We compared the yield performances of three American Pima cotton cultivars ( Gossypium barbadense L.), a doubled haploid from each of the three cultivars, and a composite of the three doubled haploids. The relative yields and yield stabilities of the three doubled haploids were similar to the relative yields and yield stabilities of the cultivars from which the doubled haploids were derived. The probable increased homozygosity and homogeneity of the doubled haploids did not influence yield stability. The greatest yield stability was obtained from a composite of the doubled haploids.
