Assessment of Nitrogen Use Efficiency in Algerian Saharan Maize Populations for Tolerance under Drought and No-Nitrogen Stresses

Increasing drought incidence and infertile soils require the improvement of maize for nitrogen use efficiency (NUE) under conditions. The objectives were to assess tolerance genetic effects Algerian populations no-nitrogen water stress. We evaluated a diallel among six vs. 120 kg/ha N fertilization control. Variability was significant their crosses NUE drought. Additive could be capitalized using BAH MST, with high grain utilization (NUtE). most promising SHH × AOR supply both regimes NUtE, IGS, stress partial factor productivity (PFP), well-watered conditions protein content; IZM agronomic (AE) stress; nutrient (NUtE) nitrogen. These parents developing drought-tolerant or/and low hybrids improve these traits. Maximum heterosis exploited those crosses. Reciprocal recurrent selection used take advantage additive non-additive gene found based on estimations parameters.
