Abstract
Citrullus species (Cucurbitaceae) were carried out cytogenetically formed 22 chromosomes in Citrullus vulgaris while 24 chromosomes were observed in Citrullus fistolosus. Seeds and fruits are intermediates in shape and size, monoecious or andromonoecious and shows genetic in nature. They are differ in size, only one pair of chromosome is more in Citrullus fistulous. The category of genotypic factors, structure and numeral changes are responsible for variations in chromosome behaviour and structure. Heterotypic one pair of chromosome was clearly established both in mitotic and meiotic study of male diploid plant. Cytogenetically the Cucurbita species can be divided into mesophytic and xerophytic species as Cucurbita pepo, Cucurbita moschatia and Cucurbita maxima. They reported 20 small rod shaped chromosomes in all Cucurbita species. Cucurbita species are numerous and show wide variations in fruit characters. Small size of mitotic chromosome makes them troublesome to count accurately while long chromosomes have pronounced centromere region.
