Meiotic Chromosome Stability and Suppression of Crossover Between Non-homologous Chromosomes in xBrassicoraphanus, an Intergeneric Allotetraploid Derived From a Cross Between Brassica rapa and Raphanus sativus

Frontiers in Plant Science, 2020
Hybridization and polyploidization are major driving forces in plant evolution. Allopolyploids can be occasionally formed from a cross between distantly related species but often suffer from chromosome instability and infertility. xBrassicoraphanus is an

Testing of triploid poplar hybrids in Voronezh region [PDF]

Сибирский лесной журнал, 2016
The paper presents new data on 28-30-year-olds testing of triploid poplar hybrids (2n = 3x = 57), obtained using in hybridization artificially obtained unreduced diploid (2n) pollen (induced by high temperature or colchicines treatment) in Voronezh ...

Analysis of the progeny of unreduced male gametes producers and non-producers of Turnerasidoides (Passifloraceae) [PDF]

, 2014
La unión de gametos 2n ha tenido un importante papel en el origen de los poliploides de Turnera sidoides. Sin embargo, como en este complejo la tasa de formación de neopoliploides es baja, el establecimiento de los mismos constituiría una etapa crítica ...

Genetic variability of anther donor versus spontaneous doubled haploid descendents and colchicine induced doubled haploid sweet pepper (Capsicum annuum L.) lines [PDF]

, 2001
Haploid (n) and doubled haploid (DH) plants were developed in anther culture of sweet pepper (Capsicum annuum L.). Regenerants were analyzed by flow cytometry for haploid (n = 12) and spontaneous doubled haploid (2n = 24) genomes.

An investigation into the efficacy of Biokos® in controlling ciliates in laboratory cultures of Saccharina latissima gametophytes

Journal of Phycology, EarlyView.
Abstract A major challenge faced by kelp aquaculture operations is the control of contaminants, including by marine ciliates. Biokos® is a commercially available treatment for ciliate parasites in fish, in which the active ingredient is a viscosin‐like lipopeptide surfactant.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Meiotic observation on ‘Bartzella’, an intersectional hybrid of Paeonia

Xibei zhiwu xuebao
[Objective] Most intersectional hybrids in Paeonia are triploids and generally sterile, producing a small number of hybrid offspring. Observing the meiotic chromosome behaviors of ‘Bartzella’, an intersectional hybrid with high ornamental value and ...
