Induction of Haploids

1986
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 ...

Haploid induction in allotetraploid tobacco using DMPs mutation

Planta, 2022
dmp1dmp2dmp3 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

Discovery of Sorghum Haploid Induction System

2019
Sorghum 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

In Vivo Haploid Induction in Maize: Comparison of Different Testing Regimes for Measuring Haploid Induction Rates

Crop Science, 2016
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

Mutation of ZmDMP enhances haploid induction in maize

Nature Plants, 2019
Doubled 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.

Induction and Growth of Androgenic Haploids

1987
Publisher 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.

In Vivo Haploid Induction in Maize: Identification of Haploid Seeds by Their Oil Content

Crop Science, 2014
ABSTRACTIn 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

Recent Advances in Engineering of In Vivo Haploid Induction Systems

2023
Doubled haploid (DH) technology is an important approach to accelerate genetic gain via a shortened breeding cycle, which relies on the ability to generate haploid cells that develop into haploids or doubled haploid embryos and plants. Both in vitro and in vivo (in seed) methods can be used for haploid production.

Induction of Haploid Embryos in Datura metel by Anther Culture

2021
Microspores, with a haploid number of chromosomes, are destined to produce the male gametophyte, which hosts the male gametes that fertilize the female egg cell. During microsporogenesis, a particular stage of development is amenable to be switched to undergo embryogenesis and developed into a haploid plant.
