Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Ancestral Inbreeding Only Minimally Affects Inbreeding Depression in Mammalian Populations [PDF]

Journal of Heredity, 1997
Inbreeding depression can be reduced, or purged, by selection against deleterious alleles. This prediction is the basis of the recommendation that captive wildlife populations suffering from inbreeding depression be intentionally bred from healthy inbred animals. Yet data on the effectiveness of purging inbreeding depression are few.

Genotypic Variation and Association Mapping for Plant Stature and Anthesis‐Silking Interval in Set of Temperate‐Adapted Maize Lines Developed by DH and SSD Methods

Plant Breeding, EarlyView.
ABSTRACT BS39 is a broad‐based population of tropical maize adapted to temperate environments that can provide useful and unique alleles to US Corn Belt breeding programmes. Doubled‐haploid (DH) has been used as an efficient alternative method to speed up the development of maize lines. Our objectives were to compare genetic parameters for plant height

Potato dihaploids uncover diverse alleles to facilitate diploid potato breeding

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Commercial potato (Solanum tuberosum) in North America is a clonal autotetraploid crop, which complicates breeding. Efforts are underway to convert potato to a diploid inbred‐hybrid crop, allowing breeders to more quickly meet market and environmental demands.

EFFECT OF INBREEDING ON LOIN AND FAT DEPTH IN HUNGARIAN LANDRACE PIGS [PDF]

Poljoprivreda, 2007
Pedigree and field test data - collected between 1997-2005 - were analyzed in a group of 68062 Hungarian Landrace pigs. The analysed traits were loin depth (LD), fat depth1 (FD1) and fat depth2 (FD2).

Seascape Genomics Uncovers Genomic Patterns Shaped by Temperature and Salinity Outlier Loci in Dolphinfish (Coryphaena hippurus Linnaeus, 1758) Across the Atlantic Ocean and Mediterranean Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT In this study, we explored the population genetic structure and its relation to environmental adaptations of the dolphinfish (Coryphaena hippurus) in the western Atlantic Ocean and Mediterranean Sea. Although previously two populations within the Mediterranean Sea were identified, recent evidence suggests more complex structuring.

The genetic basis of inbreeding depression

Genetical Research, 1999
Data on the effects of inbreeding on fitness components are reviewed in the light of population genetic models of the possible genetic causes of inbreeding depression. Deleterious mutations probably play a major role in causing inbreeding depression.

Population Structure and Genetic Diversity Analyses Reveal Isolation That May Imperil the Northernmost Colony of the Endangered Australian Sea Lion

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Rapid warming of marine environments is threatening ecosystems, especially species at the edge of their range. This study analysed the genetic structure and diversity of Australian sea lion populations and found the northernmost population to be highly isolated with extremely low genetic variation.

A major QTL affects temperature sensitive adult lethality and inbreeding depression in life span in Drosophila melanogaster

BMC Evolutionary Biology, 2008
Background The study of inbreeding depression has major relevance for many disciplines, including conservation genetics and evolutionary biology. Still, the molecular genetic basis of this phenomenon remains poorly characterised, as knowledge on the ...
