| Abstract |
Thirty bread wheat genotypes were evaluated for phenotypic stability in six environments i.e., three locations (Gemmeiza, Sers El-Laian and Ettai El-Baroud) and two growing seasons (2002/2003) and (2003/2004).
The results showed that:
• Highly significant differences were detected for the studied locations, years and genotypes.
• All types of studied interactions were highly significant i.e., years x locations, years x genotypes, locations x genotypes and years x locations x genotypes.
• The earliest genotypes were the numbers 2, 8 and 11 for all studied locations and their average.
• The promising varieties, Gemmeiza 9, Giza 168 and Sakha 93 had the highest numbers of spikes/m2 in all studied locations and their average.
• Genotype number 4 had the highest number of grains/spike in two locations i.e., Gemmeiza and Sers El-Laian while the variety Gem.9 behave so in Ettai El-Baroud.
• The results showed that the genotype number 2 had the heaviest grains in all locations and their average.
• The results confirmed that the new varieties Gem.9, Giza 168 and Sakha 93 in addition to Gem.5 are the best for grain yield (ard./fad.) although these varieties did not had the highest values for the traits; number of grains/spike and 1000-grain weight. On the other hand, these results confirmed the importance of number of spikes/m2 in increasing grain yield in wheat that it is a major component for grain yield. Also these varieties showed good phenotypic stability
