Özet

Background: Soil salinity is a major abiotic stress affecting maize (Zea mays L.) production, leading to reduced germination and yield. Traditional breeding methods are resource-intensive and limited by environmental variability. This study explores machine learning (ML) algorithms to classify salinity stress levels based on germination parameters, aiming to enhance breeding efficiency for salt-tolerant genotypes. Methods: Germination data from 39 maize genotypes were collected under three salinity conditions (0 mM, 100 mM, 200 mM NaCl). Parameters included T10, T50, T90, T10-90, MGT, and Gmax. Data preprocessing involved normalization and feature selection using Correlation-based Feature Selection (CFS). Five ML models BayesNet, Decision Table, Bagging, J48, and Random Forest were evaluated using 10-fold cross-validation, with performance metrics of accuracy, precision, and F-measure. Results: Using all features, Random Forest achieved the highest accuracy (92.02%), followed by BayesNet (89.74%). After CFS (removing genotype and T10-90), BayesNet performed best (89.74%), while Random Forest slightly declined (87.46%). All models exceeded 87% accuracy, demonstrating robust classification of salinity levels. Conclusions: ML models effectively classify salinity stress in maize germination, even without certain parameters, supporting rapid genotype selection. This approach offers a scalable tool for improving agricultural resilience against salinization.
