“…Most of the wheat cultivars currently recommended in northern New South Wales and Queensland, Australia, possess different levels of APR to stripe rust. This resistance is in many cases believed to have been derived from introductions from the international Maize and Wheat Improvement Centre (CIMM YT), Mexico (Syme & Thompson, 1986). Little is known about the diversity and genetic control ofthe APR present in these wheats, and increasing reliance is now being placed on this type of resistance in cultivars • Prescnl uddress: The University of Sydney, Pliint Breeding Institute, PO Box IKO.Castle Mill, NSW 2154, Australia grown in eastern Australia.…”

The onset of adult plant resistance (APR) to Puccinia striiformis was examined in seven Australian wheat cultivars under field conditions and in 14 cultivars under controlled environmental conditions. In most cultivars under field conditions the percentage leaf area affected by stripe rust at mid‐tillering (GS 22–26; third leaf) was significantly less (P < 0.05) than on the more susceptible cultivar Teal. The expression of APR was more conspicuous during tillering to node formation; at these growth stages chlorosis and/or necrosis developed in association with rust colonies on the most resistant cultivars. Under controlled conditions, the primary leaves of all cultivars except Olympic and Flinders displayed some resistance when compared with Teal (lower infection types, longer latent periods and/or less percentage leaf area affected). Studies on the spread of stripe rust from infection foci established in selected cultivars in the field indicated that the resistance detected at early growth stages in Suneca in controlled environmental studies also appeared to be effective in the field.

Effects of early and full season epidemics by stripe rust (Puccinia striiformis f. sp. Tritici) were examined in 12 wheat cultivars with different levels of adult plant resistance (APR). The APR in Cook, Bass, Banks, Kite, and Suneca was generally effective in preventing detectable yield losses due to stripe rust infection. Cultivars with lower levels of APR experienced yield losses of 15-25%, compared with 45-50% reduction for the susceptible cultivar Teal. Severe stripe rust infection early in the season, prior to node formation, resulted in significant yield reductions only in the more susceptible cultivars. Yield reductions were usually associated with reduced grain weight, and no reduction in tillering was detected in diseased plants. Severe stripe rust infection did not significantly affect the concentration of grain phosphorus, but did result in reduced grain nitrogen concentration in the more susceptible cultivars.
