Weighted Single‐Step GWAS Reveals Genetic Mechanisms Underlying Pregnancy Loss in Early Nellore Heifers

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Pregnancy loss (PL) affects reproductive efficiency in beef cattle, yet its genetic architecture remains poorly understood in Bos indicus populations. Here, PL was defined as failure from pregnancy diagnosis to calving, capturing a window approximately 60 days after the breeding season.

Groundnut Improvement for Aflatoxin Resistance: Progress and Opportunities

Food and Energy Security, Volume 15, Issue 5, September/October 2026.
ABSTRACT Groundnut, or peanut, is an industrial oilseed crop that serves the food and feed industries and provides income along the value chain. Pre‐ and post‐harvest aflatoxin contamination, caused by Aspergillus spp., hinders the food and feed value and market opportunities of groundnut products. Developing and deploying aflatoxin‐resistant varieties

Genomic prediction in quinoa across contrasting environments using statistical and machine learning models

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Quinoa (Chenopodium quinoa Willd.) is gaining global importance for its nutritional value and adaptability; however, breeding progress remains limited. Genomic selection (GS), combined with rapid generation cycles, offers a strategy to accelerate genetic improvement.

Early Selection Enabled by the Implementation of Genomic Selection in Coffea arabica Breeding

Frontiers in Plant Science, 2019
Genomic Selection (GS) has allowed the maximization of genetic gains per unit time in several annual and perennial plant species. However, no GS studies have addressed Coffea arabica, the most economically important species of the genus Coffea. Therefore,

Harnessing exotic germplasm for red clover improvement: Tracking genomic introgression and deploying genomic selection

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Red clover (Trifolium pratense L.) is a globally important temperate forage legume. Its symbiosis with soil‐borne rhizobia enables nitrogen fixation, and its ability to produce quality forage under diverse soil conditions enhances pasture productivity, particularly during water deficits.

Integrative genomics and zero‐shot deep learning–based phenotyping reveal the genetic architecture of seed traits in mungbean (Vigna radiata L.)

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Improving seed size and weight is a major breeding goal in mungbean (Vigna radiata (L.) R. Wilczek). Improved genomic resources and precision phenotyping may enable more efficient selection for seed trait improvement. In this study, we integrated a deep learning–based segment anything model phenotyping pipeline with genome‐wide association ...

Weighting strategies for single-step genomic BLUP: an iterative approach for accurate calculation of GEBV and GWAS

Frontiers in Genetics, 2016
Genomic Best Linear Unbiased Predictor (GBLUP) assumes equal variance for all single nucleotide polymorphisms (SNP). When traits are influenced by major SNP, Bayesian methods have the advantage of SNP selection.

Comparison of analyses of the XV^th QTLMAS common dataset III: Genomic Estimations of Breeding Values

BMC Proceedings, 2012
Background The QTLMAS XVth dataset consisted of pedigree, marker genotypes and quantitative trait performances of animals with a sib family structure. Pedigree and genotypes concerned 3,000 progenies among those 2,000 were phenotyped.

Effect of enlarging the number of reference population cows and imputed markers on reliability of genomic prediction in Jersey breed

پژوهشهای علوم دامی ایران, 2015
The objective of this study was to evaluate the potential gain in accuracy of predictions by imputing genotypes from a low-density marker panel (6640 marker with 10 replicates) to a medium-density marker panel in a simulated population of Jersey cattle ...

Multigenerational prediction of genetic values using genome-enabled prediction.

PLoS ONE, 2019
The identification of elite individuals is a critical component of most breeding programs. However, the achievement of this goal is limited by the high cost of phenotyping and experimental research.
