Effect of polyploidization on morphology in two apple (Malus × domestica) genotypes

Horticultural Science, 2017
Because polyploidy often results in enhancement of desirable properties, artificial genome doubling is commonly used in agri- and horticultural crop breeding programs. In this study genome doubling was induced in two apple genotypes.

Chromosome doubling can increase heat tolerance in Lonicera japonica as indicated by chlorophyll fluorescence imaging

Biologia Plantarum, 2011
Imaging fluorometry was applied to investigate the tolerance of Japanese honeysuckle (Lonicera japonica Thunb.) of different ploidy levels to heat stress. Seedlings of L. japonica, the diploid cv. Damaohua and the tetraploid cv.

Polyploid plants have faster rates of multivariate niche differentiation than their diploid relatives.

Ecology Letters, 2019
Polyploid speciation entails substantial and rapid postzygotic reproductive isolation of nascent species that are initially sympatric with one or both parents.

Establishment and Optimization of an Experiment System for Flow Cytometry in Oil-Seed Camellia

Horticulturae
Ploidy identification is a basic method for determining germplasm resources and for breeding new varieties of oil-seed camellia. In this study, flow cytometry and K-mer analysis were used to identify the ploidy of oil-seed camellia germplasms.

Genetic diversity and population structure of bermudagrass (Cynodon spp.) revealed by genotyping-by-sequencing

Frontiers in Plant Science, 2023
Bermudagrass (Cynodon spp.) breeding and cultivar development is hampered by limited information regarding its genetic and phenotypic diversity. To explore diversity in bermudagrass, a total of 206 Cynodon accessions consisting of 193 common bermudagrass
