Solution(By Examveda Team)

Ug 99 race specific to Puccinia graminis tritici.
Ug 99 is a lineage of wheat stem rust (Puccinia graminis f. sp. tritici), which is present in wheat fields.
It is predicted to spread rapidly through these regions and possibly further afield, potentially causing a wheat production disaster that would affect food security worldwide.
Ug 99 and its variants differ from other strains of the Black Stem Rust pathogen due to their ability to overcome resistance genes in wheat that has been durable against the BSR pathogen for decades.
