ABSTRACT

DP 444 BGRR is an early season cotton variety that has performed well in experiments across central and south Alabama. This variety exhibits an anomaly that results in a split terminal. An experiment was conducted in north Alabama at the Tennessee Valley Research and Extension Center to investigate the occurrence of this anomaly under dryland/irrigated conditions and under conventional/glyphosate-based herbicide systems. In the first year of this study, there was no influence of irrigation or herbicide system on the occurrence of the split terminals. The overall occurrence of the split terminal anomaly was 11.3% in the stand. Bolls taken from plants with split terminals were found to have higher turnout, lower overall lint and seed weights, and similar lint quality compared to bolls taken from normal plants.
