Inbreeding patterns and genetic diversity under selection in Teha sheep

Frontiers in Genetics
BackgroundInbreeding and genetic diversity are critical factors influencing the adaptability, productivity, and sustainability of livestock populations. Teha sheep, a crossbred line between Texel and Kazakh sheep, are an important meat-producing breed in

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.

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.

A Century of Understanding and Harnessing Heterosis

Plant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Genomic Selection for Haploid Induction Rate in Tropical Maize (Zea mays L.) Haploid Inducer Populations: Insights From Heterotic Pools and Recurrent Selection Cycles

Plant Breeding, EarlyView.
ABSTRACT Doubled‐haploid (DH) technology based on in vivo haploid induction has become an effective strategy for accelerating maize breeding. However, improving haploid inducer populations remains challenging because accurate estimation of haploid induction rate (HIR) requires labour‐intensive phenotypic validation, while putative HIR estimates are ...

Underground allies: Mycorrhizal flexibility facilitates orchid occurrence in post‐mining landscapes

Plant Biology, EarlyView.
Epipactis helleborine associates with largely habitat‐specific fungal communities, with limited overlap between mining and woodland sites, yet maintains comparable genetic diversity across habitats. These results highlight the role of mycorrhizal flexibility in enabling habitat shifts and expanding ecological niches in human‐altered landscapes ...

Genetic diversity and population structure analysis of Ethiopian mustard (Brassica carinata A. Braun) accessions using simple sequence repeat markers

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Brassica carinata A. Braun is an oilseed that originated in Ethiopia with a wide range of industrial and food applications. Exploring the genetic structure of the crop is crucial for breeding and conservation measures. Despite the fairly large number of B.
