In order to evaluate of agronomical traits and fruit yield in 23 breeding hybrid cultivars of greenhouse cucumber, and determine the relationship between these traits, a randomized complete block design with three replications was performed in the research greenhouse of Islamic Azad University, Isfahan (Khorasgan) Branch in 2014-15. Data was collected for these traits: total fruit yield, total fruit number, number and fruit yield on three periods, plant height, length and width of leaf, length and diameter of fruit, days to flowering and fruiting and the first flower node. Coefficient of correlations showed that total number of fruit and fruit diameter had significant and positive correlation with fruit yield. Path analysis revealed that fruit number had the highest direct and positive effect on fruit yield. Therefore this trait could be used as selection criterion for selecting genotypes with high fruit yield. Step wise regression showed that total fruit yield and fruit yield on mid fruit production period explained 96.30 percentage of fruit yield variation. On the other hand, total fruit yield and fruit number on final fruit production period explained the highest amount of total fruit number variation.
