| Abstract: | Several cycles germplasm from 2 Tropical populations of Pool 16 and Pool 18 were used in 3 water regimes during maize flowering period: They are well watered, intermediate water stress and severe water stress, respectively. The relationship between Grain yield (GY) and Anthesis silking interval (ASI) and other plant characteristics was studied. The results showed that: The correlation between GY and ASI increased as the stress degree increased. The correlation coefficient r=-0.529 ** under severe water stress condition; Grain yield showed significant positive correlation with ears per plant (EPP) under stress conditions. ASI and EPP can be used as main index in the germplasm selection for stress tolerance. |
