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 ...

Effects of crossing distance on components of fitness in two rare rock plants

Plant Biology, EarlyView.
Crossing experiments between populations of the rare rock species Saxifraga rosacea ssp. rosacea (8×) and S. rosacea ssp. sponhemica (6×) resulted in heterosis for some traits and outbreeding depression for others. Crossing the two subspecies resulted in sterile hybrids indicating that mixing populations of rare species is not always beneficial ...

Room to regenerate: microhabitats and the recruitment niche as drivers of mountain woodland restoration

Restoration Ecology, EarlyView.
Abstract Introduction Natural regeneration is an efficient, minimal‐intervention approach essential for facilitating resilient, self‐sustaining ecosystems during woodland restoration. However, recruitment can be slow, uncertain, or highly restricted, particularly in mountain woodland systems where tree planting and large herbivore management are ...

Integrating natural baselines into ecosystem restoration: scaling herbivore targets for European landscapes

Restoration Ecology, EarlyView.
Abstract Introduction Herbivore‐mediated ecosystem processes are fundamental to biodiversity, yet have been greatly diminished by megafauna extinctions and replacement of wild herbivores by managed livestock. With increasing restoration ambitions—including the United Nations' (UN) Decade on Ecosystem Restoration and the European Union (EU) Nature ...

Context‐dependent decision‐making in seed sourcing for restoration: reply to Beck et al. (2025)

Restoration Ecology, EarlyView.
Determining the best seed sources for restoration can be a challenge for practitioners, especially under climate change. The number of variables and the spectrum of potential solutions can be daunting. No singular seed sourcing strategy, “local‐is‐best” or otherwise, is appropriate for all species and restoration efforts.
