The influential AUS years were 2004,
which had a wide range of micronaire 3.5–4.5 and high lint yields; 2005,
which was lower yielding - seen in the cluster at approximately 2300 kg/ha and about 4.5 micronaire; and 2007 with lower micronaire values and a range of yield.
However the most influential data were the Acala cultivars; by omitting them from the dataset the slopes became equal with a positive average slope of 0.00371 ± 0.00006 micronaire units/kg/ha (not shown).
