Abstract: The genetic backgrounds of main glutinous rice were analyzed in this study, which were approved in recent years in Heilongjiang Province. The author tries to find out the mainstay parents in pedigree, provides theoretical basis for glutinous rice variety breeding and improvement. The results showed that most of the glutinous rice approved contain the consanguinity of Japanese rice, some mainstay parents can directly breed or derived glutinous rice varieties and lay the foundations for the breeding of glutinous rice. The authors suggested that future breeding program, emphysives on the selection and utilization of mainstay parents.

Key words: glutinous rice, mainstay parents, germplasm resources
