highly significantp -value < 0.01
In the present study under the WS condition, positive and significant correlations between certain stalk-related traits (CL, CD, IL, and SCW) and CY were similar to the NS condition in both plant cane ( Table 1 ) and ratoon cane ( Table 2 ), except for the correlation between NMC and CY, which had a highly significant correlation ( p -value < 0.01) in both plant cane ( r = 0.50) and ratoon cane ( r = 0.77) evaluated under the WS experiment but not under the NS experiment.
