Twelve varieties of Cucumber (Cucumis sativus L) were evaluated for yield and yield components in a randomized complete block design replicated three times at the Michael Okpara University of Agriculture, Umudike in 2020 and 2021. Data were collected on the length of the main vine, the number of leaves plant-1, number of vines plant-1, number of fruits plant-1, fruit diameter, the weight of fruit plant-1, length of fruit and fruit yield-1. Analysis of variance showed that the varieties differed significantly (P<0.05) in all the attributes studied. Thai 986, Thai 999 and Cu 4315, recorded superior vegetative and reproductive characters performance, and also recorded higher fruit yield in both 2020 and 2021. Except for the length of fruit, all the vegetative and reproductive characters had positive and significant associations with fruit yield ha-1.
