2023 Abstract-CHANGES IN SEED SIZE AND YIELD COMPONENTS IN ARKANSAS COTTON OVER 20 YEARS: Small changes in genetically controlled yield components can affect the magnitude and stability of lint yield produced. Data for lint percentage, seed index (weight of 100 seed), lint index (weight of lint from 100 seed), number of seeds per acre, number of fibers per seed, and fiber density (number of fibers per unit area of seed coat) have been collected from variety and strain tests for over 20 years. Over time, lint index and lint percentage have increased while seed index has declined. Changes associated with each these yield components and their relationships with lint yield will be presented.
