In Vivo Haploid Induction in Maize: Identification of Haploid Seeds by Their Oil Content
Crop Science, 2014ABSTRACTIn 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

Identification and propagation of haploid human pluripotent stem cells
Nature Protocols, 2016Haploid human pluripotent stem cells (PSCs) integrate haploidy and pluripotency, providing a novel system for functional genomics and developmental research in humans. We have recently derived haploid human embryonic stem cells (ESCs) by parthenogenesis and demonstrated their wide differentiation potential and applicability for genetic screening ...

Improving the identification of haploid maize seeds using convolutional neural networks
Crop Science, 2021AbstractA critical step toward the success of the doubled haploid (DH) technique is the haploid identification within induction crosses. The R1‐nj marker is the principal mechanism employed in this task enabling the selection of haploids at the seed stage.

Anemone coronaria L. (2n=2x=16) is a perennial, allogamous, and highly heterozygous plant belonging to the Ranunculaceae family, marketed both as cut flower and garden plant. The production of F1 hybrids obtained by crossing highly homozygous inbred lines is hampered by the marked inbreeding depression characterizing the species.

DNA fingerprinting in sugar beet (Beta vulgaris) — identification of double-haploid breeding lines
Theoretical and Applied Genetics, 1993The distribution and abundance of simple repetitive sequences complementary to the synthetic oligonucleotides (GACA)4, (GATA)4, (GTG)5 and (CA)8 in the genomes of several cultivars of Beta vulgaris and in the wild beet B. vulgaris ssp. maritima were investigated.

Generation, identification, formation mechanism and application of plant haploids.
Yi chuan = Hereditas, 2017Haploids are individuals with gametophytic chromosome numbers. Homozygous doubled haploids can be quickly gained by genome doubling. Haploids and doubled haploids play an important role on crop breeding, mutant screening, gene functional analysis, cytological studies, construction of genetic population and so on, and have been a research hotspot of ...

Identification of Cotton Haploids by Stomatal Chloroplast‐count Technique1
Crop Science, 1975Chloroplast counts were made from the stomatal guard cells in haploid (n = 2x = 26) and in natural tetraploid (2n = 4x = 52) plants of Gossypium hirsutum L. and G. barbadense L. The mean chloroplast number was 10.46 ± 2.18 for haploids and 21.00 ± 3.31 for tetraploids.

The frequency of haploid production following the interspecific pollination of eight tetraploid potato cultivars (Solanum tuberosum subsp. tuberosum) with Solanum phureja clone 1.22 was investigated. A total of 185 haploids were produced with an overall haploid frequency of 3.9 haploids/100 fruits.

Identification of novel regulators of sprouting angiogenesis using haploid ES cells
2017Blood vessel expansion, remodelling and maturation is a major physiological event that fulfils the embryonic developmental stages and takes part in adult pathophysiology such as ocular diseases or cancer development. The cascade of events that leads to the formation of new blood vessels from already existing ones is termed angiogenesis.

Induction, separation and identification of haploid strains from industrial brewer's yeast.
Wei sheng wu xue bao = Acta microbiologica Sinica, 2015Lager brewing yeasts (Saccharomyces pastorianus), the natural hybrids of S. cerevisiae and S. eubayanus, are usually heterothallic polyploidy or aneuploidy. Their intricate ploidy is a great challenge to genetic studies and strain improvement. Haploid breeding is an effective method to overcome these difficulties.
