Abstract:: Taking the root-tips of Hippeastrum reticulatum var.striatifolium as test materials，using the conventional crushing method to prepare the slice specimens of chromosomes and its karyotype was analyzed.The results showed that the chromosome numbers of Hippeastrum reticulatum var.striatifolium was 2n=22，karyotype formula was K(2n)=2x=8m+6sm+8st，and its As.K% was 69.96%.The chromosome karyotype of Hippeastrum reticulatum var.striatifolium was Type 3B.
