“…This reflects that maize breeding was fairly successful during the past six decades in improving resistance against biotic and abiotic stresses. However, testcrosses of some landraces reached the level of the checks for these traits and it cannot be ruled out that the resistance mechanisms prevalent in these landraces differ from those typically exploited in modern cultivars (Newton et al, 2010). Strigens et al (2013) reported similar findings for DH lines extracted from landraces and suggested that mining landraces by association mapping might be a rewarding avenue for further improvement of these traits.…”

“…Historically, selection has occurred at relatively narrow spatial scales and environments, resulting in a regionally heterogeneous mixture of locally-adapted landraces (traditional heirloom cultivars) [10]. Previous research on landrace fitness–defined in terms of seed yield, size, or other similarly anthropocentric attributes–has shown that landraces tend to have stable fitness in their “home” environment, but perform poorly in other environments [11]. For example, maize landraces in Mexico have clear local adaptation along altitudinal gradients, and the most fit maize population across altitudes was a mixture of landraces [12,13].…”

“…Therefore, they are adapted to local climatic conditions, cultural practices, disease and pests (Harlan 1975). During the twentieth century, landraces have often been replaced by modern cultivars contributing to the genetic stability of several crops including wheat, barley and maize (revised by Newton et al 2010). Although these modern cultivars may be higher yielding under high input systems, landraces have considerable potential under low input systems which are usually the characteristics of the Mediterranean rim.…”
