NEW YORK — “Roseanne” will return to ABC two decades after it wrapped its hit run and with star Roseanne Barr and the rest of the cast intact, the network said in announcing its 2017-18 season plans.

“The Conners’ joys and struggles are as relevant — and hilarious — today as they were then, and there’s really no one better to comment on our modern America than Roseanne,” ABC Entertainment President Channing Dungey said in a statement. The eight-episode reboot will air in 2018.

The network also announced plans for a new “Grey’s Anatomy” spinoff. Set in a Seattle firehouse, the untitled drama, to be executive produced by Shonda Rhimes, has no air date.

ABC’s lineup next season include one familiar reality series, “American Idol,” and Katy Perry will join as one of the show’s judges.

A new comedy, “The Mayor,” stars Brandon Micheal Hall as a young rapper who unexpectedly wins a mayoral election in his hometown.

Another new comedy, “Alex Inc.,” is set for the 2017-18 season but with a still-unannounced debut date. Zach Braff stars as a radio journalist and family man who decides to turn entrepreneur.

Three new dramas are set for a fall debut: “The Good Doctor,” starring Freddie Highmore as a young physician with autism and savant syndrome; “The Gospel of Kevin,” about a troubled man who’s instructed by a celestial being to save the world, and “Marvel’s Inhumans.” The comic-book based series will explore the story of Black Bolt, king of the inhumans, and his royal family splintered by a military coup.
