Abstract
Twenty one wheat genotypes including sixteen bread wheat promising lines, wheat cultivar Morocco (check for rust resistance) as a highly susceptible cultivar for rust diseases and four commercial wheat cultivars, i.e. Giza 168, Gemmeiza 11, Sids 12 and Shandweel 1 (checks for agronomic characters) were evaluated against rust diseases, i.e. leaf rust (Puccinia triticina), stem rust (Puccinia graminis f.sp. tritici) and stripe rust (Puccinia striiformis f.sp. tritici) at the farm of the Faculty of Agriculture, Minufiya University, Shibin El-Kom and at Itay El-Baroud Agricultural Research Station, during 2012/13 and 2013/14 growing seasons. Also, some other agronomic traits, i.e. days to heading and maturity, plant
height, number of spikes per square meter, number of kernel/spike, 1000 kernel weight, straw yield, grain yield and biological yield, were studied. Out of sixteen lines, seven lines, i.e. 1, 2, 7, 8, 10, 11 and 15, were found to be resistant to rust diseases and showed acceptable/desirable relative resistance index (RRI) during the two seasons. Meanwhile, wheat lines 3, 6, 9, 11, 12, 13 and 14 showed high yield at the two locations during 2012/13 growing season. Wheat line 11 was not only resistant to rust diseases but also high yielding genotype. So, this line could be recommended to be grown as a commercial cultivar at these locations which was resistant and high yielding genotype.
