Özet
The discovery of haploids in plants led plant breeders to help to produce double haploids. The chromosome numbers of double haploids are different from haploids. This technique shortens the time to produce homozygous plants as compared to the conventional breeding method. After doubling the chromosome, it produces two identical homologous chromosomes. This helps to achieve homozygosity of crop up to one generation early as compared to conventional breeding. Once an interesting gene combination is achieved through conventional breeding; further mixing of genes is considered a real challenge. The production of double haploids is dependent on haploid inducer lines. The current breakthroughs of molecular actors triggering induction of haploid in plants have an important role of processes related to the development of gamete, interactions, and stability of the genome. These findings allowed translation of induction of haploid, and genome editing technologies can be helpful to produce haploid inducer lines. These recent discoveries can be helpful for improved breeding strategies. Besides that, it also provides deeper information regarding sexual reproduction in plants. In this chapter, we discussed how we can produce haploid inducer lines and with the help of new biotechnological tools to produce double haploid plants. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
