In the last 100 years, 94 percent of seed varieties have been lost, and many are still facing extinction, according to the documentary “Seed: The Untold Story,” debuting tonight on “Independent Lens” (PBS, 10 p.m., check local listings). The third in a trilogy of agricultural focused films from Taggart Siegel and Jon Betz, the makers of “Queen of the Sun” and “The Real Dirt on Farmer John,” the film argues that the cause of the loss of diversity has been the monopolization of the field by three chemical companies that include Monsanto and Dupont. The film is produced in part by Marisa Tomei.
A new four-part documentary in the new true crime style, “Killing Richard Glossip” (Investigation Discovery, 9 p.m.) concerns a death row inmate who claims innocence in the 1997 hired-gun murder of an Oklahoma City motel owner. Two episodes show tonight; the concluding two on Tuesday.

Mr. T is out on “Dancing with the Stars” (ABC, 8 p.m.), meaning he won’t get to take part in tonight’s Disney night.

There is some conniving to get the kid the best first grade teacher on “Man with a Plan” (CBS, 8:30 p.m.).
I’m surprised more actors don’t do what William Daniels does when chosen to become guest programmer on Turner Classic Movies: Pick a couple of his own films. Therefore, his selection includes the musical “1776” (8 p.m.), in which he played John Adams, but also “A Thousand Clowns” (11 p.m.) in which he plays the social worker threatening to take away Jason Robards’ son. He’s not in his other choice, the 1936 “Dodsworth” (1:15 a.m.).
