In the hot environment of Maricopa, SJ-U86 yields slightly less than its heat-tolerant parent, SG 248 (2071 kg ha^sup -1^), but with significant improvement in almost all fiber quality traits This combination of heat resistance similar to SG 248 with fiber quality that matches Maxxa and Phytogen 72 suggests that SJ-U86 could be a source of improved heat resistance for California cottons. Small quantities of seed (25-50 g) are available to cotton breeders, geneticists, and other research personnel on written request to the corresponding author or R.G. Cantrell, and will remain available for at least 5 yr. Requests for seed from outside the USA must be accompanied by an import permit allowing entry into the requestor's country.
