Host plant resistance in wheat (Triticum aestivum) has been the principal means of managing leaf rust caused by Puccinia triticina. The need for durable resistance has changed the focus from the use of seedling resistance to adult-plant resistance. The objectives of this study were to determine the genetic basis for adult-plant resistance and to determine the most effective method to identify adult-plant resistance genes Lr12, 13, and 34 among 116 contemporary soft red winter wheat cultivars and breeding lines. Adult-plant resistance was detected by inoculating flag leaves with a race that was virulent on seedlings. Approximately 90% of the lines expressed resistance under controlled conditions. It was postulated that the adult-plant resistance in 67 lines was due in part to either Lr12, 13, or 34; the adult-plant resistance detected in 17 lines was attributed to Lr12 based on a distinctive low infection type very similar to that on the isoline TcLr12; the adult-plant resistance in 27 lines was attributed to Lr34, as all of these lines expressed a “leaf tip necrosis” in the field (a phenotype controlled by a gene known to be tightly linked with Lr34); and the adult-plant resistance in 23 lines was attributed to Lr13 based on a high infection type at 18.1°C and low infection type at 25.5°C with one or more pathogen isolates that were virulent on Lr13 at 18.1°C and avirulent on Lr13 at 25.5°C. The adult-plant resistance detected in the remaining 40% of the lines was due to one or more unidentified genes for adult-plant resistance. In a 4-year field study at several locations, nearly 29% of the lines were resistant at all locations, no line was susceptible at all locations, and only 30% of the lines were susceptible at one or more locations. Given that many of the lines in this study were resistant to all known races of P. triticina before being released as cultivars, the high frequency of adult-plant resistance in this study demonstrates that adult-plant resistance can be incorporated even in the presence of highly effective seedling resistance.

Sichuan is an important wheat producing province of China where severe stripe rust epidemics occur annually. Developing high-yielding wheat varieties with good and stable stripe rust resistance is a foremost breeding objective of all breeding programs. Because minor gene based adult-plant resistance (APR) is considered durable, a shuttle breeding program between Sichuan Academy of Agricultural Sciences (SAAS) and CIMMYT was initiated in 2000 to transfer APR identified in CIMMYT wheats to wheat germplasm adapted in Sichuan. During 2007–2009, a total of 669 advanced generation lines obtained from this shuttle breeding effort were provided to the Plant Protection Research Institute, SAAS for official multi-environment stripe rust tests, and 231 elite lines were characterized for yield performance by the agronomists at the Crop Research Institute, SAAS. Between 11–39% lines were highly resistant depending on the year of testing and 17 (7.3%) lines had 5% or higher yields than the check mean. The adapted resistant lines are being used by various breeding programs to enhance resistance diversity, and three lines are being tested in National or Provincial Yield Trials for possible releases.

Stripe rust, caused by Puccinia striiformis f. sp. tritici, is an important disease of wheat in the Great Plains and southeastern United States. Growing resistant cultivars is the preferred means for managing stripe rust, but new virulence in the pathogen population overcomes some of the resistance. The objectives of this study were to characterize the stripe rust resistance in contemporary soft and hard red winter wheat cultivars, to characterize the virulence of P. striiformis f. sp. tritici isolates based on the resistances found in the cultivars, and to determine wheat breeders’ perceptions on the importance and methods for achieving stripe rust resistance. Seedlings of cultivars were susceptible to recent isolates, indicating they lacked effective all-stage resistance. However, adult-plants were resistant or susceptible depending on the isolate, indicating they had race-specific adult-plant resistance. Using isolates collected from 1990 to 2013, six major virulence patterns were identified on adult plants of twelve cultivars that were selected as adult-plant differentials. Race-specific adult-plant resistance appears to be the only effective type of resistance protecting wheat from stripe rust in eastern United States. Among wheat breeders, the importance of incorporating stripe rust resistance into cultivars ranged from high to low depending on the frequency of epidemics in their region, and most sources of stripe rust resistance were either unknown or already overcome by virulence in the pathogen population. Breeders with a high priority for stripe rust resistance made most of their selections based on adult-plant reactions in the field, whereas breeders with a low priority for resistance based selections on molecular markers for major all-stage resistance genes.
