雌配子杂种后代RAPD分析表现出丰富的遗传多样性,少数植株RAPD分析差异巨大,特别是T8无性后代存在较大的性状差异,个别植株经RAPD分析与其他单株存在较大的差异.

关 键 词:东方百合 2 n雌配子 多倍体 RAPD

Abstract:RAPD analysis was made of the colchicine - induced tetraploids of Lilium oriental and the hybrid offspring of its 2 n female gametes. The results showed that DNA sequences changed during polyploidization in a few plants besides the doubling of chromosomes. Abundant genetic diversities were observed in the 2 n female gamete offspring. Substantial differences were observed in the asexually propagated offspring of T8 in their characters. Some individuals were shown to be considerably different from others in the RAPD analysis.
Keywords:Lilium oriental    2 n female gamete   polyploid    RAPD
