The Atlantic salmon aquaculture industry is investigating the feasibility of using sterile triploids to mitigate genetic interactions with wild conspecifics, however, studies investigating diploid and triploid performance often show contrasting results.

Anther culture is an effective breeding method for improving desirable traits, since it allows fast achievement of genetically homozygous lines. The present studies were carried out to evaluate the response of flue-cured tobacco anthers for high frequency pollen embryo induction in different culture media, and the effects of colchicine treatment on tobacco chromosome doubling. The results showed that different media caused significant changes in pollen embryo induction, in which the most obvious change was found in B medium with induction rates of 23.28%, 26.64%, and 28.

To ensure sustainability of aquaculture, plant-based ingredients are being used in feeds to replace marine-derived products. However, plants contain secondary metabolites which can affect food intake and nutrient utilisation of fish. The application of nutritional stimuli during early development can induce long-term changes in animal physiology. Recently, we successfully used this approach to improve the utilisation of plant-based diets in diploid and triploid Atlantic salmon.

Doubled haploid (DH) lines produced via in vivo haploid induction have become indispensable in maize research and practical breeding, so it is important to understand traits characteristics in DH and its corresponding haploids which derived from each DH lines.

Polyploidy, or whole-genome duplication (WGD) promotes genetic diversification in plants. However, whether WGD is accompanied by epigenetic regulation especially DNA methylation remains yet elusive. Methylation of different region in genomic DNA play discrete role in gene regulation and developmental processes in plants.

Cultivated alfalfa was selected from a complex taxonomic group called the Medicago sativa-falcata complex. The complex includes a number of diploid (2n = 2x = 16) and tetraploid (2n = 4x = 32) taxa. Prior information of ploidy is vital for the effective utilisation of genetic resources in alfalfa breeding programs.

Drought and salinity induce biochemical, physiological, morphological, and genetic responses in plants. To understand the damage to different wheat species caused by these stresses, we investigated root-shoot growth, cell division, chromosomal aberrations and nucleolus organizer regions (AgNORs) in root tip cells.
