Table 1 Chlorophyll Concentration (FW, mg•g−1) in canopy leaves with10 replicates were measured with SPAD-502(Minolta Camera Co. Ltd., Japan) at different growth stages, then use the SPAD vs actual chlorophyll content calibration for cv. YLY1 and LYP9 respectively in 2014 and 2015.TS means tillering stage, PDS means panicle differentiation stage, MS means Milk stage of grain filling, YRS means yellow ripe stage
