Conversation with my boss Winter 1978- University of Tennessee Gene: My Dad wants to know what cotton variety he should plant next year. Phillip Hoskinson: Hmm. Tell your father that will depend on the weather. If I knew what the weather is going to be, then I could tell him the best cotton variety to plant.
