A field experiment including fifty barley (Hordeum vulgare L.) genotypes from different sources selected from local and exotic materi­als was conducted as Preliminary Screening Nursery (PSN) at five loca­tions in the North Coastal area. Each entry was planted in four-row plot with two replications. The other experiment named Local Barley Yield Trial (LBYT) including 24 barley genotypes was grown at three locations in the Northwest coast and two locations in North Sinai under rainfed condition in 1994/95 growing season. Each entry was planted in six-row plots with three replications. In addition to these two experiments, eight advanced barley genotypes which have been selected a year before from LBYT for being high drought tolerant and stable in production under low rainfed areas were grown in a field experiment, Advanced Barley Yield Traial (ABYT), in larger scale at five locations in the North Coastal area under rainfed condition. Results showed that in the first experiment (PSN), none of the genotypes in this experiment exceeded the old check, G.123 or the new check, G.125 in GY significantly. However, three high yielding genotypes with high stability of production under different envi­ronments were identified in each of LBYT and ABYT experiments. Giza 126, the new drought tolerant cultivar proved to be superior in GY, BY, SY, and exhibited wide adaptability across different environments under rainfed conditions. In general, it seems that high grain yielding geno­types, to a large extent, give high biomass or straw which is a favorable product to farmers (Bedouins) that can be used as forage or as animal feed or grazing especially during severe droughty seasons. These results are encouraging to the breeders, not only to develop high yielding barley cultivars, but also for high adaptability under wide range of environments to maintain stability of production under these very unpredictable condi­tions.
