Puccinia is the largest genus in the order Pucciniales, with about 3000~4000 described species. Species of Puccinia are especially important and widespread plant pathogens that have a major economic impact on world’s cereal and agricultural crops. There are substantial gaps in the current knowledge of rust diversity status in Uzbekistan. There is still no comprehensive study or even preliminary estimation about the number of Puccinia species and their effect on plants in Central Asia as a whole. Consequently this study aims to first, introduce our ongoing survey on this genus in the study area and then, primarily summarizes the results of previous studies in the region, with special view on its Northeastern Uzbekistan. Here we have reported in total 15 species of Puccinia were found to be parasitic to 25 plant species belonging to 17 genera of Poaceae family in the study region. The following Puccinia species were identified: Puccinia agropyri (Agropyron badamense, Elytrigia repens, E. trichophora, Taeniatherum crinitum), P. brominа (Anisantha tectorum, Bromus tyttholepis, B. danthoniae, B. lanceolatus, B. oxyodon, Buglossa arvensis), P. coronata (Agrostis canina), P. cynodontis (Cynodon dactylon), P. dactylidina (Dactylis glomerata), P. graminis (Hordeum bulbosum, Elytrigia trichophora, Taeniatherum crinitum), P. hordei (Hordeum vulgare), P. isiacae (Phragmites australis), P. moriokaensis (Phragmites australis), P. obtusata (Saccharum spontaneum), P. oryzopsidis (Piptatherum kokanicum, P. vicarium), P. persistens (Agrostis gigantea, Elymus drobovii, Elytrigia repens, E. trichophora, Taeniatherum crinitum), P. poarum (Poa angustifolia, P. annua), P. rufipes (Imperata cylindrica), P. triticina (Triticum spp.).
