Eight cotton varieties were evaluated at three locations for a 3-year period to estimate the magnitude of variety ✕ environment interactions. The presence of a substantial variety ✕ location ✕ year interaction for lint yield, lint percentage, and weight per boll indicated that varieties showed differential responses when grown in different environments. With the exception of fiber elongation and 50% span length, the second order interactions were larger than either of the first order interactions; however, with the exception of lint yield, the magnitude of these interactions was small in comparison with the varietal components, and thus may be considered relatively unimportant. The lack of a significant variety ✕ location or a variety ✕ year interaction for all characters measured, indicated that neither locations nor years had any consistent effects on differential variety responses.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
