<div><strong>Background:</strong> In Mediterranean climate, drought and heat stress are the main constraints for cereal production under rainfed conditions. In these conditions, the selection of suitable genotypes is crucial to improve production.<br />
<br />
<strong>Methods:</strong> 20 advanced triticale lines were evaluated under semi-arid conditions in Setif (Algeria) during the 2019/2020 season using agronomic, morphological and physiological traits.<br />
<br />
<strong>Result:</strong> The results obtained showed that lines with higher numbers of tillers, spikes, grains per spike, leaf area index and leaf chlorophyll content produced more grains and used water more efficiently when faced to drought and heat stress in post-anthesis phase. Also, high chlorophyll content, high relative water content and maintenance of cell membrane stability delayed senescence and extended the grain filling stage. Relative water content was also related to high grain protein content. This work evaluated this set of triticale lines and identified traits positively related to grain yield and water use efficiency in Mediterranean region.</div>

<div style="text-align: justify;">This study was conducted to determine the effects of mixture ratios and harvest times on mineral contents of forage pea &ndash; triticale mixtures hay. &nbsp;Leafed and semi-leafless pea (Pisum sativum L.) cultivars and triticale (xTriticosecale Wittmack) were sown in pure and in mixtures (75:25, 50:50, 25:75). Harvests were performed at boot and milk-dough stages of triticale. Experiments were conducted in randomized blocks design with 3 replications for 2 years. The data were subjected to ANOVA. Additionally, Pearson correlation coefficients were calculated between triticale ratios and quality parameters. &nbsp;1n the first year at both harvest times of all mixtures; while Ca, Mg and Ca/P ratios decreased with increasing triticale ratios in mixture, K/(Ca+Mg) ratio increased with increasing triticale ratios in mixture ratio. Herbage mineral contents decreased with delaying harvest. It was concluded based on animal nutrition principles that triticale ratios of the mixtures should be limited and harvest should be performed at boot stage of triticale.</div>
