Description	Breeding for improved drought tolerance is one of the most important tasks maize breeders are currently confronted with. To simplify procedures used in the conventional selection, various photosynthetic parameters have been proposed to serve as secondary selection traits for such assessment. However, even if drought-tolerant genotypes are selected by such screening, it is not known whether this tolerance will be transmited to their progeny. We have examined whether the photosynthetic parameters could be used not only for the selection of drought-tolerant inbred lines of maize but also as predictors for the heritability of such tolerance. 15 maize inbreds and F1 hybrids were grown under two irrigation regimes: continuous water supply or water supply withholded for up to 14 days; at the beginning of drought treatment, plants were at V3 developmental stage. Water use efficiency, net photosynthetic rate, chlorophyll fluorescence parameters and content of photosynthetic pigments were analyzed together wit Breeding for improved drought tolerance is one of the most important tasks maize breeders are currently confronted with.
