Narcissus, a prominent perennial ornamental bulbous plant, serves both aesthetic and practical purposes as a cut flower. This study aimed to assess the impact of climatic conditions on flower yield in native narcissus populations in Ahvaz. The experiment was designed as a randomized complete block with three replications, conducted between 2020 and 2022 at Chamran University's research farm in Ahvaz, Iran. Native narcissus genotypes collected from diverse regions of the country were cultivated and subjected to a comprehensive evaluation of morphological indices. The analysis of variance (ANOVA) underscored significant differences in all morphological parameters at a 1% probability level, showcasing the diversity among the genotypes. Phenotypic correlations unveiled robust positive associations between most traits, underscoring their interdependence. Principal component and cluster analyses offered a holistic perspective on the dataset. The first three principal components encapsulated 87.15% of the total variability, with the primary component (PC1) spotlighting the most influential traits driving genotype divergence. Cluster analysis delineated the eleven genotypes into three distinct clusters, indicative of notable variations in morphological attributes among the genotypes. This study furnishes valuable insights into the intricate relationships between diverse traits and flower numbers in daffodil genotypes, providing a foundation for informed breeding decisions. Comprehending the complex interplay of these traits through correlation and multivariate analyses is pivotal for advancing daffodil breeding programs and enhancing multiplication capacity. These findings not only inform daffodil breeding initiatives in Iran but also lay a groundwork for similar studies in other plant species. تفاصيل المقالة
