      Short staple variety trials were grown in two locations in Graham county in 1990, Thatcher in the central part of the valley and Eden on the west end Acala Prema from the San Joaquin Valley in California had the top seed cotton yield in both locations with yield of 3789 and 3162 pounds per acre, at the two locations, respectively. The average lint yield in the Thatcher site was down more than 200 pounds per acre from 1989, whereas the average at the Eden site was about the same as in 1989. 1990 is characterized by its record setting heat spell in the end of June, even though fewer heat units were received in 1990 than in 1989. HS 46, a variety first seen in Graham county in 1989, performed well in both sites and in fact, topped both trials with lint yield Data on yields, percent first pick, plant height and plant populations are presented for each variety in each location.
