| Abstract | ||
| One hundred twenty three wheat genotypes derived from the International Maize and Wheat Improvement Centre (CIMMYT) were evaluated against leaf rust (Puccinia triticina) and stem rust (Puccinia graminis f.sp. tritici) as well as grain yield (1000 kernel weight and spike weight) at Gemmeiza Research Station during 2012/13 and 2013/14 growing seasons. Forty six and fifty nine wheat genotypes out of one hundred twenty three were resistant to leaf and stem rust diseases during 2012/13 growing season. While forty eight and sixty seven genotypes showed resistant reactions to both leaf and stem rusts during 2013/14. Regarding to 1000 kernel weight (g), 23 and 20 genotypes showed high yield during 2012/13 and 2013/14 growing seasons, respectively. Wheat genotypes No. 8, 31, 39, 40, 72, 80, 101 and 123 were resistant to leaf and stem rust diseases during the two successive seasons and showed high yield, these genotypes displayed various levels of adult plant resistance in the field and could be used as an important source for breeding high yielding resistant varieties. | ||
