ESTIMATION OF THE MATING SYSTEM OF Eucalyptus benthamii Maiden at Cambage PROGENY

Revista do Instituto Florestal, 2022
Eucalyptus benthamii is an important species used in monoclonal and hybrid forest plantations around the world. Few natural populations of the species remain, and as such it has been placed on the list of endangered species.

Evaluating Selection Strategies Based on Inbreeding Load via Simulation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.

Studies on association of coefficient of coancestry with progeny performance in sugarcane

Journal of Sugarcane Research, 2021
The utilization of superior parental lines and identification of superior families enhance the genetic gain in sugarcane. To identify the superior parental lines and superior progenies, 1889 progenies derived from twenty crosses involving genetically diverse historical parents were evaluated for juice quality and yield attributing traits.The historical

Identification and validation of quantitative trait loci (QTL) for canine hip dysplasia (CHD) in German Shepherd Dogs. [PDF]

PLoS ONE, 2014
Canine hip dysplasia (CHD) is the most common hereditary skeletal disorder in dogs. To identify common alleles associated with CHD, we genotyped 96 German Shepherd Dogs affected by mild, moderate and severe CHD and 96 breed, sex, age and birth year ...

The richness, frequency and relatedness components of mate diversity and mate portfolios

New Phytologist, EarlyView.
The effects of (a) equal and (b, c) unequal contributions to mate portfolios by 10 mates on (d) Hill‐number mate diversity profiles (see Eqn 1). Summary Sexual reproduction produces genetically diverse families, especially when individuals mate with multiple partners.

Additive Variance and Open‐Pollinated Progenies Under Mixed Mating

Plant Breeding, EarlyView.
ABSTRACT Open‐pollinated progeny tests are still widely interpreted as if all the individuals within a maternal family were true half‐sibs. However, in species with mixed mating systems, this assumption is often biologically unrealistic and may bias the estimation of the additive variance, narrow‐sense heritability and expected selection gains.

Global population structures and demographic history of Suillus luteus, a pine co‐introduced ectomycorrhizal fungus associated with exotic forestry and invasion

New Phytologist, Volume 251, Issue 5, Page 2964-2979, September 2026.
Global phylogenomic tree and phylogenetic network of Suillus luteus and its closely related species. Summary Human colonization since the 19th century has resulted in the global spread of pines beyond their original northern boreal distribution. Although the introduction history of pines is documented through historical records, little is known about ...
