The effect of drought stress on (a) and (b) relative water content, RWC (c) and (d) chlorophyll content index, CCI (e) and (f) quantum yield of PSII photochemistry, FV/FM in parental lines and the F4 segregating population. Data represent mean values ± standard error. DS, drought-stressed conditions; WW, well-watered conditions. * = Significant at p = 0.05, ** = Significant at p = 0.01. Arrow Irrigation was resumed at 74 DAS
