The inheritance of resistance to a culture of race 8 of powdery mildew was studied in the resistant barley varieties Ottawa 5069-40 and B294. Ottawa 5069-40 possesses one dominant gene for resistance which is probably the gene from the variety Duplex. B294 possesses two dominant genes for resistance. The three resistance genes are inherited independently. No linkage was detected between the resistance genes and the genes for row number, awn type, and rachilla hair length.

The total sterol composition of conidia of the obligate plant pathogen Blumeria (= Erysiphe) graminis f.sp. tritici has been analysed as a function of their ontogeny during sporulation. Two main classes of sterols were characterized: 24-ethylsterols (24-ethylcholesta-5,22-dienol, 24-ethylcholesterol, and Δ5-avenasterol) and 24-methylsterols (24-methylenecholesterol and episterol). Our results show that sterol composition is greatly modified during ontogeny of B. graminis conidia both at the qualitative and quantitative levels. In particular, 24-methylsterols, e.g., 24-methylenecholesterol and episterol, are the major sterols in old conidia whereas 24-ethylsterols, e.g., 24-ethylcholesta-5,22-dienol, 24-ethylcholesterol, and Δ5-avenasterol, are the main sterols in young conidia.Key words: Erysiphe, wheat powdery mildew, sterols, ontogeny.
