Sporophyte plants with many gametophytic chromosomes are called haploid plants. These plants can be produced naturally or through in vitro or in vivo induction techniques. Double haploid (DH) can be obtained by doubling the number of haploid chromosomes spontaneously or artificially. They are homozygous, and this homozygosity will be realized in the life cycle of a generation using the DH production system. This production system is used to correct heterosis. Easy to interact with the DH population. DH can be used as parental inbreds of new varieties or self-pollinated plants or cross-pollinated plants. Haploids can be used to isolate mutants, especially if the mutant allele is not diploid. If the haploid is transformed immediately after the chromosome is copied, the plant can be obtained step by step. By combining biotechnological means with conventional methods, the important goal of improving cultivated plants can be achieved in a short time. This article analyzes the various developments in the field of haploid species related to economically important ornamental species.
