This study aims at evaluating the yield of cucumber genotypes in two seasons, and identifying cucumber genotypes with high yield and stability. The research has been carried out in the greenhouse of the Department of Horticultural Sciences, University of Guilan, as a factorial experiment in a completely randomized design in autumn and spring seasons with nine cucumber genotypes in three replications. Results show that in terms of number of female flowers in autumn and spring, genotype C1 with an average of 16.7 per plant and genotype C8 with an average of 7.0 per plant have been the best, respectively. Also, in terms of leaf area, C10 genotype with an average of 2866.6 cm2 in autumn and C8 genotype with an average of 9340.990 cm2 in spring outperform the rest and can be used to achieve suitable hybrids for each growing season. Results of principal components analysis and population biplot show that C8 genotype is a suitable genotype for cultivation in two cropping seasons in terms of stability of yield-related traits and vegetative traits. Finally, in terms of number of fruits, genotype C1 with an average of 5.0 per plant in autumn, and C10 genotype with an average of 5.0 per plant in spring have been superior.
