Mapping QTLs Regulating Morpho‐physiological Traits and Yield: Case Studies, Shortcomings and Perspectives in Drought‐stressed Maize

Mapping QTLs in drought-stressed maize

The effects of genetic variation in morpho-physiological traits (e.g. root size and architecture) on a crop's yield under drought are still poorly understood. Tuberosa et al. (pp. 941-963) present a comparative and critical review of the results and opportunities provided by QTL analysis for unravelling the cause-effects relationships among a number of morpho-physiological traits and grain yield in drought-stressed maize.
