    OBSERVATIONS. Diagram the conidiophores and conidia seen on the diseased leaf. In the table below, record the location of conidiophores, the type of conidia formation, the number of asci per chasmothecium, and a description of the appendages found on the chasmothecium. Using this information, determine the pathogen genus for each powdery mildew. Summary. Progenies of Malus robusta(Al42/5), M. zumi(A/14, A/24) and Klon 40 (Goldparmäne open-pollinated) as well as those between varieties were evaluated for natural mildew (Podosphaera leucotricha) incidence for up to 10 years in the progenies from all resistance sources field resistant plants could be found. M. robusta and M. zumi transmitted resistance better than Klon
