Change in genetic size of small-closed populations: lessons from a domestic mammal population

Genetics and Molecular Biology, 2010
The aim of this study was to monitor changes in genetic size of a small-closed population of Iranian Zandi sheep, by using pedigree information from animals born between 1991 and 2005.

The cotton historical lines project—Part I: History and field evaluation

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Common garden experiments have provided great insights into crop adaptation across many systems. Cotton (Gossypium spp.) cultivars have changed in the 20th and 21st centuries, but breeders have not quantified the degree of these changes. We synthesized a panel of 164 non‐genetically modified genotypes, from the private and public sectors ...

Genomic Evidence of Low Contemporary Effective Population Size and Southern Genetic Reservoirs in an Island Endemic Epiphytic Orchid of Taiwan

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Genome‐wide data from ddRADseq revealed a latitudinal gradient in genetic diversity in a Taiwanese endemic orchid. This study shows that genomic data not only can help us understand the evolutionary origins of genetic diversity in a species but also uncover its genetic reservoir for future conservation planning.

Testing the usefulness of the molecular coancestry information to assess genetic relationships in livestock using a set of Spanish sheep breeds [PDF]

, 2010
Recent studies have proposed the use of molecular coancestry coefficients as a measure of genetic variability and as a useful tool for conservation purposes.

Effect of linkage on the control of inbreeding in selection programmes

Genetics Selection Evolution, 2000
Selection and mating methods for controlling inbreeding in selection programmes are based on relationships obtained from pedigrees. The efficiency of these methods has always been tested by studies using genetic models of independent loci. However, under

Analysis of Genetic Variation of Rice Straw Characteristics and Its Influence on Biomass

Plant Direct, Volume 10, Issue 1, January 2026.
ABSTRACT Rice straw is a key source of lignocellulosic biomass. GWAS can be used to identify genetic loci controlling stem morphological traits that influence biomass. This study aimed to investigate the genotypic diversity of rice straw internodes through GWAS, using 34,232 single‐nucleotide polymorphic sites with a minor allelic frequency (MAF ...

Inbreeding and founder cultivars contributions in low chill requirement peaches and nectarines

Crop Breeding and Applied Biotechnology, 2023
The pedigree analysis from genealogical data can estimate the inbreeding from identity-by-descent, being a powerful tool for germplasm characterization. The aim of this study was to evaluate the genetic diversity of peach and nectarine cultivars from the

Genomic Connectivity and Adaptation Signals of the Freshwater Sponge Ephydatia muelleri Across Its Distribution

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Genetic connectivity and local adaptation were examined across the distribution of the freshwater sponge Ephydatia muelleri. Because it occupies an exceptional breadth of freshwater environments across a broad geographic range, this species offers key insights into biogeographic processes shaping genetic structure and adaptation in inland ...

Mating system in a Hevea brasiliensis population by isozyme loci

Crop Breeding and Applied Biotechnology, 2005
The multilocus mixed mating model and correlated mating model were used to analyze the mating system of a natural Hevea brasiliensis (Willd. Ex Adr. of Juss.) population from the State of Acre.
