Yam (Dioscorea spp.) is propagated vegetatively from its areal and underground tubers. Its development effort, like that of many other vegetative propagated crops grown in the country, is carried out through the collection, characterisation, and evaluation of germplasms discovered in farmers’ fields. The purpose of this study was to investigate yam (Dioscorea spp.) flowering and botanical seed germination in order to improve genetics and conserve the species. The research was carried out in Ethiopia’s Gedio Zone, Wonago district. In this study, 60 yam clones from six different species were obtained from various key growing regions around the country. Botanical seeds from open pollinated fields exhibited a wide range of diversity. Male, female, and none blooming plants were found in 21, 12, and 27 genotypes, respectively, among 60 yam germplasms. This revealed that female yam plants are less common than male yam plants in the yam population. 85 percent of botanical seeds germinated in this study, resulting in healthy and vigorous yam seedlings. As a result, utilising botanical seeds obtained through open pollination, it is possible to increase yam genetic variety. It will, in reality, be an alternate method for conserving yam and other root and tuber crops germplasms with botanical seeds in order to reduce genetic degradation at field gene banks due to biotic and abiotic causes.
