Sixteen bread wheat genotypes were evaluated for days to 50% heading, plant height, 1000-grain weight, grain yield and biological yield under six varied environments which are the combination between, two seasons 2009/2010 and 2010/2011 and three nitrogen fertilizer levels (50, 80 and 110 kg N/fad.). The combined analyses of variance showed highly significant differences were registered between genotypes, environments as well as G x E for all studied traits. Low nitrogen stress significantly reduced these traits for all wheat genotypes under 1^st and 2^nd compared with the 3^rd level. Joint regression analysis of variance revealed highly significant G x E “linear" for all characters. Environment + Genotype x Environment (E + G x E), Environment (linear) and G x E (linear) were highly significant for all studied characters. Phenotypic stability parameters revealed that wheat genotypes, Gemmeiza 7 was highly adapted to favorable environments for days to 50% heading and 1000-grain weight; Gemmeiza 9 for plant height, grain yield and biological yield; Misr1 and Line1 for grain yield and biological yield. Genotypic stability parameters indicated that wheat genotypes Gemmeiza 9 was highly adapted to favorable environments for plant height, 1000-grain weight, grain yield and biological yield; Giza 168, Line 1 and Misr 1 for grain yield and biological yield and Line 7 for plant height and 1000-grain weight. The AMMI analysis of variance showed highly significant difference between genotypes, environments, G x E, IPCA1 and IPCA2. AMMI stability value (ASV) and GE biplot revealed that, the most desired and stable genotypes were Sakha 93, Gemmeiza 7 and Line 8 for days to 50% heading; Line 8, Line 2, Sids1 and Gemmeiza 9 for plant height; Gemmeiza 9, Sids 1, Gemmeiza 7 and Line 4 for 1000-grain weight; Line1, Gemmeiza 10, Giza 168, Sakha 94 and Line 3 for grain yield and Giza 168, Gemmeiza 9, Line1, Misr1 and Gemmeiza 10 for biological yield. According to GGE biplots, the ideal genotype was Gemmeiza 7 for days to 50% heading; Gemmeiza 10 for plant height; line 7 for 1000-grain weight; Giza 168 for grain yield and Misr 1 for biological yield.
