Puccinia striiformis f.sp. tritici (Pst) is the causal agent of stripe (yellow) rust on wheat. It seriously threatens wheat production worldwide. The obligate biotrophic fungus is highly capable of producing new virulent races that can overcome resistance. Studying the inheritance of Pst virulence using the classical genetic approach was not possible until the recent discovery of its sexual sta...

Stripe (yellow) rust caused by Puccinia striiformis f.sp. tritici, is one of the major diseases wheat in world. Development and use resistant cultivars most economical environmentally friendly solution combating stripe rust. Field experiments were carried out at two sites Ethiopia (Kulumsa Meraro) seedling tests conducted KARC greenhouse during 2015 cropping season to evaluate response 192 elit...

The article calculates generalized estimates of the resistance wheat varieties grown in several regions Republic Uzbekistan to Yellow Rust, Brown and Flour Dew. In this regard, classification according their disease, latency features, calculation weight use these calculate were carried out. As a result, features played an important role assessing disease varieties, some did not play significant...

The paper presents smallholder farmers' perceptions on attributes of bread wheat varietiesbased on primary data collected from 524 households in four major wheat growing areas ofEthiopia. The results indicated high value of attainment indices for improved varieties comparedto landraces, which shows how the demanded attributes are embodied more in improved ones.Grain yield and yellow and stem ru...

We examined the correlation between sputum colour and the presence of potentially pathogenic bacteria in acute exacerbations of chronic bronchitis (AECBs). Data were pooled from six multicentre studies comparing moxifloxacin with other antimicrobials in patients with an AECB. Sputum was collected before antimicrobial therapy, and bacteria were identified by culture and Gram staining. Associatio...

the 1rs chromosome segment derived from petkus rye carries genes for resistance to three wheat rust diseases, namely lr26 for resistance to leaf rust (caused by puccinia triticina), yr9 for resistance to stripe rust (p.striiformis f. sp. tritici) and sr31 for resistance to stem rust (p. graminis f. sp. tritici). since sec-1 is tightly linked with the three rust resis-tance genes electrophoresis...
