Descripción
In the Argentinean Andean region, maize is a main staple being cropped up to27 3900 meters above the sea level. Yields are limited by the sharp decrease in temperature28 associated with altitude but also by a lack of management and breeding technologies to29 underpin traditional practices. In this review we discuss (i) the main physiological changes30 of increasing altitude using experimental reports up to 2650 meters above the sea level31 (masl) plus own experiments up to 3300 masl; (ii) available genetic diversity within local32 races; (iii) maize cropping systems based on literature and own data from 23 surveys; and33 (iv) possible avenues for improving yield. Among physiological traits, major penalties are34 associated with delayed phenology reducing light capture, and low temperatures inhibiting35 photosynthesis and kernel growth rate. As a result, yields can be reduced up to 85% at36 3300 masl compared with 2300 masl in contrast to increases at lower latitudes. Local races37 are characterized by a high genetic diversity that is aiming to be preserved by both in situ38 and ex situ conservation initiatives. However, little is known about phenotypic variation,39 impairing the exploitation of these genetic resources in breeding programs. Breeding40 strategies could consider tillering ability (to buffer stand heterogeneity) and41 photosynthetic recovery rates from chilling as important target traits, whereas plant42 density management could overcome penalties related with delayed plantings and43 phenology. Water availability is currently insufficient, especially at higher altitudes where44 most farmers rely on water from thaw, and climate change projections suggest this will45 worsen; thus improving water use efficiency also deserves further work.
