highly significantP < 0.001
Correlation coefficients for the polymer-size traits and high molecular weight fructan content were calculated using data from all three dates and were highly significant ( P < 0.001) in all cases (major peak, r = 0.733; largest peak, r = 0.693; profile regression constant, r = 0.700; profile regression slope, r = 0.658; n = 33).
