摘　　要：The embryo structure of two apomictir lines 296B and SSA-1 has been com-pared in present paper. The apomictic embryo has the same character of lacking (or short) sus-pensor in sorghum,otherwise,the sexual embryo has a long suspensor in the same species. This character as an index of judgement on apomxis was discussed. The same of unsexual embryos in the lack of suspensor suggested that there were some relationships between non-zagotic embryos.The embryo structure of two apomictir lines 296B and SSA-1 has been com-pared in present paper.
