It is known that many biotic and abiotic characteristics could affect fruit and other reproductive traits in plant species. Knowledge of this effect can play an important role in the selection of conservation and seed collection areas, also cultivation practices of plants. Impact of climatic characteristics on fruit production included minimum, maximum and average temperatures, and annual total precipitation, and together with fertility variation and effective number of parents were investigated in six natural areas of wild rose (Rosa canina L.) during three consecutive years (2020, 2021 and 2022) in this study. Fifty individuals from each area and year were sampled to count the numbers of mature fruits in the species. The studied years among areas, and years within area did not show significant (p > 0.05) differences for the climatic characteristics in contrast to among the areas (p < 0.05) for the minimum temperature and monthly total precipitation of pooled years. Averages of fruit productions varied for the populations and years, and among individuals within an area. Years showed significant (p < 0.05) differences for fruit productions of pooled areas in contrast to areas of pooled years (p > 0.05) based on results analysis of variance. The studied climatic characteristics had no significant (p > 0.05) impact on fruit productions in pooled years and areas. Estimated fertility variations were at acceptable level for the areas and years. It ranged from 1.10 (91% of fertility individuals) to 2.22 (45%) in the areas.
