Data are mean values ± SE (n = 4). Different lowercase letters denote significant differences at different sites of the same variety at the 0.05 probability level according to the LSD test. IIY838 and IIY416 indicate IIyou838 and IIyou416, respectively. GD and YA indicate Guidong and Yongan, respectively.
