Development of Specific Molecular and Phenotypic Marker-Based Haploid Inducers in Rice

Agronomy, 2023
Doubled haploid (DH) technology is an efficient strategy for producing completely homozygous lines for breeding programs. Mutations in the MATRILINEAL (MTL) phospholipase trigger intraspecific haploid induction in cereals.

Development of In Vivo Haploid Inducer Lines for Screening Haploid Immature Embryos in Maize

Plants, 2020
Doubled haploid technology is widely applied in maize. The haploid inducer lines play critical roles in doubled haploid breeding. We report the development of specialized haploid inducer lines that enhance the purple pigmentation of crossing immature ...

Influential factors and transcriptome analyses of immature diploid embryo anthocyanin accumulation in maize

BMC Plant Biology, 2022
Background Anthocyanins are widely applied as a marker for haploid identification after haploid induction in maize. However, the factors affecting anthocyanin biosynthesis in immature embryos and the genes regulating this process remain unclear.

Identification of haploid and diploid maize seeds using hybrid transformer model

Multimedia Systems, 2023
Increasingly, more effective breeding techniques for new variations are preferred due to population growth and climatic change, particularly the accurate identification of the target variety. Maize haploid breeding technology, which can shorten the reproductive period and improve germplasm, has become the key to new maize breeding.

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 ...

Identification of in vivo induced maternal haploids in maize using seedling traits [PDF]

Euphytica, 2017
AbstractIn vivo haploid induction in high frequency followed by efficient identification of haploids are important components of deriving completely homozygous doubled haploid (DH) lines in maize. Several genetic marker systems were proposed and/or used for identification of in vivo maternal haploids in maize, such as R1-nj (Navajo), high oil, red root

Production and identification of doubled haploids in tropical maize

Genetics and Molecular Research, 2013
The production of maize doubled haploid (DH) lines is a technique commonly used by private companies, but not by Brazilian public institutions. Research on this technique is essential to develop and improve the production of DH lines grown under tropical conditions. We assessed the ability of a gynogenetic haploid inducer system to induce haploids in a

Identification of haploid maize by flow cytometry, morphological and molecular markers [PDF]

Ciência e Agrotecnologia, 2013
The development of homozygous breeding lines in maize may be accelerated through the use of haploids. Thus, the obtaining and prior identification of haploids generated by the haploid inducer lines is an important factor. The purpose of this study was to identify haploids by flow cytometry and to correlate the nuclear DNA content to the morphological ...

Modern issues of sugar beet (Beta vulgaris L.) hybrid breeding

Вавиловский журнал генетики и селекции, 2021
High efficiency of the cultivation of unfertilized sugar beet ovules and preparation of haploid regenerants (microclones) of pollinators – maintainers of О-type sterility and MS forms of the RMS 120 hybrid components has been shown.
