Gemmiza 9: A new Egyptian high yielding and rust resistant bread wheat cultivar for delta region

Abstract: The three wheat rusts, stripe, stem and leaf caused by Puccinia striiformis, P. graminis and P. recondita, sequently, are the most destructive diseases that threaten wheat production in Egypt. Therefore, resistant to these rusts are very important requirement for licensing the new cultivars by National Wheat Research Program, Agricultural Research Center (ARC). Egypt has been subjected to four sever attacks form the strip rust causal agent during the last decade of the last century. This gives Egyptian wheat breeders good opportunity to develop new promising resistant cultivars and/or lines. Gemmiza 10 is one of the new wheat cultivars having high yielding potentiality and simultaneously, exhibiting high resistance to the three rusts.
A total of 156 experiments were conducted at different levels of yield trials (screening, preliminary and advanced) as well as demonstration fields during the period from 1994/1995 to 1999/2000. The obtained results proved the superiority of the new cultivar Gemmiza 9 as compared with the commercial checks Sakha 69, Giza 164, Sids 1 and Gemmiza 5 at both North and South Delta in the old and new lands. Moreover, the cultivar Gemmiza 9 expressed its highly resistance to the three rusts. On the other hand Gemmiza 9 seems to be sensitive to heat stress prevailing, sometimes in Middle Egypt and usually in Upper Egypt, during wheat growing season. Therefore, Gemmiza 9 is highly recommended to be grown and to replace the commercial cultivars Sakha 8 and/or Sakha 69 in Delta Region.
