Cenh3: An Emerging Player in Haploid Induction Technology. [PDF]

Frontiers in Plant Science, 2016
True-breeding lines are required for the development and production of crop varieties. In a classical breeding approach these lines are obtained through inbreeding, and often 7-9 generations of inbreeding is performed to achieve the desired level of ...

Dissecting the genetic variation of haploid frailty in maize for enhanced doubled haploid breeding. [PDF]

Front Plant Sci
Haploid frailty (HF), the reduced vigour of haploids compared to their diploid counterparts, limits the efficiency of doubled haploid (DH) breeding in maize.

Embryogenesis induction of carrot (Daucus carota L.) in isolated microspore culture

Foods and Raw Materials, 2023
Haploid technologies are used to create homozygous lines for accelerated breeding. We aimed to optimize the technology for using the isolated microspore culture in vitro to obtain doubled haploids of the carrot (Daucus carota L.).

Discrimination of haploids and doubled haploids/diploids in indica rice: correlation of morphological indicators with molecular markers

Biologia Plantarum, 2023
To obtain immediate homozygosity by androgenesis, the doubled haploid method is often used. As a result, a mapping population was created utilizing rice (Oryza sativa L.) cvs.

Variability of morphological features and nuclear DNA content in haploids and doubled haploids of androgenic callus lines of rice (Oryza sativa L.)

Труды по прикладной ботанике, генетике и селекции, 2022
The work is relevant for understanding evolutionary processes in plant species. Twelve callus lines with multiple regeneration of haploids and doubled haploids were obtained in F1 hybrids of Oryza sativa L. through in vitro androgenesis.

Mendel’s Laws and their impact on plant breeding

Journal für Kulturpflanzen, 2022
Cereals like wheat, rice, maize, barley and millets, feed the world. Therefore, global breeding activities, which had been very successful during the last decades, aim at an increase of cereal yields.

A novel visual marker to distinguish haploids from doubled haploids in rice (Oryza sativa, L) at early growth stages

Plant Methods, 2023
Doubled haploid technology, which enables the generation of homozygous lines in a single step, is one of the modern tools being employed for accelerating breeding processes in different crops.

Haploid induction in tropical supersweet corn and ploidy determination at the seedling stage [PDF]

Pesquisa Agropecuária Brasileira, 2020
: The objective of this work was to determine the possibility of haploid induction in tropical supersweet corn (Zea mays L. var. saccharata) using a maternal inducer, as well as to identify alternative methods for haploid selection. A single-cross hybrid

Evolution of Reproductive Division of Labor – Lessons Learned From the Social Amoeba Dictyostelium discoideum During Its Multicellular Development

Frontiers in Cell and Developmental Biology, 2021
The origin of multicellular life from unicellular beings is an epochal step in the evolution of eukaryotes. There are several factors influencing cell fate choices during differentiation and morphogenesis of an organism. Genetic make-up of two cells that

De novo construction of polyploid linkage maps using discrete graphical models [PDF]

, 2018
Linkage maps are used to identify the location of genes responsible for traits and diseases. New sequencing techniques have created opportunities to substantially increase the density of genetic markers.
