Quadrotriticale

Quadrotriticale was a high-yield, perennial, four-lobed grain, genetically engineered hybrid of wheat and rye. It was the only Earth grain able to grow on Sherman's Planet, and in 2267, several tons of quadrotriticale were shipped to space station Deep Space K-7, bound for Sherman's Planet. This grain was poisoned by Klingon agents trying to undermine Federation colonization; this espionage was discovered when tribbles consumed the majority of the grain. (TOS episode: "The Trouble With Tribbles")

In 2373, Quark invested heavily in quadrotriticale futures, and suffered heavy financial losses. (DS9 episode: "Business as Usual")
