摘　　要：试验以ＩＥ８５１５－２８（７７（２）春品种的胚培后代）１４个早熟株系的ＩＥ５代植株为材料，观察植株后代花粉粒育性．结果表明．小麦未熟胚离体培养后所产生的后代，结实均表现正常，但在成熟花粉粒育性观察中发现空瘪、小型以及多萌发孔等畸形花粉粒．而且不同株系各种异常花粉粒所占比例不同．说明胚培无性系后代遗传基础受到深刻影响，包括小孢子形成和发育的全过程．The IE5 generation of 14 lines early in maturity derived from embryo culture progeny IE 8515-28 of cultivar 77(2)-Spring were used as the materials for pollen fertility study. The results showed that the performance of seed-setting in progenics from immature embryo culture in vitro was normal but various types of abnormal pollen were found, including the empties,the smallest and multi-germination poles in different percentages.It indicated that the genetic base of the somaclonal progeny from embryo culture in vitro was significantly influenced and involved the formation of small spores.
