Cucumis species (Cucurbiatace) are annual monoecious or biannual herbaceous clumbing plants and have rich in minerals and vitamins were collected from Mainpuri district (U.P.). Cucumis sativus have 7 pairs of chromosomes, while Cucumis melo and Cucumis momordica have 12 pairs of chromosomes. Fruits are used as salad, jams and vegetables purposes. Chromosomes pairs are represented in indiogram. The presence of chromosomes may be a reliable cytogenetic information for the screening and frequency. All these species of Cucumis showed the frequencies of half chiasma per chromosome. Anthers were stained by aceto-carmine for mitotic study and meristematic cells were scored. Root tips slides screened to determine the frequency of miotic division of the Cucumis species.
