Abstract: Bread wheat (Triticum aestivum L.) is the most widespread self-pollinating crop worldwide, belonging to the Gramineae (Poaceae) botanical family. Correlation coefficients highlight the degree of association between different traits, thus helping the selection process for obtaining new high-yield wheat varieties.

This study aimed to characterize 20 wheat genotypes from the germplasm collection of the Vegetal Genetic Resources Bank “Mihai Cristea” Suceava (SVGB). Wheat cultivars were analyzed for different morphological and yield traits between 2021 and 2023 at the IULS Ezareni Research Farm. Genotypic and phenotypic variability for different traits was highlighted, and the relationships between different types of traits were estimated using Pearson correlations. The traits analyzed include plant height, spike density, glume color, awns, presence of hairs on glumes, and grain yield. The results show that the wheat germplasm from SVGB has high variability and high agronomic value, and the genotypes studied can be introduced as initial material in wheat breeding programs.
