for development of pollinator parent resistant to powdery mildew disease of sugar beet, relatively resistant 14442 population was used. based on resistance index, 50 resisitant plants were selected to produce half sib family(h.s.f). after random pollination between these 50 plants, seed of h.s.f was harvesed. from these 50 plants, only 39 plants had produced enough seed. next year these h.s.f w...

the objectives of the present study were to evaluate spring wheat recombinant inbred lines (rils) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (pca) for spot blotch resistance and yield components at bhu agricultural research farm during 2010-2011. grain yield per plot was significantly and positi...

pseudomonas aeruginosa is one of the most important pathogens that causes nosocomial infections and shows high level of antibiotic resistance. integrons are one of the transposable elements in bacteria and their role in antibiotic resistance has been well demonstrated. the aim of this study was a molecular characterization of the integron genes and the determination of the resistance or sensiti...

background staphylococcus aureus is a common cause of infections among humans and animals and it is known as a community-acquired and nosocomial pathogen. most of the isolates contain lysogenic phages which are responsible for production of various virulence factors such as enterotoxins, staphylokinase, β-lysin, lipase, exfoliative toxin a and pantone-vlaentine leukociden (pvl). all staphylococ...
