AbstractFive experimental strains, P65, P67, P64 P69, P70, and pima S-6 were grown in 9 regional tests across the pima belt in 1988. Mean yields from the 9 locations showed that P67 averaged highest in yield followed by P69, P70, P65, P68 and pima S-6 respectively. The difference in mean yield between P67, the highest yielding entry, and pima S-6 was 82 pounds of lint per acre. Pima S-6 was the latest maturing and tallest entry in the regional test at Maricopa. The 5 experimental strains had longer, finer, and whiter fiber than pima S-6.

Lint Yield of Several Cotton Varieties Planted on 5 Dates at 3 Locations in Arizona in 1986Kittock, D. L.; Hofmann, W. C. (College of Agriculture, University of Arizona (Tucson, AZ), 1987-03)There were some wide variations in cotton variety performance at five planting dates among locations and years. However, on an average, DP 90 and DP 77 performed best when planted between 28 March and 24 April. Stoneville 506 and DP 50 averaged best for May plantings and DP 20, Stoneville 112, and DP 50 averaged best for early June plantings.
