Variation over time and environments in resistance to Erysiphe graminis hordei in samples from a barley germplasm collection


When germplasm is evaluated over a period of time and a range of environments, there is a danger that the basis of evaluation will change. The extent of such variation in samples from a germplasm collection was assessed using powdery mildew resistance in barley as an example. The changes found are believed to be representative of those commonly encountered… (More)
