2019年9月25日 · DH technology offers the fastest and most efficient route to produce completely homozygous lines for maize breeding programs. It allows the development of homozygous inbred lines in a single year, compared to three to 4 years of inbreeding with the conventional recurrent selfing method, when using off season nurseries.

The established method for maize DH production covered in this review involves in vivo induction of maternal haploids by a male haploid inducer genotype, identification of haploids from diploids at the seed or seedling stage, chromosome doubling of haploid (D 0) seedlings and finally, selfing of fertile D 0 plants. Development of haploid ...

2019年6月10日 · Doubled haploid (DH) breeding based on in vivo haploid induction has led to a new approach for maize breeding 1. All modern haploid inducers used in DH breeding are derived from the haploid...

2023年4月29日 · Doubled-haploid (DH) technology in maize has emerged as a promising tool for accelerating the development of completely homozygous lines in a much shorter time than conventional breeding methods. The breeding cycle is shortened and genetic gain is enhanced using the rapid doubled-haploid line generation method.

2025年3月28日 · In the case of maize, the in vitro-based methods have generally shown to be less effective compared to in vivo-based approaches, particularly the maternal HI system which facilitates the large-scale production of DH lines, rendering this strategy more reliable for integration into breeding programs. Paternal haploid inducers and CENH3-based ...

2020年7月18日 · The development of DH lines in maize involves haploid induction, haploid identification, chromosome doubling, and field sowing for self-pollination of D 0 plants. Different potential methods are used for haploid induction, in-vivo …
