Genomic and phenomic prediction models improve selection accuracy for complex traits in alfalfa

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Predictive breeding has been proposed as an effective approach to accelerate genetic gain for complex traits. Genomic prediction (GP) models have been developed in alfalfa (Medicago sativa L.) for key traits in the last decade. More recently, phenomic prediction (PP) models have been proposed as a low‐cost, high‐throughput alternative to GP in

Development and deployment of a public mid‐density genotyping panel for crimson clover (Trifolium incarnatum L.) based on whole‐genome re‐sequencing of diverse germplasm

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract Crimson clover (Trifolium incarnatum L.) is an obligately outcrossing, cool‐season annual legume valued for forage and cover cropping, yet genomic resources to support systematic improvement are limited. We performed the first whole‐genome re‐sequencing of global crimson clover germplasm to (i) develop a public mid‐density enrichment capture ...

Genomic characterization of a MAGIC population containing introgressions from four tetraploid Gossypium species

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract One strategy for increasing the genetic diversity of upland cotton (Gossypium hirsutum) involves the introgression of beneficial alleles from related and wild tetraploid species. Progress in this area has been limited due to undesirable outcomes associated with whole genome interspecific hybridization. To minimize genetic influences from other

On the extremum principle of natural with inbreeding

, 1997
The extremum principle in the genetical theory of natural selection has been discussed when the population undergoes inbreeding at a constant value of the inbreeding coefficient with constant fitness of the three genotypes possible with two alleles at a ...

Balancing gain and diversity: Optimal contribution selection for sustainable genetic improvement in sugarcane

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract Sugarcane (Saccharum spp. hybrids), the source of ∼80% of the worlds sugar, has experienced a plateau in genetic improvement over recent decades. This stagnation is largely due to the crop's complex polyploid genome and long breeding cycles, which limit the efficiency of traditional selection methods.

Estimation of Inbreeding Depression From Overdominant Loci Using Molecular Markers

Evolutionary Applications
Inbreeding depression is a highly relevant universal phenomenon in population and conservation genetics since it leads to a decline in the fitness of individuals.

Feasibility and pitfalls of combining small subpopulations for genome‐wide association analysis of maize (Zea mays L.) kernel traits

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract Genome‐wide association studies (GWASs) typically require large populations to achieve sufficient statistical power; however, maintaining large populations is labor‐intensive and costly. In this study, we evaluated the feasibility of improving GWAS detection power by strategically integrating small maize (Zea mays L.) subpopulations for kernel‐

Maximizing Genetic Response in Breeding Schemes of Dairy Cattle with Constraints on Variance of Response [PDF]

, 1994
Predicted genetic progress in dairy cattle breeding schemes was maximized with the variances of selection responses constrained, i.e., restricted effective population sizes. This restriction would also lead to schemes with acceptable rates of inbreeding (

Genetic Control of Canalization for Twinning Rates in Polypay and Rambouillet Sheep Using Threshold or Double Hierarchical Generalized Linear Models

Journal of Animal Breeding and Genetics, Volume 143, Issue 6, Page 807-820, November 2026.
ABSTRACT In most sheep production systems, the ideal scenario is for every ewe to lamb and successfully raise twins. However, selection for increased number of lambs born (NLB) is often accompanied by a higher incidence of triplet and higher‐order births, which increases management challenges and producer reluctance to intensify selection for this ...
