Abstract:

In order to provide theoretical guidance for haploid breeding of Passion fruit (Passiflora spp.) and other tropical fruits in the future, the technical points and development status of different haploid breeding techniques, such as artificial induced androgenesis, artificial induced parthenogenesis and chromosome doubling, were summarized. The application progress of haploid breeding techniques in the breeding of cereals crops, flowers, forest trees and fruit trees were discussed. Based on the review, it is suggested that the development of haploid breeding technology is beneficial to the establishment of homozygous crop varieties, the advancement of genetic research, the formation of new genotypes, and the acceleration of tropical fruit trees breeding.

Key words: haploid breeding, androgenesis, parthenogenesis, cereals, flowers, forest trees, fruit trees
