| Wheat breeders have to determine the new cultivars and lines responsive to the environmental changes for grain yield and yield components. Therefore, this study was conducted to evaluate 20 bread wheat (Triticum aestivum L) genotypes including 9 registered cultivars and 11 promising lines for their stability grown in five different locations (EL-Gemmeiza, Sakha, Nubaria, Sids and Shandaweel Agricultural Research Station) for three growing seasons (2009-2010, 2010-2011 and 2011-2012), and to select genotypes having desirable traits to be used in twenty bread wheat genotypes. Field trials were conducted in a randomized complete block design with three replications at each location. Number of spikes per square meter, number of kernels per spike, 1000-kernel weight and grain yield of the genotypes were evaluated in each location.The AMMI analysis showed that (73.79,57.28,47.27 and 22.51%) of the total squares were due to environmental impacts (1.72, 4.96, 4.01 and 20.37) to genetic effects (13.65, 24.44, 27.76, and 32.4%) of the effects GEI on the grain yield, the number of spikes / m², number of kernels / spike and 1000- kernel weight, respectively. The genetics (GEI) were divided into three axes for the analysis of the reaction components (IPCA) of the grain yield and its components. The results showed that IPCAs were of great importance. Three IPCAs (55.77,63.76,61.45 and 67.38%) represented the interaction variation of the grain yield, the number of spikes / m 2, the number of kernels / spike and the weight of 1000 -grain, respectively. The most stable genotypes were Giza 168, G18, G13, Gemmeiza11 and G10 with high yield potential. For grain yield. The best genotypes with respect to E5 and E14 were Sids12 and Masr1. For E13, E3, E2 and E7 as well as for G20 and G 17. For E6, E1 and E15, were G11. The E4 had Sids13 and shandaweel1. E9, E11, E8 and E12 were the G12. E1, E9 and E13 were also the most distinct environments. For grain yield. The most stable genotypes were G18, G16, Masr2, G13and G20 with high production potential, For recorded Gemmeiza 11 genotypes at environments E15, E10, E8, E3, E9, E5, E13, E4 and E12. For E6, E2, E1, E7 and E11 were Sids13. It also shows that E1 and E6 are the most distinct environments. For Number of spike/m² The most stable genotypes were G19, G13, G15 Sids13and G14 with high production potential for Number of kernels/spike. The best genotype namely G20 were E7, E12, E2, E8. and G10 for E1, E13, E3 and E10. For E5, E15 and E4, they were G1. For E9, E6 and E14 were Shandaweel1. It also shows that E14, E15, E5 and E4 were the most distinctive environments. for Number of kernels/spike. The most stable genotypes were Masr2, Sids12, Sids13 G12 and G13 with high potential, The best genotypes with respect at environment number E4, E5, E7, E10, E14 and E15 were Gemmeiza11. For environment number E6 and E1were genotype number G17.At environment number E3, E19 and E13 were genotypes number G19.The best distinct environment number E1 and E9 for the 1000 kernel-weight. | ||||
