| Abstract | ||||
| In Algeria, barley cultivation comes after wheat cultivation. Low rainfall and high temperature affected barley yield. This experiment consists of evaluating the parameters of 16 local barley cultivars in our semi-arid conditions. Two experiments were carried out at the INRAA experimental station (Hmadna) in the Bas-Cheliff plain, for two years 2017/2018 and 2018/2019. The parameters studied are: the height of the plant, the length of the edges, the length of the ears, the ears per square meter, the grains per ear, the biological yield, the grain yield, the weight of a thousand grains, the harvest index, straw yield and cycle. The results showed greater variability between genotypes on parameters (plant height, ear length, biological yield, grain yield and straw yield). The first season divided the cultivars into two groups, the second season assembled the cultivars into four groups. Also, the cultivars expressed a better adaptation and kept the best values of the yield parameters (grains per cob, thousand grain weight, grain yield, organic and straw yields). Genotypes 12, 15, 16, 17, 18, 25, the control Saida (23) was almost late, except for the two-row genotype 14. Also, the great utility of variability between cultivars, 14 and two controls, 07 cultivars behaved well in our difficult climate and soil conditions | ||||
