The anomalies of generative and vegetative organs of species of the genus Allium L., which occur under the influence of environmental factors, both in prevalent natural areas, and during introduction into agriculture in the territory of the Republic of Azerbaijan, have been investigated. In some species of onion A.waldsteinii Don. in the ecological conditions of their natural germination, along with seeds, the appearance of air bulbs (profilication - replacement of one organ by another) was observed in floral umbrellas. Anomalies such as fasciation (fusion of organs among themselves), deformation (change of form) and prolification occurred in the structural elements of the species (A. waldsteinii Don., A.erubescens C.Koch., A.fuscoviolaceum Fom., A.viride Grossh) introduced into the agriculture. Prolification occurred in the Khachmaz variety of onion (A.cepa L.) and germination of air bulbs in umbrellas was observed in the Jalilabad variety of garlic (A.sativum L.)
