  1. Mean, standard deviation (STD), minimum (Min), maximum (Max), heritability (h 2) and significance of the variance between RAC875/Kukri DH lines (F-test) for the traits phenotyped under field (Lameroo, Roseworthy), well-watered (WW) and drought (D) glasshouse conditions. **, * and ns are p < 0.01, p < 0.05 and not-significant, respectively
