The term, "high glanding" (HG), refers to cotton genotypes that have pigment glands distributed throughout the calyx, including the calyx crown. This trait has been demonstrated to confer resistance to the bollworm/tobacco budworm complex (BW/TBW). The trait was initially discovered in a wild Gossypium hirsutum collected in 1957 from Socorro Island by R. Moran. Through the sustained efforts of several breeders and entomologists, the trait has been transferred to a family of strains that are exceptionally high yielding and have high fiber quality. Jacob Hartz Seed Company, under a licensing agreement with the originator, the Louisiana Agricultural Experiment Station, will market three HG varieties (currently tested as HX 1215, HX 1220, and HX 1244) beginning in 1994. These varieties were among the highest yielding in state variety tests in Arkansas, Louisiana, and Mississippi in 1992 and 1993. They have fiber length and strength equal to, or higher than 'DES 119'. In addition, they have shown a significant level of BW/TBW resistance compared to non-HG strains and varieties. Unlike early HG germplasm lines, which have 2 times the normal level of seed gossypol, the new varieties have less than 50% higher seed gossypol content than conventional varieties. Future breeding should aim at further reducing excessive seed gossypol levels while maintaining the beneficial distribution of glands on the calyx crown, a primary feeding site of young BW/TBW.
