Use of 2n Gametes in Plant Breeding
, 2012 Genome doubling (polyploidization) has played a major role in the evolution and diversification of the plant kingdom and is regarded as an important mechanism of speciation and adaptation in plants (Otto & Whitton, 2000).

Origin of 2N gametes in C. reticulata cv fortune mandarin [PDF]
, 2009 Citrus are most important fruit crop worldwide. Seed1essness is a key characteristic for the fresh fruit market and the development of triploid hybrids is one strategy developed by several groups over the world.

A Trojan horse inside the gates: Alien-native mating interactions in mixed populations of Solidago taxa. [PDF]
Plant Biol (Stuttg)DAPI flow cytometry identified post‐invasion processes—hybridisation, introgression, and polyploidization—in mixed populations of Solidago canadensis, S. virgaurea and S. ×niederederi. Abstract The establishment and possible impacts of alien–native hybrids depend on their formation frequency and ability to spread using generative and vegetative ...

G3: Genes, Genomes, Genetics, 2021 Unreduced gametes (2n gametes), possessing double the haploid genome, whatever ploidy that happens to be, are a common source of ploidy variation in plant populations.

Genomic introgressions from wild relatives in the wheat genome alter meiotic dynamics in inter-varietal hybrids. [PDF]
Plant JSUMMARY The use of wild relatives to introduce original diversity in the genome of bread wheat (Triticum aestivum L.) is an interesting approach to face the challenges of sustainable agriculture and the impact of climate change on wheat production. However, the influence of these wild‐species introgressions on meiosis in inter‐varietal wheat hybrids ...

Unreduced Male Gamete Formation in Cymbidium and Its Use for Developing Sexual Polyploid Cultivars
Frontiers in Plant Science, 2020 Polyploidy plays an important role in crop improvement. Polyploid plants, particularly those produced through unreduced gametes (2n gametes), show increased organ size, improved buffering capacity for deleterious mutations, and enhanced heterozygosity ...

Relevance of unilateral and bilateral sexual polyploidization in relation to intergenomic recombination and introgression in Lilium species hybrids [PDF]
, 2002 Sexual polyploids were induced in diploid (2n = 2x = 24) interspecific F1 hybrids of Longiflorum × Asiatic (LA) and Oriental × Asiatic (OA) Lilium hybrids by backcrossing to Asiatic (AA) parents as well as by sib-mating of the F1 LA hybrids.

Asynapsis and unreduced gamete formation in a Trifolium interspecific hybrid
BMC Plant Biology, 2022 Background Unreduced gametes, a driving force in the widespread polyploidization and speciation of flowering plants, occur relatively frequently in interspecific or intergeneric hybrids. Studies of the mechanisms leading to 2n gamete formation, mainly in

Folia Horticulturae, 2021 Pollen characteristics are very important for Iris interspecific hybridisation. In this study, the pollen viability and male meiosis were studied in yellow-flowered Iris dichotoma (Y2), I. domestica (S3) and their hybrids F1, F2 and BC1 (BC1-Y and BC1-S).

2n Gamete formation in the genus Brachiaria (Poaceae: Paniceae) [PDF]
Euphytica, 2006 Microsporogenesis of several Brachiaria species of the Brazilian collection at Embrapa Beef Cattle has been analyzed in detail. This paper reports abnormal cytokinesis in three accessions of three different species (Brachiaria humidicola, 2n = 4x = 36, Brachiaria decumbens, 2n = 4x = 36, and Brachiaria dura, 2n = 6x = 54).
