In vivo haploid induction in maize
Theoretical and Applied Genetics, 2002Two haploid-inducing lines, MHI and M741H, were used for the production of maternal haploids. Haploids were obtained from all maternal genotypes involved in the experiment, including dent, flint and flintxdent maize. The maternal genotype had a significant influence on the frequency of haploids obtained. The frequency ranged from 2.7% to 8.0%.

In vivo maternal haploid induction system in cotton
Plant Physiology, 2023The ghdmp mutant of cotton, generated through the CRISPR system, exhibits a haploid induction rate of 1.06% in F1 progeny as the haploid inducer line.

The application of tissue culture for the propagation and improvement of trees can be quite varied in both approach and technique. From previous reviews (Abbott 1977, 1978, Bonga 1977, 1980, Sommer and Brown 1979, Karnosky 1981), it is apparent that most of the work achieved up to now in this field has been devoted to the induction of organogenesis or ...

Discovery of Sorghum Haploid Induction System
2019Sorghum is the fifth most important cereal grain crop after corn, wheat, rice, and pearl millet in the world. Conventional sorghum breeding relies on multiple generations of self-pollination to achieve the adequate levels of homozygosity for hybrid evaluation, which adds several years and great cost to the breeding process. As in maize, doubled haploid

The doubled‐haploid (DH) technology, based on in vivo induction of haploid seeds by pollen from inducer genotypes, has become routine in maize (Zea mays L.) breeding. De novo and maintenance breeding of inducers requires measuring the haploid induction rate (HIR) of numerous plants. We compared five testing regimes in combination with three inducers to

Haploid induction in allotetraploid tobacco using DMPs mutation
Planta, 2022dmp1dmp2dmp3 mutants created by CRISPR/Cas9 could trigger maternal haploids in the allotetraploid model plant Nicotiana tabacum L. Double haploid (DH) technology is becoming increasingly important because it can significantly accelerate the breeding process. Haploid induction plays a fundamental role in the production of DH lines. Haploid induction has

Induction and Growth of Androgenic Haploids
1987Publisher Summary Several factors controlling induction and maturation of embryogenic pollen, embryogenesis proper, and regeneration of embryos/calli into whole plants in certain species, belonging to the Solanaceae, Gramineae, and Cruciferae are discussed.

Mutation of ZmDMP enhances haploid induction in maize
Nature Plants, 2019Doubled haploid (DH) breeding based on in vivo haploid induction has led to a new approach for maize breeding1. All modern haploid inducers used in DH breeding are derived from the haploid inducer line Stock6. Two key quantitative trait loci, qhir1 and qhir8, lead to high-frequency haploid induction2.

In Vivo Haploid Induction in Maize: Identification of Haploid Seeds by Their Oil Content
Crop Science, 2014ABSTRACTIn vivo haploid induction has become a routine tool for rapid line development in maize (Zea mays L.). However, distinguishing haploid (H) from diploid crossing (C) seeds is problematic for many germplasms due to poor expression or suppression of the currently‐used R1‐nj embryo marker. We examined a new approach for sorting H and C seeds on the
