GEMMEIZA 11 – A NEW EGYPTIAN HIGH YIELDING BREAD WHEAT (Triticum aestivum L.) CULTIVAR

The newly bread wheat cultivar Gemmeiza 11 has been selected from a local cross made at Gemmeiza Agricultural Research Station, Wheat Research Dept. FCRI, ARC. Egypt, using the pedigree method. Yield evaluation was performed through 10 preliminary yield trials in 2005/ 2006, 65 advanced yield trials in 2006/2007 and 2007/2008 growing seasons, 66 verification yield trials in 2009/2010, 2010/2011 and 2011/2012 seasons  in addition to 106 demonstration  fields in 2011/ 2012 growing season. Results proved the superiority of the new bread wheat cultivar Gemmeiza11 compared to the commercial  check cultivars  Sakha 93, Sakha 94, Gemmeiza 9 and Shandaweel 1 in the most of different zones with a few exceptions . However, at the level of over all mean of the check cultivars across the locations at different climatic zones, the new cultivar mean yield exceeded significantly all the check cultivars means in both 2006/2007 and 2007/2008 growing seasons. Thus, we can highly recommend the new cultivar Gemmeiza 11 to be grown all over zones of Egypt. Moreover, the results of the verification yield trials ensure the superiority of Gemmeiza11 on the commercial wheat cultivars Sakha 93, Giza 168 and Gemmeiza 9 at North, Middle and South Delta, but at Middle Egypt its yield was less than the check cultivars Sakha 93 and Giza 168 and it was nearly equal at Upper Egypt. The obtained  results of  the new cultivar in the demonstration fields  achieved 28.38 ard /fed in four governorates in Middle and South Delta compared to the mean of the five  check cultivars which yielded 24.162 ard / fed with an increment of 4.128 ard / fed (17.46%).
