In this paper, we introduce the notion of a variety of graphs closed under isomorphic
images, subgraph identifications and induced subgraphs (induced connected subgraphs)
firstly and next closed under isomorphic images, subgraph identifications, circuits and
cliques. The structure of the corresponding lattices is investigated.
Keywords and phrases: graph, subgraph identification, variety.
