Wheat is one of the high-value major crops in the world. However, wheat stem rust is considered one of the determinant threats to wheat production in Ethiopia and the world. So this study was conducted to assess the disease intensity, seasonal distribution dynamics pattern , the genetic variability of Puccinia graminis f. sp. tritici, and to determ...

Wheat stem rust (black rust) is one of the most important airborne diseases of wheat (Triticum aestivum) caused by Puccinia graminis f. sp. tritici remains a constraint to the world's wheat production. Because of the sudden changes in stem rust race patterns, commercial varieties tend to become vulnerable globally at large and particularly in Ethio...

AB S T RA C T Stem rust (black rust) caused by Puccinia graminis f.sp. tritici is one of the most important air borne diseases of wheat (Triticum aestivum) which causes considerable yield losses in the world, including Ethiopia. The pathogen is capable to produce new physiological races that attack resistant varieties and develop epidemic under opt...

Article Info Wheat stem rust (black rust) is caused by Puccinia graminis f. sp. tritici remains one of the most production constraints in all wheat growing areas of the country and worldwide, causing yield losses of up to 100% during epidemic years. Behaviorally, the pathogen have capacity to blow aerially long distances, fast reproduction of infec...

Wheat is one of the high value important major crops of the globe. However, wheat stem rust is considered one of the determinant threats to wheat production in Ethiopia and the globe. So this study was conducted with the objective to assess disease intensity, seasonal distribution dynamics, and genetic variability and to determine virulence spectru...

Stem rust caused by Puccinia graminis f. sp. tritici (Pgt) is one of the most important diseases of wheat in Ethiopia. It has a reputation to cause yield losses reaching up to 100% on susceptible cultivars. A study was conducted to evaluate the infection responses of 34 bread and 20 durum wheat lines at the seedling stage against four major stem ru...

Turcicum leaf blight (Exserohilum turcicum), TLB, is a major disease affecting maize (Zea mays) in western Ethiopia. The aims of this study wereto: evaluate maize varieties and propiconazole spray frequencies on epidemics of TLB, determine optimum propiconazole (tilt 250 EC) spray frequency for integrated management of TLB, and assess the cost/b...

Lack of durable resistance in bread wheat cultivars is the main reason for stem rust epidemic which could limit yields in Ethiopia. The present study was conducted to evaluate slow rusting resistance to stem rust among bread wheat cultivars. Twenty-four bread wheat cultivars along with the susceptible check were tested for their seedling and adult...

Field-based adult plant resistance assessment at multi-location rust hot spot sites is a crucial job for those plant pathologists screening several wheat lines at a time against the rusts. Rust-resistant bread wheat genotypes that have been extracted from previous studies have sustained wheat production in Ethiopia. The objective of this study was...

Ethiopia is the second largest producer of wheat in sub-Saharan Africa although yields remain considerably below the global average due to several production constraints. The aim of the study was to identify the primary threats to wheat production, farmers’ selection criteria for wheat varieties, and disease management practices with emphasis on wh...

Bread wheat genotypes with slow rusting stem rust resistance were crossed in a half-diallel mating design to identify superior parents for stem rust resistance combined with high grain yield (GY) and related traits. Significant mid-parent heterosis for area under disease progress (AUDPC) was observed in crosses 7041-1 × Danda’a and Danda’a × Kubsa....

The emergence and rapid spread of virulent races of wheat stem rust has driven a search for sources of resistance for durable resistance breeding. This study was carried out to identify possible sources of stem rust resistance between Ethiopian wheat lines. Two hundred and fifty-two wheat accessions and a universal suscept, cultivar Morocco were ev...
