The study was conducted to get basic information for haploid production of Petunia hybrida through anther culture by investigating several factors, namely anther stage, culture medium, cold treatment, and genotypes. The results are summarized as follows; Four genotypes of Petunia hybrida were used in a study of anther culture. Plants of each genotype were grown in controlled environments at $20-30^{\circ}C$ with a 16h photoperiod. Equal numbers were harvested from each genotype. The anthers were taken from buds which had received the 14 days' cold treatment at $4^{\circ}C$. Anthers were dissected out aseptically and plated on 1/2 strength MS agar medium containing 5.0mg/${\ell}$ 6-Benzylaminopurine(BAP). Four weeks after culture, light green callus was formed. From these calli, plantlets were regenerated on MS medium containing 2.0mg/${\ell}$ 2-isopentenyl adenine(2ip) after 3 weeks.
