Abstract: Anthers with the filament of lily (Lilium davidii var. Willmottiae (Wilson) Roffill) were cultured on modified MS medium. Supplemented with different concentrations and compatible ratios of growth hormones (Z 2 mg/L,or 2,4-D 2 mg/L + KT 2mg/L, or 2,4-D 4mg/L+ 6 BA 2 mg/L). At this time the pollen grains in the anthers were at the late uninueleate stage. Anther cultures were incubated at 25—27 ℃, and illuminated with daylight of about 800–1200 lx. After 30 days, the calli or embryoids were produced from anthers. The frequency of the calli or embryoids induction was 8.89%. After transfer eventually to the differentiation medium, these calli or embryoids developed into plantlets in 70 days. Among the root tips of regenerated plantlets haploid, diploid and aneuploid cells were found, but the haploid cells were produced in about 86.4% of the root tips. It is quite evident that haploid plantlets are derived from the pollen grains.
