The biological and agronomic characterization of cereals constitutes a pre-liminary and essential step for the assessment of genetic diversity state which must be valued, exploited and known in a clear and complete manner in order to be able to exploit them in improvement and adaptation programs of cereals. In this context, our study was carried out during the 2018/2019 agricultural campaign on the experimental site of the technical institute of field crops ITGC of El Khroub (Constantine, Algeria). Its objective was to char-acterize the biological and agronomic diversity in two cereal species, bread wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) by evaluating many pheno-morphological, physiological and biochemical characters as well as production traits (agronomic traits). The correlation coefficients analysis between traits indicates that the short and early heading varieties which accumulate less proline are more productive than varieties which are charac-terized by long straw and late heading in both species. However, it has been noted that barley varieties reach heading before bread wheat varieties. In addition, it shows that the grain yield is positively correlated with these com-ponents, in particular with the number of seeds per ear, the number of ears per square meter, and with the following parameters: the surface of the flag leaf and its content of chlorophyll pigments, the totality of the ear character-istics such as the length of the ear neck. These results lead us to say that an indirect selection via these crops can be beneficial for the production and improvement programs of cereals.

Barley Genotypes

Barley (Hordeum vulgare L.) is an important cereal crop, but its sustainable production is significantly hampered due to the presence of various edaphic stresses. Understanding the variability in root morphological traits among diverse barley genotypes is critical for selecting those with suitable root traits for breeding new cultivars better adapted to stress environments. Root morphological traits in an early growth stage (30 days after transplanting) in a panel of 189 barley genotypes (mostly advanced breeding lines) were assessed using a semi-hydroponic phenotyping platform followed by a validation experiment of eight genotypes with contrasting root systems in two soils. The phenotyping experiment showed large variation (coefficient of variation values ≥ 0.25) in 16 of 26 measured root and shoot traits. A strong correlation among most of the selected traits was identified. Principal component analysis indicated four principal components (eigenvalues >1) captured 79.5% of the total variation. Root traits, including total root length, root length at various depths, root diameter and root length ratio (top 20 cm vs. lower section), could be considered in the barley breeding programs. Consistent ranking of the selected eight genotypes based on root biomass and root length in both the semi-hydroponic system and the columns with two different soils confirmed root trait performance in different growth environments as well as the reliability of the phenotyping method. This study identified phenotypic variability in root morphological traits in barley genotypes in the early growth stage. The genotypic variability in root traits represents a basis for mapping quantitative trait loci (QTLs) and molecular markers, particularly focused on breeding lines with optimal root properties for the efficient acquisition of soil resources and adaptation to drought and other abiotic stresses.
