Greyhound Corp. said it may sell its bus business.

It also has received strong interest from potential buyers in response to feelers put out by a New York investment banker, the parent of the nation’s largest bus operation said. Phoenix-based Greyhound has hired Morgan Stanley & Co. to seek investors who might want to buy the Greyhound Lines Inc. subsidiary, said Greyhound Vice President L. Gene Lemon. He said Morgan Stanley’s initial mailing of offering documents had drawn strong interest. But Lemon would not identify prospective buyers and said the company had not definitely decided to sell.
