Drought and low nitrogen are major stresses for maize (Zea mays L.), and maize populations from the Sahara Desert are potential sources of stress tolerance. The objectives were to assess the tolerance and varietal and heterosis effects of Algerian populations under no-nitrogen fertilization and water stress. A diallel among six Algerian maize population was evaluated under drought (300 mm irrigation) vs. control (600 mm) and no-nitrogen fertilization vs. 120 kh ha−1 N fertilization. Genotypes showed significant differences and genetic effects for water- and nitrogen-stress tolerance. We propose a reciprocal recurrent selection to take advantage of additive and non-additive effects, using AOR and IGS, since they showed good performance in optimum and stress conditions, for improving yield heterosis for AOR × IGS. Negative effects are not expected on plant height, anthesis–silking interval or early vigor. These populations and BAH could be sources of inbred lines tolerant to drought and no-nitrogen fertilization. There was no relationship between origin and genetic group and stress tolerance per se or as parents of tolerant crosses. These populations and crosses could be used as base material among Algerian populations, for breeding programs focusing on tolerance to water or nitrogen stress.

Significant Difference

Aims: Maize (Zea mays L.) is a major staple food for millions of people in Côte d’Ivoire. Due                         to its high productivity and low cost of calorie it is preferred crop for food security of the                      country. Thus, this study was conducted to assess nutritive quality of maize produced and               stocked in five purposively selected regions of Côte d’Ivoire which represents five agroecological settings. Study Design: A total of 1500 samples of maize as grains, epis and spathes were collected at rate of 500 samples by region (Gbêkê, Poro, Hambol, Indénié-Djuablin and Gontougo) and sent to the laboratory in order to analyse their nutritional quality. Place and Duration of Study: This study was carried out during March 2016 to January 2017. The collected sample were carried out at the laboratory unit of Food Sciences and Biochemistry of the Félix Houphouët-Boigny University, Abidjan. Methodology: Proximate analyses were carried out using standard methods AOAC (2000). Results: The results show significant difference from the biochemical compositions of maize type and region. Mean value intervals were as follow: dry matter (85.83 – 91.42%), ash (1.19 - 2%), proteins (7.99 - 9.32), lipids (3.21 - 4.47), carbohydrates (71.80 - 77.94), starches (62.30 - 68.44%), fibers (5.03 - 5.83%), total sugars (2,13 - 2.99%), reducing sugars (0.33 - 0.66%), free fat acidity (1.86- 4.50%), peroxide value (1.34 - 3.07 meq O2/kg), iodine value (100.93 - 130.56 g I2/100 g), unsaponifiable (0.89 - 1.54%) and energy values (357.88 - 374.39 kcal). Conclusion: A significant variability from one region to another can be noticed at level of maize quality regardless the type of maize. The nutritive quality of maize seems to be tied to postharvest treatments (drying), type of storage (epis, grains and spathes) and structure of storage.
