Opis:: A collection of common wheat cullivars grown in Poland were analyzed for resistance to powdery mildew disease by using eleven differential isolates of Erysiphe graminis f. sp. tritici (Blumeria graminis). Among a total of 69 accessions, 48 cultivars possessed resistance which is attributed to known resistance genes present either individually or in a combination. Four cultivars were resistant to all the isolates used and another four cultivars revealed race-specific resistance which does not correspond to the response patterns of previously documented resistance. Resistance genes Pm2 and Pm6 in a combination were most widely distributed, and genes Pm3d, Pm4b, Pm5 and Pm8 were also postulated.

Opis:: The Mediterranean flour moth, Ephestia kuehniella Zeller, is a major pest of stored grain products, particularly flour. There have been major concerns over the application of conventional insecticides in stored products, which have strongly demonstrated the need for applying such alternative safe compounds as essential oils. The aim of the present study is to investigate the chemical composition and fumigant toxicity of essential oil from Ziziphora clinopodioides Lam. against the eggs, larvae, and adults of E. kuehniella. All toxicity tests were carried out under laboratory conditions set at 26±1°C and 70% relative humidity (RH). The results of gas chromatography- -mass spectrometry (GC/MS) analysis indicated that the essential oil extracted from the leaves of Z. clinopodioides, is rich in pulegone (49.4%), piperitenone (10.7%), menthone (8.9%), and 1,8-cineol (6.9%). Based on the bioassay results, the LC50 value of the tested oil was estimated to be 54.61 μl · l–1 air for larvae and 1.39 μl · l–1 air for adults. Also, it is shown that increasing the oil concentration resulted in a significant increase in oviposition deterrency as well as a considerable reduction in the egg hatching percentage. These results suggest that Z. clinopodioides oil could be a potential candidate as a fumigant for managing E. kuehniella in stored products.

Opis:: Sixty-six wheat cultivars grown in Belarus, Poland, Russia and the Ukraine were tested for mildew response to a collection of 11 different isolates of Erysiphe graminis DC f. sp. tritici Marchal. Nineteen cultivars have shown a susceptible reaction and eighteen were characterized by susceptible or intermediate responses. Fourteen cultivars revealed isolate-specific response patterns that could be attributed to major known resistance genes or gene combinations. Twelve cultivars have one documented gene: Pm5 in eight cultivars, Pm2 in two cultivars and Pm8 also in two cultivars. One cultivar has two genes (Pm2 + Pm6), while another cultivar carries a combination of three genes (Pm1 + Pm2 + Pm6). Fifteen cultivars were characterized by response patterns not documented so far or by a known resistance response combined with an undocumented resistance. Apparently three cultivars with the T1BL.1RS wheat-rye translocation have a gene suppressing the Pm8 mildew resistance. One cultivar was resistant to all the used isolates. Its resistance might be conditioned by an unknown major gene or combination of genes.
