Characterization of modern durum wheat genotypes (Triticum durum Desf.) for some morphological, physiological and biochemical parameters under the effect of water treatment (rainfall and irrigation) in semi-arid environments

cropwat, durum wheat, semi-arid, water efficiencyAbstract
In the semi-arid regions of the Algerian highlands, demand for irrigation water has increased due to population growth, and climate change. Irrigation and the selection of durum wheat genotypes play an essential role in the payer economy and require comparative and identification studies of new durum wheat varieties. To understand the current situation, we compared two new durum wheat genotypes with old ones on morphological, biochemical, physiological parameters, and yield components; in addition, we examined the response of the genotypes to the components of water use efficiency. In a pilot farm in a semi-arid environment in the Algerian highlands, we compared two new durum wheat genotypes with two pregnancies on different morphological, biochemical, physiological parameters and Statgraphics centurion 18 and JMP Pro 13 test yield components for two-water treatment based on cropwat software, the results obtained. The results show that the new genotypes have similar and sometimes better traits than the old ones. Boutaleb (BT), new genotype it showed better reactions on all the parameters studied, it decreased leaf area for a resistance reaction, higher biomass in rainfall as an index of sensitivity to water stress, better yield to present a production trait, as well as Boutaleb (BT) and the variety with the highest water value for both treatments. The new varieties Boutaleb (BT) and Oued el bared (OEB) reveal the existence of a great variability for most of the parameters measured, there are still other parameters to be studied for the well classified in the future.
