Abstract

Fineness and maturity measures were compared on two groups of cotton samples tested with the Micronaire, Arealometer, and IIC-Shirley fineness/maturity tester; one group was also tested with the Causticaire and sodium hydroxide maturity methods. Most correlations of the various parameters were high for Group A samples composed of four cultivars of Gossypium hirsutum L. The correlations were usually lower for Group B, which was made up of three species and several cultivars. Comparable parameters from different instruments were not always on the same level because of different calibration standards and procedures. However, if the correlation between methods is high, one can move from one measurement to another with a regression equation.
