چکیده

Abstract The most commonly used method to control wheat powdery mildew is by fungicides. aim of the present study determine duration fungicide activity three fungicides: azoxystrobin; triadimenol; tebuconazole+spiroxamine+triadimenol. They were applied in concentrations phenophase 3-4 leaf susceptible variety. After treatment, each day one pot tested was inoculated with Blumeria graminis f. sp. tritici. When using azoxystrobin at 0.2%, 0.4%, 0.8%, symptoms appeared on plants f.sp. tritici next after treatment. triadimenol, first pathogen applying a concentration 0.12%, second 0.25% and third treatment 0.5%. With tebuconazole+spiroxamine+triadimenol, postules 0.15%, 13th 0.3% 14th 0.6%. This 0.6% (13 days) (12 has longest activity.

Competitive Performance of Transgenic Wheat Resistant to Powdery Mildew

Genetically modified (GM) plants offer an ideal model system to study the influence of single genes that confer constitutive resistance to pathogens on the ecological behaviour of plants. We used phytometers to study competitive interactions between GM lines of spring wheat Triticum aestivum carrying such genes and control lines. We hypothesized that competitive performance of GM lines would be...

Powdery mildew resistance genes in wheat: verification of STS markers.

Five accessions of Aegilops speltoides and 67 European wheat cultivars (winter and spring) originating from the Czech Republic, Germany, Poland, Russia, Slovakia, United Kingdom, and 4 non-European wheat cultivars from Brazil and the USA were examined with molecular Sequence Tagged Site (STS) markers for resistance genes to powdery mildew: Pm 1, Pm 2, Pm 3 and Pm 13. All markers gave clear, rep...

A major gene for powdery mildew resistance transferred to common wheat from wild einkorn wheat.

ABSTRACT A major gene for resistance to wheat powdery mildew (Blumeria graminis f. sp. tritici = Erysiphe graminis f. sp. tritici) has been successfully transferred into hexaploid common wheat (Triticum aestivum, 2n = 6x = 42, AABBDD) from wild einkorn wheat (Triticum monococcum subsp. aegilopoides, 2n = 2x = 14, AA). NC96BGTA5 is a germ plasm line with the pedigree Saluda x 3/PI427662. The res...
