The botanical, biological characters, male meiosis and offspring chromosome numbers of a haploid Capsicum annuum L. were observed. There were some differences in botanical and biological characters between the haploid and the diploid. In the haploid, natural chromosome doubling occurred due to unreduced eggs, 0.127 seeds per fruit developed, and all ®ve offspring seedlings were restored to diploidy. At meiotic pachytene, a pseudosynaptic structure occurred. During male meiosis of the haploid, 14.2
