Synopsis

Bonanza is set around the Ponderosa Ranch near Virginia City, Nevada and chronicles the weekly adventures of the Cartwright family, consisting of Ben Cartwright (Lorne Greene) and his three sons (each by a different wife), Adam (Pernell Roberts), Eric "Hoss" (Dan Blocker), and Joseph (Michael Landon). Veteran actor Victor Sen Yung played the ranch cook, Hop Sing. In 1964, Pernell Roberts began expressing a desire to leave the series, and so prospective replacements were introduced via Barry Coe as Little Joe's wayward maternal half-brother Clay, and Guy Williams as Ben's nephew Will Cartwright. However, Roberts was persuaded to complete his contract, and remained through season six. The characters of Clay and Will were discontinued. In the ninth season, David Canary was added to the cast as ranch hand/foreman Candy Canady. After four years with the series, Canary left due to a contract dispute. In the twelfth season, Mitch Vogel joined the cast as Jamie Hunter, a teenage orphan who is adopted by Ben Cartwright.
