Summary

This 2025 narrative review integrates breeding science with field agronomic evidence to evaluate when cultivar mixtures outperform monocultures in small grain cereals, and when pure stands remain preferable. The authors examine mechanisms underpinning disease resilience and yield stability—traits increasingly relevant to climate adaptation—whilst critically examining practical trade-offs in yield potential, market standards and farmer feasibility. The work provides nuanced, evidence-grounded guidance on variety mixture deployment in cereal production systems.

UK applicability

The review's conclusions on disease resilience from variety mixtures are directly relevant to United Kingdom cereal production, where disease pressure (septoria, mildew, rust) is a major driver of fungicide use. UK farmers and breeders may find the guidance on adoption barriers and market compatibility particularly applicable to transitioning towards more diverse cereal cropping systems.

Key measures

Disease pressure, yield stability, yield potential, genetic diversity, market compliance, farmer feasibility, climate adaptation capacity

Outcomes reported

This narrative review synthesises evidence on the agronomic, breeding and sustainability trade-offs between variety mixtures and pure stands in small grain cereals. The authors assess mechanisms of disease resilience and yield stability, and evaluate practical constraints including yield potential, market standards and farmer adoption feasibility.
