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

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

Opportunities and Challenges in Doubled Haploids and Haploid Inducer-Mediated Genome-Editing Systems in Cucurbits

Agronomy, 2020
Doubled haploids have played a major role in cucurbit breeding for the past four decades. In situ parthenogenesis via irradiated pollen is the preferred technique to obtain haploid plantlets whose chromosomes are then doubled in Cucurbitaceae, such as ...

Optimization of technology steps for obtaining white cabbage DH-plants [PDF]

Вавиловский журнал генетики и селекции
White cabbage is one of the economically important crops among the representatives of the genus Brassica L. To create highly productive F1 hybrids with improved characteristics, the breeders need genetically diverse breeding material, which takes a long ...

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.

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.

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.

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

Popcorn (Zea mays L. var. Everta) haploids identified by Navajo phenotype and ploidy level

Frontiers in Plant Science, 2023
For popcorn, obtaining and identifying haploids are still challenging steps. We aimed to induce and screen haploids in popcorn using the Navajo phenotype, seedling vigor, and ploidy level.
