[Genetic determination of stem-rust resistance in rye].
The harmful effect of stem rust on the crops of short-stem diploid winter rye was studied. If stem rust affected the plants by 70-100%, this decreased the mass of 1000 grains by about 35.8%. The genes that control the stemrust resistance of rye might originate from the following cultivars and forms: Ilmen, Orlovskii Gibrid, Kharkovskaya 55, Kharkovskaya 60, Kustovka, Kombaininyai, Kazanskaya, Krupnozernaya, Novozybkovskaya 4, Alfa, Derzhavinskaya 29, Chulpan, and Rossul, as well as wild populations of the perennial rye Secale montanum. This study was first to demonstrate that the resistance of the Kharkovskaya 55 and Rossul rye cultivars to the population of stem rust was controlled by a single dominant gene, which was designated Sr1.
