Abstract

In this study an attempt is made to study agronomic characters of adaptation to drought in yield and its composants under dry land and in irrigated conditions:25 barley varieties ( 16 of French origin, 7 of Syrian origin and 2 of Algerian origin ), 1 variety of durum wheat ( DURELLE, Fance) and 1 variety of triticale (CLERCAL, France)were compared during two successive years 2003/2004. A net effect on most agronomic characters was noticed, with the exception of the thousand –kernel weight in the second year trial. The moderate water defi cit ( conditions in the Ouest Algerian zone) allowed French varieties to perform better in both conditions than Algerian and Syrian varieties because they are considered to be tolerante to drought.
