Genetic control of effective leaf rust resistance in collection accessions of barley Hordeum vulgare L.

Genetic control of effective leaf rust resistance in collection accessions of barley Hordeum... Leaf rust resistance was studied in barley accessions from the world collection of the Vavilov All-Russia Institute of Plant Industry. Most accessions described as highly resistant in the literature proved susceptible. High resistance at the juvenile stage was observed only for the cultivars Henry, Cebada Capa, Forrajera Klein, and Scarlet. Hybrid analysis and phytopathological tests showed that the cultivar Scarlet had one dominant resistance gene, Rph7. Adult resistance was demonstrated for accession NB-3002 from Nepal, which proved to have one dominant gene on evidence of hybrid analysis. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

Leaf rust resistance was studied in barley accessions from the world collection of the Vavilov All-Russia Institute of Plant Industry. Most accessions described as highly resistant in the literature proved susceptible. High resistance at the juvenile stage was observed only for the cultivars Henry, Cebada Capa, Forrajera Klein, and Scarlet. Hybrid analysis and phytopathological tests showed that the cultivar Scarlet had one dominant resistance gene, Rph7. Adult resistance was demonstrated for accession NB-3002 from Nepal, which proved to have one dominant gene on evidence of hybrid analysis.
