Gossypol concentration of flower buds (squares) from selected medium to high gossypol lines of upland cotton, Gossypium hirsutum L., was studied both in greenhouse and field conditions. Gossypol concentration of 20‐day‐old squares generally rose and fell during the growing period. Two cycles of fluctuation occurred in a high gossypol line. The gossypol concentration was independent of square size in the high gossypol line, but was negatively correlated with square size in four medium gossypol lines. Gossypol concentration of squares from greenhouse‐grown plants were strongly correlated with those of squares from plants of the same genotype grown in the field. Samples of 3 to 5 squares/plant, collected during the same 12‐day interval, gave reliable comparisons of the relative gossypol concentration of all lines tested.
