A set of experiments were conducted in two Arizona locations to evaluate preliminary and advanced strains from the Arizona Cotton Growers Association breeding program. These trials were conducted in Yuma, AZ (130 ft. above MSL) and Maricopa, AZ (1170 ft. above MSL). Strains were planted into four row plots extending 38 feet in a randomized complete block design with a minimum of three replications. Each location had three commercial cotton varieties included as control treatments for comparison. Data collected on these trials included a series of plant measurements at three growth stages over the course of the season, plus yield and fiber quality data. All data were subjected to statistical analysis to test for differences among strains for yield and fiber quality. The trial conducted at Yuma performed extremely well with yields ranging from 1300 to over 2100 lbs. lint/acre. The Maricopa test site experienced some adverse weather (high levels of heat stress) and insect related conditions that led to overall decreased yields. Ranges in yield were from approximately 800 to just over 1400 lbs. lint/acre. Significant differences among lint yield and fiber properties were experienced at each location. Plant measurement results also demonstrated interesting trends among strains and locations.
