Sunflower yield stagnation driven by genetic erosion threatens edible oil security, necessitates the integration of adaptive genetic resources.

The experiment was conducted in an augmented block design using six blocks at the Agriculture Research Farm, Hazara University, Mansehra. Data on 9 morpho-yield related traits were analyzed using Analysis of Variance (ANOVA), principal component analysis (PCA), cluster analysis, and correlation…
