The Texas Agricultural Experiment Station (TAES) announces the release of seven multi-adversity resistant (MAR) germplasm lines of Upland Cotton (Gossypium hirsutum L.) from the MAR-5 gene pool. The lines are designated as CABCHUS-2-86, BLLCABS-3-86, LBBCABCHUS-1-87, LBBCHU2GS-1-87, C5HUG2BES-2-87, CDP37HPIH-1-1-86, and LBBCD3H-1-87. These lines were developed by the TAES-MAR Cotton Genetic Improvement Program, utilizing specific seed, seedling, and plant selection techniques and procedures for the simultaneous genetic improvement of resistance to pests (plant pathogens and insects) and abiotic stresses, in addition to increased yield potential, earliness, and improved fiber and seed quality (3,6).
