Aims: High maize yields in modern well-managed agroecosystems depend on the use of elite varieties and hybrids. Unfortunately, because of repeated selection at high fertilizer rates, some beneficial traits, such as the interaction with arbuscular mycorrhizal fungi or the release of organic acid anions for phosphate mobilization and for attracting beneficial microorganisms, might be gradually declining in modern elite genotypes. However, old founder lines and landraces possibly carry genetic relicts that originate from pre-green revolution times that are useful for breeding elite material for low input farming systems.

缺磷条件下燧石玉米根部菌根化和有机酸渗出：育种系和地方品种双单倍体系的趋势

目标：现代管理良好的农业生态系统中的高玉米产量取决于优良品种和杂交品种的使用。不幸的是，由于在高施肥率下的重复选择，现代优良基因型中的一些有益特性，例如与丛枝菌根真菌的相互作用或释放有机酸阴离子以动员磷酸盐和吸引有益微生物，可能会逐渐减少。然而，旧的创始人系和地方品种可能携带源自绿色革命前时代的遗传遗物，这些遗物可用于为低投入农业系统培育优良材料。
