Evaluation of heat stress responses in maize (Zea mays L.) inbred lines derived from different heterotic pools

Key Points

• Inbred lines show varied heat stress responses, impacting overall plant performance.
• Significant differences were observed in stress tolerance among the tested heterotic pools, with some showing notable resilience.
• Observational analysis of plant responses across multiple inbred lines highlights genetic variability in heat tolerance.
• These findings suggest that selecting specific lines may improve resilience in heat-stressed environments, promoting better yields.
