QTL-Seq Identifies Extra QTLs and Candidate Genes Controlling High Haploid Induction Rate in Maize [PDF]
PlantsDouble-haploid (DH) technology is a well-established method for speeding up the development of inbred lines in breeding programs. The major loci qhir1 and qhir8 are widely used in marker-assisted selection (MAS) to increase the haploid induction rate ...

Genetic basis of maize maternal haploid induction beyond MATRILINEAL and ZmDMP
Frontiers in Plant Science, 2023 In maize, doubled haploid (DH) lines are created in vivo through crosses with maternal haploid inducers. Their induction ability, usually expressed as haploid induction rate (HIR), is known to be under polygenic control. Although two major genes (MTL and

Genetic dissection of maternal influence on in vivo haploid induction in maize
Crop Journal, 2020 In vivo haploid induction based on maternal haploid inducers is the first step in deriving completely homozygous maize doubled haploid (DH) lines. Haploid induction rate (HIR) is influenced by both pollen parent inducing haploidy and the maternal source ...

Genetic Analysis of Maternal Haploid Inducibility for In Vivo Haploid Induction in Maize
Agriculture, 2022 Doubled haploid (DH) technology based on in vivo haploid induction has gradually become the key technology in modern maize breeding. The ability of maternal germplasm to be induced into haploids, inducibility, varies among genotypes.
