3. Results
All fibre quality measures had significant associations with lint yield in both data sets, being consistently negative for fibre length and strength, but more variable for micronaire, fineness and maturity (Table 2).
3.1. Fibre length
Fig. 1 shows the negative association between HVI fibre length and yield across years for US and AUS data.
The relationship had significantly different intercepts (P < 0.001) with the same slope for each year in each country ( Table 2).
