Plant breeders generally conduct the selection phase of their program at few locations, mainly based on geography and resource limitations. We conducted this study to identify locations that optimize genotype selection based on discriminating ability and representativeness. GGE Biplot Pattern Explorer was used to rank six test locations in Louisiana for cotton (Gossypium hirsutum L.) lint yield and fiber length using data from the 1993 to 2003 Louisiana Official Variety Trials (early and medium maturity). Biplots were generated and distances between the “ideal” and actual locations were measured. Locations with shorter distances and closer to the “ideal” location were considered more desirable test locations for the traits of interest. Each location's distance was standardized by the mean distance for each biplot. For lint yield, based on its close proximity to the “ideal” test location and low standard deviation, the most desirable selection location was St. Joseph loam. Winnsboro non-irrigated and Bossier City were not good selection locations for lint yield. For fiber length, Winnsboro irrigated was ranked 1st and St. Joseph loam was ranked 3rd. Winnsboro non-irrigated was ranked 6th. A composite distance, reflecting the distance between the actual and “ideal” location for lint yield weighted at 60% and fiber length weighted at 40% was used to determine the desirability of test locations based on simultaneous selection for yield and fiber length. St. Joseph loam ranked 1st, Winnsboro irrigated ranked 2nd, and Winnsboro non-irrigated ranked 6th. St. Joseph loam or Winnsboro irrigated should be used for selecting cultivars for lint yield and fiber length. Winnsboro non-irrigated should not be used for selecting cultivars due to its low level of discrimination and unique behavior.
