Abstract:An advanced breeding stock of upland cotton, Gossypium hirsutum L., consistently showed less seed damage from Pectinophora gossypiella (Saunders) than commercial cultivars in Arizona and Puerto Rico. This stock, designated AET-5 × (45-108 × Br-2-10)- 7-69, and 2 other related stocks that also showed reduced seed damage have a complex pedigree that includes Triple Hybrid material, (G. arboretum L. X G. thurberi Tod.) X G. hirsutum. These stocks approach commercial cultivars in agronomic and fiber properties but suffer some deficiencies, particularly in fiber length and yield potential. Their level of resistance is probably not high enough to eliminate insecticide use. Therefore, the AET stocks can best be used as sources of resistance to combine with other sources in the development of improved cultivars.
