Abstract:Characters for partial resistance to mildew (Erysiphe graminis f.sp. hordei) derived from primitive barley lines were tested and found to have been transmitted to F9 progeny of crosses with the susceptible cultivar Golden Promise with varying degrees of efficiency, and putative transgressive segregation was observed. Derived sterol extracts from mildew cell walls were used, in conjunction with infection frequency data, to quantify the mildew present, and this sterol was characterized as being of MW 470, probably (3.beta)‐ergosta‐5,24(28)dienol (C31.H54.0.SI SILANE).
