Prevalence and Geographic Distribution of Resistance to Crown Rust in Avena sterilis. I. Wahl , Division of Mycology and Plant Pathology, the Tel-Aviv University, Israel. Phytopathology 60:746-749. Accepted for publication 1 October 1969. DOI: 10.1094/Phyto-60-746.

Both seedling and adult plant resistance to the race group 264-276 of Puccinia coronata avenae were prevalent and widespread in populations of Avena sterilis in Israel. Seedling and adult plant resistance were found in about 32% of the oats collected in 446 locations. Though resistance to crown rust is widespread, the frequency of its occurrence in different regions varies considerably. Seedling as well as adult plant resistance was common in the Plateau of Menashe, Coast of Carmel, Mt. Carmel, Haifa Bay, and the northern portion of the Central Coastal Plain. In the southern regions, resistant plants were less prevalent.
